Answer to Question #323950 in Java | JSP | JSF for Dreaper

Question

The program shall:

• generate a random number from 1 to 50 for a player to guess;

• display a message that indicates whether the player's guess is correct, too low, or too high; • prompt the user to keep on guessing until the correct value is entered

4. Create a try-catch structure that will handle two (2) exceptions. These are when the user inputs the following:

• a number that is out of range (1 - 50) a letter or any non-numeric character

5. Prompt the user so that he can guess again if an exception is thrown.

6. Display the number of total guesses.

Note: An invalid input (when an exception is thrown) is not considered a valid guess or attempt.

import java.nio.charset.MalformedInputException;
import java.util.InputMismatchException;
import java.util.Random;
import java.util.Scanner;

public class Main {
    public static void main(String[] args){
        Scanner in = new Scanner(System.in);
        Random rand = new Random();

        int che = rand.nextInt(51);
        int v = 0;
        do {

            System.out.print("Enter number: ");
            v = in.nextInt();

            try {
                if(0 > v & v > 50)
                    throw new IllegalArgumentException();
            } catch (IllegalArgumentException e){
                System.out.println("Input error!");
                continue;
            } catch (InputMismatchException e){
                System.out.println("Input error!");
                continue;
            }

            if(v > che)
                System.out.println("your number is higher");
            if(v < che)
                System.out.println("your number is less");

        }while(v!=che);
        System.out.println("Win");
    }
