Assignment Operators J8 Home   «   Assignment Operators

  • <<    Relational & Logical Operators
  • Bitwise Logical Operators     >>

Symbols used for mathematical and logical manipulation that are recognized by the compiler are commonly known as operators in Java. In the third of five lessons on operators we look at the assignment operators available in Java.

Assignment Operators Overview  Top

The single equal sign = is used for assignment in Java and we have been using this throughout the lessons so far. This operator is fairly self explanatory and takes the form variable = expression; . A point to note here is that the type of variable must be compatible with the type of expression .

Shorthand Assignment Operators

The shorthand assignment operators allow us to write compact code that is implemented more efficiently.

Automatic Type Conversion, Assignment Rules  Top

The following table shows which types can be assigned to which other types, of course we can assign to the same type so these boxes are greyed out.

When using the table use a row for the left assignment and a column for the right assignment. So in the highlighted permutations byte = int won't convert and int = byte will convert.

Casting Incompatible Types  Top

The above table isn't the end of the story though as Java allows us to cast incompatible types. A cast instructs the compiler to convert one type to another enforcing an explicit type conversion.

A cast takes the form     target = (target-type) expression .

There are a couple of things to consider when casting incompatible types:

  • With narrowing conversions such as an int to a short there may be a loss of precision if the range of the int exceeds the range of a short as the high order bits will be removed.
  • When casting a floating-point type to an integer type the fractional component is lost through truncation.
  • The target-type can be the same type as the target or a narrowing conversion type.
  • The boolean type is not only incompatible but also inconvertible with other types.

Lets look at some code to see how casting works and the affect it has on values:

Running the Casting class produces the following output:

run casting

The first thing to note is we got a clean compile because of the casts, all the type conversions would fail otherwise. You might be suprised by some of the results shown in the screenshot above, for instance some of the values have become negative. Because we are truncating everything to a byte we are losing not only any fractional components and bits outside the range of a byte , but in some cases the signed bit as well. Casting can be very useful but just be aware of the implications to values when you enforce explicit type conversion.

Java Programming tutorials

Java provides many types of operators to perform a variety of calculations and functions, such as logical , arithmetic , relational , and others. With so many operators to choose from, it helps to group them based on the type of functionality they provide. This programming tutorial will focus on Java’s numerous a ssignment operators.

Before we begin, however, you may want to bookmark our other tutorials on Java operators, which include:

  • Arithmetic Operators
  • Comparison Operators
  • Conditional Operators
  • Logical Operators
  • Bitwise and Shift Operators

Assignment Operators in Java

As the name conveys, assignment operators are used to assign values to a variable using the following syntax:

The left side operand of the assignment operator must be a variable, whereas the right side operand of the assignment operator may be a literal value or another variable. Moreover, the value or variable on the right side must be of the same data type of the operand on the left side. Otherwise, the compiler will raise an error. Assignment operators have a right to left associativity in that the value given on the right-hand side of the operator is assigned to the variable on the left. Therefore, the right-hand side variable must be declared before assignment.

You can learn more about variables in our programming tutorial: Working with Java Variables .

Types of Assignment Operators in Java

Java assignment operators are classified into two types: simple and compound .

The Simple assignment operator is the equals ( = ) sign, which is the most straightforward of the bunch. It simply assigns the value or variable on the right to the variable on the left.

Compound operators are comprised of both an arithmetic, bitwise, or shift operator in addition to the equals ( = ) sign.

Equals Operator (=) Java Example

First, let’s learn to use the one-and-only simple assignment operator – the Equals ( = ) operator – with the help of a Java program. It includes two assignments: a literal value to num1 and the num1 variable to num2 , after which both are printed to the console to show that the values have been assigned to the numbers:

The += Operator Java Example

A compound of the + and = operators, the += adds the current value of the variable on the left to the value on the right before assigning the result to the operand on the left. Here is some sample code to demonstrate how to use the += operator in Java:

The -= Operator Java Example

Made up of the – and = operators, the -= first subtracts the variable’s value on the right from the current value of the variable on the left before assigning the result to the operand on the left. We can see it at work below in the following code example showing how to decrement in Java using the -= operator:

The *= Operator Java Example

This Java operator is comprised of the * and = operators. It operates by multiplying the current value of the variable on the left to the value on the right and then assigning the result to the operand on the left. Here’s a program that shows the *= operator in action:

The /= Operator Java Example

A combination of the / and = operators, the /= Operator divides the current value of the variable on the left by the value on the right and then assigns the quotient to the operand on the left. Here is some example code showing how to use the  /= operator in Java:

%= Operator Java Example

The %= operator includes both the % and = operators. As seen in the program below, it divides the current value of the variable on the left by the value on the right and then assigns the remainder to the operand on the left:

Compound Bitwise and Shift Operators in Java

The Bitwise and Shift Operators that we just recently covered can also be utilized in compound form as seen in the list below:

  • &= – Compound bitwise Assignment operator.
  • ^= – Compound bitwise ^ assignment operator.
  • >>= – Compound right shift assignment operator.
  • >>>= – Compound right shift filled 0 assignment operator.
  • <<= – Compound left shift assignment operator.

The following program demonstrates the working of all the Compound Bitwise and Shift Operators :

Final Thoughts on Java Assignment Operators

This programming tutorial presented an overview of Java’s simple and compound assignment Operators. An essential building block to any programming language, developers would be unable to store any data in their programs without them. Though not quite as indispensable as the equals operator, compound operators are great time savers, allowing you to perform arithmetic and bitwise operations and assignment in a single line of code.

