Program to find if the first number is greater than or less than or equal to the second number
public class Maximum { public static void main(String[] args) {
int x = 10; int y = 20; // complete this }}
// Program Multiples calculates the square and cube of a value public class Multiples{ public static void main(String[] args) { int VALUE = 5; System.out.println("The number is " + VALUE); int VALUE1 = VALUE*VALUE; System.out.println(“squared is " + VALUE1); int VALUE2 = VALUE*VALUE*VALUE; System.out.println(" cubed is " + VALUE2); } }
