Question

In java

Modify your finished guessNumber.java program to include a random number generator to generate the guessed number (from 1 to 10). use the Random class to generate a random number between a range of integers. In your program include an if … then statement to check if the number you entered is bigger or smaller than the guessed number, and display a message. Also included is a counter to keep track on how many times the user has guessed, and display it at then end.

Below is the java code that needs to be modified:

/* Week3 in-class exercise
Name: numberGuess.java
Author: Your Name
Date:

*/

// need the Scanner class to get user input
import java.util.Scanner;

public class numberGuess {

/**
* @param args
*/
public static void main(String[] args) {
// TODO:
//
// a. declare a final int, and assign a value of 6 as the guessed number
           final int guessed_number = 6;

// b. create a Scanner to get user input
           Scanner input = new Scanner(System.in);
// c. use a do {} while loop to prompt the user to enter an integer between 1 and 10,
// assign the user input to an int, and compare to the guessing number
           int userInput = 0;
do{
System.out.println("Please enter an integer between 1 and 10.");
userInput = input.nextInt();
} while (userInput != guessed_number);

// d. if the number matches the guessed number,
// print out a message that the number entered is correct.
   System.out.println("\nNice! You entered the correct number.\n");

// Here is to print your name
System.out.println("Author: Your Name");
}

}

import java.util.Random;
import java.util.Scanner;

public class GuessNumberRandom {

   public static void main(String[] args) {
      
       int cnt=1;
       // a. declare a final int, and assign a value of 6 as the guessed number
       Random randomNumbers = new Random();
final int guessed_number = randomNumbers.nextInt(10);

   //b. create a Scanner to get user input
   Scanner input = new Scanner(System.in);
   //c. use a do {} while loop to prompt the user to enter an integer between 1 and 10,
   //assign the user input to an int, and compare to the guessing number
   int userInput = 0;
   do{
       System.out.println("Please enter an integer between 1 and 10.");
       userInput = input.nextInt();
      
       if(userInput==guessed_number)
       {
           System.out.println("\nNice! You entered the correct number.\n");
           break;
       }
       else if(userInput>guessed_number)
       {
           System.out.println("Higher then number");
       }
       else if(userInput<guessed_number)
       {
           System.out.println("lower then number");
       }
       cnt+=1;
      
   } while (userInput != guessed_number);
  
   System.out.println("total attempt of correct guess is: "+cnt);
  
  
   System.out.println("Author: Your Name");
   }
