Objetive

Write a java program that prompts the user to enter three numbers and displays the greatest one.

Example Code

import java.util.*;
public class Main
{
    public static void main(String[] args)
    {
        int number1, number2, number3;

        System.out.print("Enter the number 1:");
        number1 = Integer.parseInt(new Scanner(System.in).nextLine());

        System.out.print("Enter the number 2:");
        number2 = Integer.parseInt(new Scanner(System.in).nextLine());

        System.out.print("Enter the number 3:");
        number3 = Integer.parseInt(new Scanner(System.in).nextLine());

        if (number1 > number2 && number1 > number3)
        {
	        System.out.println("The number 1 is greatest");
        }
        else if (number2 > number1 && number2 > number3)
        {
	        System.out.println("The number 2 is greatest");
        }
        else if (number3 > number1 && number3 > number2)
        {
	        System.out.println("The number 3 is greatest");
        }
        else
        {
	        System.out.println("Numbers equals");
        }
    }
}
