Java Arithmetic Operators

The Java programming language provides operators that perform addition, subtraction, multiplication, and division. There's a good chance you'll recognize them by their counterparts in basic mathematics. The only symbol that might look new to you is "%", which divides one operand by another and returns the remainder as its result.

OperatorDescription
+Additive operator (also used for String concatenation)
-Subtraction operator
*Multiplication operator
/Division operator
%Remainder operator

You can also combine the arithmetic operators with the simple assignment operator to create compound assignments. For example, x+=1; and x=x+1; both increment the value of x by 1.

The + operator can also be used for concatenating (joining) two strings together, as shown in the following ConcatDemo program:

public class ConcatString {
    public static void main(String[] args){
        String firststr  = "My Java ";
        String secondstr = "Training Institute";
        String resultstr = firststr+secondstr;
        System.out.println(resultstr);
    }
}

  

Simple Java Program Using Arithmetic operator:

class ArithmeticOp {

    public static void main (String[] args) {

        int a = 50;
        int b = 10;
        int add = a+b;
        // using '+' operator for addition
        System.out.println("The addition is = " + add);
        

        add = a-b;
        // Now using '-' operator for substraction
        System.out.println("The Substraction is:="+ add);
        

        add = a*b;
        // Now using '*' operator for multiplication
        System.out.println("The Multiplication is:="+ add);

        add = a/b;
       // Now using '/' operator for Dividation
        System.out.println("The Dividation is:="+ add);
        
        
        add = a%b;
        // Now using '%' operator for Remainder(percent)
         System.out.println("The Totel Percent is:="+ add);

       
    }
}
