Program or Solution

``` import java.util.*; class Checker { public static void main(String args[]) { int num1,num2,num3; Scanner sc=new Scanner(System.in); System.out.println("Enter three numbers:"); num1=sc.nextInt(); num2=sc.nextInt(); num3=sc.nextInt(); if((num1 > num2) && (num1 > num3)) { System.out.println("The Greatest Is "+num1); } else if(num2 > num3) { System.out.println("The Greatest Is "+num2); } else { System.out.println("The Greatest Is "+num3); } } } ```

Program Explanation

1. Get three inputs num1,num2 and num3 from user using scanner class

2. check whether num1 is greater than num2 and num1 is greater than num3 using if statement.

if num1 is greater

2a. print num1 using system.out.println,

else

2b. check whether num2 is greater than num1 using elseif statement.

If num2 is greater

2b1. print num2 using printf statement,

else

2b2. print num3 using system.out.println.
