Types of Assignment Operators in Java

Java is a popular programming language that software developers use to construct a wide range of applications. It is a simple, robust, and platform-independent object-oriented language. There are various types of assignment operators in Java, each with its own function.

In this section, we will look at Java's many types of assignment operators, how they function, and how they are utilized.

Simple Assignment Operator (=)

To assign a value to a variable, use the basic assignment operator (=). It is the most fundamental assignment operator in Java. It assigns the value on the right side of the operator to the variable on the left side.

Example:

In the above example, the variable x is assigned the value 10.

Addition Assignment Operator (+=)

To add a value to a variable and subsequently assign the new value to the same variable, use the addition assignment operator (+=). It takes the value on the right side of the operator, adds it to the variable's existing value on the left side, and then assigns the new value to the variable.

Example

Subtraction Operator (-)

To subtract one numeric number from another, use the subtraction operator. All numeric data types, including integers and floating-point values, can be utilised with it. Here's an illustration:

Explanation

In this example, we create two integer variables, a and b, subtract b from a, and then assign the result to the variable c.

Multiplication Operator (*)

To combine two numerical numbers, use the multiplication operator. All numeric data types, including integers and floating-point values, can be utilised with it. Here's an illustration:

Explanation

In this example, we declare two integer variables, a and b, multiply their values using the multiplication operator, and then assign the outcome to the third variable, c.

Division Operator (/)

To divide one numerical number by another, use the division operator. All numeric data types, including integers and floating-point values, can be utilised with it. Here's an illustration:

Explanation

In this example, we declare two integer variables, a and b, divide them by one another using the division operator, and then assign the outcome to the variable c.

It's vital to remember that when two numbers are divided, the outcome will also be an integer, and any residual will be thrown away. For instance:

Modulus Assignment Operator (%=)

The modulus assignment operator (%=) computes the remainder of a variable divided by a value and then assigns the resulting value to the same variable. It takes the value on the right side of the operator, divides it by the current value of the variable on the left side, and then assigns the new value to the variable on the left side.

Output:

y = 10
x += 5: 15
x -= 3: 12
x *= 2: 24
x /= 4: 6
x %= 3: 0
x <<= 2: 0
x >>= 1: 0
x &= 5: 0
x |= 2: 2
x ^= 1: 3
