Question

Hey Mate! Solve the program in JAVA.
Write a program to display the greatest of three unequal numbers using Input stream reader.

Answer 1

Greatest of Three Numbers - Java

We are supposed to take user input with Input Stream Reader. We import the java.io package to implement it.

After creating a BufferedReader object, we take the user input using its String readLine() function.

Then, we use a few if conditional blocks to get the greatest of the three numbers. The program works even if any two or all numbers are equal.

$\rule{300}{1}$

import java.io.*;

public class GreatestNumber

{

   public static void main(String[] args) throws IOException

   {

       BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

       System.out.print("Enter the first number: ");

       int num1 = Integer.parseInt(br.readLine());

       System.out.print("Enter the second number: ");

       int num2 = Integer.parseInt(br.readLine());

       System.out.print("Enter the third number: ");

       int num3 = Integer.parseInt(br.readLine());  

       int greatestNumber = num1;  //Initialise with num1

       if(num1 < num2 || num1 < num3)  //If num1 is smaller than any of the other two numbers, go in

       {

           if(num1 <= num3 && num2 <= num3)    //Compare for num3 as greatest

           {

               greatestNumber = num3;

           }

           if(num1 <= num2 && num3 <= num2)    //Compare for num2 as greatest

           {

               greatestNumber = num2;

           }

       }

       System.out.println("The greatest number is: "+greatestNumber);  //Print Greatest Number

   }

}
