Answer 1

CODE:

import java.util.*;
public class Main
{
   public static void main(String[] args) {

Scanner sc = new Scanner(System.in);

System.out.print("Input the first number: ");
int num1 = sc.nextInt();

System.out.print("Input the second number: ");
int num2 = sc.nextInt();

System.out.print("Input the third number: ");
int num3 = sc.nextInt();
// Check if num1 is greater than other 2 numbers
if (num1 > num2)
if (num1 > num3)
System.out.println("The greatest number: " + num1);
// Check if num2 is greater than other 2 numbers
if (num2 > num1)
if (num2 > num3)
System.out.println("The greatest number: " + num2);
   // Check if num3 is greater than other 2 numbers
if (num3 > num1)
if (num3 > num2)
System.out.println("The greatest number: " + num3);
}
}

OUTPUT:

Input the first number: 35                                                                                                    

Input the second number: 28                                                                                                   

Input the third number: 87                                                                                                    

The greatest number: 87

SUMMARY:

The above code is written in java as instructed. First we scan the value from user by asking to input 3 numbers. Then using if statements we find the greatest of 3 numbers and print the output accordingly.
