Java Arithmetic Operators

The Java programming language has includes five simple arithmetic operators like are + (addition), - (subtraction), * (multiplication), / (division), and % (modulo). The following table summarizes the binary arithmetic operators in the Java programming language.
The relation operators in Java are: ==, !=, <, >, <=, and >=. The meanings of these operators are:

Use Returns true if
op1 + op2 op1 added to op2
op1 - op2  op2 subtracted from op1
op1 * op2  op1 multiplied with op2
op1 / op2  op1 divided by op2
op1 % op2  Computes the remainder of dividing op1 by op2

The following java program, ArithmeticProg , defines two integers and two double-precision floating-point numbers and uses the five arithmetic operators to perform different arithmetic operations. This program also uses + to concatenate strings.

public class ArithmeticProg
    {
         public static void main(String[] args)
        {
            //a few numbers
            int i = 10;
            int j = 20;
            double x = 10.5;
            double y = 20.5; //adding numbers
            System.out.println("Adding");
            System.out.println(" i + j = " + (i + j));
            System.out.println(" x + y = " + (x + y)); //subtracting numbers
            System.out.println("Subtracting");
            System.out.println(" i - j = " + (i - j));
            System.out.println(" x - y = " + (x - y)); //multiplying numbers
            System.out.println("Multiplying");
            System.out.println(" i * j = " + (i * j));
            System.out.println(" x * y = " + (x * y)); //dividing numbers
            System.out.println("Dividing");
            System.out.println(" i / j = " + (i / j));
            System.out.println(" x / y = " + (x / y)); //computing the remainder resulting //from dividing numbers
            System.out.println("Modulus");
            System.out.println(" i % j = " + (i % j));
            System.out.println(" x % y = " + (x % y));
         }
     }
