The following example show you how to use Java arithmetic operators. The operators consist of the multiplicative operators (* for multiplication, / for division), % for remainder of division) and the additive operators (+ for addition,- for subtraction).
You’ll also see we are using a combination of a simple assignment operator with the arithmetic operators to create compound assignments.
package org.kodejava.basic;
public class ArithmeticOperatorsDemo {
public static void main(String[] args) {
int result = 5 + 4; // result = 9
System.out.println("result = " + result);
result = result - 2; // result = 7
System.out.println("result = " + result);
result = result * 4; // result = 28
System.out.println("result = " + result);
result = result / 7; // result = 4
System.out.println("result = " + result);
result = result % 3; // result = 1
System.out.println("result = " + result);
// Combining the arithmetic operators with a simple assignment
// operators give us a compound assignment. We can write the
// operation above in the following form. But as you can see
// the above snippets is easier to read.
result = 5 + 4; // result = 9
System.out.println("result = " + result);
result -= 2; // result = 7
System.out.println("result = " + result);
result *= 4; // result = 28
System.out.println("result = " + result);
result /= 7; // result = 4
System.out.println("result = " + result);
result %= 3; // result = 1
System.out.println("result = " + result);
}
