Arithmetic Operators

Arithmetic operators in Java are used to perform mathematical operations on numeric data types.

We can perform basic mathematical operations with numbers.

int a = 4;
int b = 5;

Addition (+)

Adds the two inputs.

System.out.println(a + b); // prints 9

Subtracts the right operand/value from the left value.

System.out.println(a - b); // prints -1

Multiplies the two inputs.

System.out.println(a * b); // prints 20

Use / (forward slash) for division. It divides the left operand by the right operand.

Integer division truncated any fractional part.

System.out.println(a / b); // prints 20
