# Arithmetic Operators

Posted By: Halima Khan     Category: Java     Views: 71804

Arithmetic operators are used to perform mathematic operations on multiple expressions. We can use these operators with numeric or char data type. If we compare different types of variables or values, then the narrower type converted to wider type.

Below are the arithmetic operators available in java.

### Arithmetic Operators in java

 Operator Meaning Example + Addition a + b - Subtraction a - b * Multiplication a * b / Division a / b % Modulo a % b +1 Unary Plus +4 -1 Unary Minus -4

### Precedence of Arithmetic Operators

 Highest to Lowest Operator 1 *, /, % 2 +, -

### Syntax of Arithmetic Operators

op1 arthOptr op2

op1 is a first operand to compare.
op2 is a second operand to compare.
arthOptr is a arithmetic operator.

### Example 1 : Program that displays use of all arithmetic operators i.e +, -, *, /, %

class ArthOptrDemo
{
public static void main(String[] args)
{
int a = 10, b = 15, c = 15;
System.out.println("Arithmetic Operators and returned values");
System.out.println(" a + b = " + (a + b));
System.out.println(" b - a  = " + (b - a));
System.out.println(" a * 2  = " + (a * 2));
System.out.println(" b / 5 = " + (b / 5));
System.out.println(" b % 2 = " + (b % 2));
System.out.println(" Unary plus = " + +2));
System.out.println(" Unary minus = " + -2);

}
}

Output

Arithmetic Operators and returned values
a + b = 25
b - a = 5
a * 2 = 20
b / 5 = 3
b % 2 = 1
Unary plus = 2
Unary minus = -2