Java - Compound Boolean Logical Assignment Operators

What are compound boolean logical assignment operators.

There are three compound Boolean logical assignment operators.

The operand1 must be a boolean variable and op may be &, |, or ^.

Java does not have any operators like &&= and ||=.

Compound Boolean Logical Assignment Operators are used in the form

The above form is equivalent to writing

The following table lists the compound logical assignment operators and their equivalents.

For &= operator, if both operands evaluate to true, &= returns true. Otherwise, it returns false.

For != operator, if either operand evaluates to true, != returns true. Otherwise, it returns false.

For ^= operator, if both operands evaluate to different values, that is, one of the operands is true but not both, ^= returns true. Otherwise, it returns false.

Boolean Operators

Java also supports most of the Boolean operators discussed earlier in the chapter. Let’s look at a few examples.

In Java, the not operator is the exclamation point ! , placed before a Boolean value. It will invert the value of the variable, changing true to false and false to true .

Here is a quick example:

This program will output false , which is the inverted value of b .

And &&

To perform the and operation, Java uses two ampersands && placed between Boolean values. Let’s look at an example:

This program will output true on the first line, since we know that both a and b are true . On the second line, it will output false , since c is false , even though b is true .

Similarly, Java uses two vertical pipes || to represent the or operator. On most keyboards, we can find that key above the Enter key. Here’s an example of how it can be used in code:

Once again, this program will output true on the first line, since a is true , even though b is false . On the second line, it will output false , since both b and c are false .

According to the Java documentation, Java also supports using a single & for and , and a single | for or when dealing with Boolean values. Why shouldn’t we just use these operators instead?

It turns out that there is a fundamental difference in how the Java compiler handles these operators. The double-character operators && and || are called logical operators and short-circuit operators . In some scenarios, the system only needs to look at the first value in the statement to determine the result. For example, the statement x || (y || z) will always be true if x is true , without needing to consider the values in y or z . The same works for x && (y && z) when x is false , which will result in the entire statement being false . For larger Boolean expressions, the use of these short-circuit operators can make our programs run much faster and more efficiently.

The single-character operators & and | bit-wise comparison operators and are not short-circuited. So, the system will evaluate each part of the statement before determining the outcome. For boolean values, the bit-wise operators will evaluate to the same answer as the logical operators.

However you should not use them for this purpose. First, because they will slow your programs executions. Second, because it will obscure your intent to future readers of your program. At some distance point in the future, a programmer will see you used a bit-wise operator, assume there must be a reason you did not using the logical one, and lose valuable time trying to figure out why you did not use the logical operator.

You can read more about Bitwise Operations on Wikipedia. We will not use them in this course.

Exclusive Or

Java does not support a logical exclusive or , but we can build a similar statement using other operators.

In this example, the first line will be true , since a is true but b is false . However, the second line will output false , since both a and c are true .

Comparison Operators

We can also use the comparison operators == , != , < , <= , > , and >= to compare variables containing numbers, which will result in a Boolean value. Here’s an example showing those operators in action:

As we can see, each of the comparison operators works just as we’d expect, and outputs a Boolean value of either true or false , depending on the result of the comparison.

Like most high level languages, Java does not allow the chaining of comparison operators. 10 <= x <=20 , which is a pretty standard math notation for x is between 10 and 20, will not work. First the compiler will evaluate 10 <=x as a boolean, then it will throw a fit about trying to compare a boolean and and int for the <= 20 part.

You will need to write this as 10 <= x && x <= 20 .

Order of Operations

Now that we’ve introduced some additional operators, we should also see where they fit in with the other operators in Java. Here is an updated list giving the appropriate operator precedence for Java, with new entries in bold :

  • Parentheses
  • Postfix: Increment ++ & Decrement -- after variable*
  • Prefix: Inverse - , Not ! , Increment ++ & Decrement -- before variable*
  • Multiplicative : Multiplication * , Division / , and Modulo %
  • Additive : Addition + , Subtraction -
  • Relational : < , > , <= , >=
  • Equality : == , !=
  • Logical And : &&
  • Logical Or : ||
  • Assignment : = , += , -= , *= , /= , %=

Java methods, java classes, java file handling, java how to's, java reference, java examples, java booleans.

Very often, in programming, you will need a data type that can only have one of two values, like:

  • TRUE / FALSE

For this, Java has a boolean data type, which can store true or false values.

Boolean Values

A boolean type is declared with the boolean keyword and can only take the values true or false :

Try it Yourself »

However, it is more common to return boolean values from boolean expressions, for conditional testing (see below).

Boolean Expression

A Boolean expression returns a boolean value: true or false .

This is useful to build logic, and find answers.

For example, you can use a comparison operator , such as the greater than ( > ) operator, to find out if an expression (or a variable) is true or false:

Or even easier:

In the examples below, we use the equal to ( == ) operator to evaluate an expression:

Real Life Example

Let's think of a "real life example" where we need to find out if a person is old enough to vote.

In the example below, we use the >= comparison operator to find out if the age ( 25 ) is greater than OR equal to the voting age limit, which is set to 18 :

Cool, right? An even better approach (since we are on a roll now), would be to wrap the code above in an if...else statement, so we can perform different actions depending on the result:

Output "Old enough to vote!" if myAge is greater than or equal to 18 . Otherwise output "Not old enough to vote.":

Booleans are the basis for all Java comparisons and conditions.

You will learn more about conditions ( if...else ) in the next chapter.
