Question

Develop an Algorithm and java program using Design Recipe for the following problems.

Draw a flowchart to compute the largest and smallest of 4 numbers

: Write a Java Program for the above flowchart, use methods(functions), and nested if-else statements. Take input from the user using the Scanner object. Use separate methods to compute the Largest and Smallest of the numbers. Method 1 Name: findLargest(param 1, param 2, param 3, param 4) Method 2 Name: findSmallest(param 1, param 2, param 3, param 4)

Answer 1

JAVA PROGRAM

import java.util.*;
import java.util.Scanner;

public class Main
{
   public static void main(String[] args)
   {
   Scanner sc = new Scanner(System.in);
   int num1,num2,num3,num4;
  
   System.out.println("Enter Numbers: ");
   //reads input from user
   num1 = sc.nextInt();
   num2 = sc.nextInt();
   num3 = sc.nextInt();
   num4 = sc.nextInt();
  
   // checks the condition for largest number
   if(num1 > num2 && num1 > num3 && num1 > num4)
   {
   System.out.println("Largest Number: "+num1);
     
   }
   else if(num2 > num1 && num2 > num3 && num2 > num4){
   System.out.println("Largets Number: "+num2);
   }
else if(num3 > num1 && num3 > num2 && num3 > num4)
{
System.out.println("Largest Number: "+num3);
}
else{
System.out.println("Largest Number: "+num4);
}
  
//checks the condition for Smallest Numbers
if(num1 < num2 && num1 < num3 && num1 < num4)
   {
   System.out.println("Smallest Number: "+num1);
   }
   else if(num2 < num1 && num2 < num3 && num2 < num4)
   {
   System.out.println("Smallest Number: "+num2);
   }
else if(num3 < num1 && num3 < num2 && num3 < num4)
{
System.out.println("Smallest Number: "+num3);
}
else
{
System.out.println("Smallest Number: "+num4);
}
  
  
   }
}
