Modulus and OpEquals Example - Class Work

This for Modulus example

// Demonstrate the % operator.

class Modulus {
  public static void main( String args []) {
 int x = 42;
 double y = 42.3;
        System.out.println("x mod 10 =" + x % 10);
  System.out.println( "y mod 10 =" + y % 10);
      } 
 }
 

This is for OpEquals Example

class OpEquals { // Demonstate several assignment operators.
  public static void main( String args []) {
 int a = 1, b = 2, c = 3;
 
 a+=5; b*=4; c+= a*b; c%=6;
        System.out.println("a =" + a); // a=1+5 = 6
  System.out.println("b =" + b); // b=2*4=8
  System.out.println("c =" + c); // c = 3+ (6*8)=51=> c%6 = 51%6=3
      } 
 }
 

This is class Room example

class  room
{
 public static void main(String[] args) 
 {
  int length=15;
  int width=25;
