Help needed with constructing a while loop please!

My task is to: Prompt the user for and read in the number of guesses the user wants at the random number.
2. Generate (but not immediately display) the random number between 1 and 100.
3. As long as the user has not yet guessed the random number and the number of guesses
allowed has not been exceded:
• Prompt the user to enter their next guess at the generated random number.
• If the guess is smaller than the actual random number, print out a message indicating
that the user’s guess is too small.
• If the guess is larger than the actual random number, print out a message indicating
that the user’s guess is too large.
4. If the user succeeded in guessing the random number, then print out a congratulatory
message and tell them how many guesses they took.
5. If the user did not succeed in guessing the random number, the number should be displayed.

Code :

---

import java.util.*;
 
public class SimpleGame {
 
public static void main(String args[])
    {
    int numGuess;
    int userGuess;
 
    // Prompt User for Number of guesses as well as What guess the user intends to input
    Scanner kbd = new Scanner(System.in);
    System.out.print("How many guesses do you want?");
    numGuess = kbd.nextInt();
 
    System.out.println("What is your guess?");
    userGuess = kbd.nextInt();
 
 
    while (numGuess == 1)
 
    {
           if (userGuess == 63)
               System.out.print("Congratulations, you guessed the number right!");
           else if (userGuess >= 63)
               System.out.println("Sorry, your guess is too high");
           else if (userGuess <= 63)
               System.out.println("Sorry, your guess is too low");
               System.out.println("The number was 63");
           break;
 
    }        
 
while (numGuess == 2)
 
    {
           if (userGuess == 36)
               System.out.print("Congratulations, you guessed the number right!");
           else if (userGuess >= 36)
               System.out.println("Sorry, your guess is too high");
           else if (userGuess <= 36)
               System.out.println("Sorry, your guess is too low");
               System.out.println("The number was 36");
           userGuess += 2;
           numGuess += 2;
           break;
 
    }

So when i run this, it prompts me once yeah but i am a bit confused as to how i may get it to prompt me 2 or 3 or 4...etc times in a row, so if anyone could assist me with this, that would be very helpful.

thanks

A way to accomplish that is with a do...while loop. You can first ask the user how many guesses he want and then execute the do block as many times as the guesses.

thank you, i have done that

Code :

---

public class SimpleGame {
 
public static void main(String args[])
	{
	int numGuess;
	int userGuess = 0;
	Scanner kbd = new Scanner(System.in);
 
 
 
 
 
 
	do 
	{
		//Prompt User for Number of guesses as well as What guess the user intends to input
		System.out.print("How many guesses do you want?");
		numGuess = kbd.nextInt();
 
		System.out.println("What is your guess?");
 
		if (numGuess == 1)
		{
		userGuess = kbd.nextInt();
		}
 
		if (numGuess == 2)
		{	
		userGuess = kbd.nextInt();
		userGuess = kbd.nextInt();
 
		}
		if (numGuess == 3) 
		{
		userGuess = kbd.nextInt();
		userGuess = kbd.nextInt();
		userGuess = kbd.nextInt();
		}
		if (numGuess == 4)
		{	
		userGuess = kbd.nextInt();
		userGuess = kbd.nextInt();
		userGuess = kbd.nextInt();
		userGuess = kbd.nextInt();
		}
 
		if (numGuess ==5)
		{
			userGuess = kbd.nextInt();
			userGuess = kbd.nextInt();
			userGuess = kbd.nextInt();
			userGuess = kbd.nextInt();
			userGuess = kbd.nextInt();
 
		}
 
 
		if (numGuess ==6)
		{
			userGuess = kbd.nextInt();
			userGuess = kbd.nextInt();
			userGuess = kbd.nextInt();
			userGuess = kbd.nextInt();
			userGuess = kbd.nextInt();
			userGuess = kbd.nextInt();
 
 
		}
 
		if (numGuess ==7)
		{
			userGuess = kbd.nextInt();
			userGuess = kbd.nextInt();
			userGuess = kbd.nextInt();
			userGuess = kbd.nextInt();
			userGuess = kbd.nextInt();
			userGuess = kbd.nextInt();
			userGuess = kbd.nextInt();
		}
 
		if (numGuess ==8)
		{
			userGuess = kbd.nextInt();
			userGuess = kbd.nextInt();
			userGuess = kbd.nextInt();
			userGuess = kbd.nextInt();
			userGuess = kbd.nextInt();
			userGuess = kbd.nextInt();
			userGuess = kbd.nextInt();
			userGuess = kbd.nextInt();
 
		}
 
 
}
 
 
 
	while (numGuess == userGuess);
 
 
	       if (userGuess == 63)
	    	   System.out.print("Congratulations, you guessed the number right!");
	       else if (userGuess >= 63)
	    	   System.out.println("Sorry, your guess is too high");
	       else if (userGuess <= 63)
	    	   System.out.println("Sorry, your guess is too low");
	           System.out.println("The number was 63");
 
 
 
 
	}
}

now, i need to find a way to implement a infinite amount of guesses, if you could assist me with this, that would be great.

thanks

I have tried to simplify the code as my previous code was a bit much
this is how it looks:

Code :

---

 
 
 
import java.util.*;
public class SimpleGme2 {
 
 
	public static void main(String args[])
	{
	int counter = 0;
	int numGuess;
	int userGuess = 0;
	Scanner kbd = new Scanner(System.in);
	Random n = new Random ();
	int number = 0;
 
 
	//Prompt User for Number of guesses as well as What guess the user intends to input
	    System.out.print("How many guesses do you want?");
 
 
 
	while (counter < 10)
	{
		number = n.nextInt();
		numGuess = kbd.nextInt();
 
	if (number == 63 )
		System.out.print("Congratulations, you guessed the number right!");
	    break;	
		}
 
	if (number >= 63)
		System.out.println("Sorry, your guess is too high");
 
	else if (number <= 63)
		System.out.println("Sorry, your guess is too low");
 
 
 
 
 
 
 
	}
}

thanks

Okay there is a problem with your pseudo-code. This is what your program is doing:

Code :

---

Do infinite number of times   (note that the counter is never incremented so it will never be greater than 10)
   Generate a random number  (note that this is never used)
   Ask the user for a number
   If number == 63  print "Congratulations"
   If number < 63 print "Higher"
   If number > 63 print "Lower"
End do

---

Here is the proper pseudo-code for a higher/lower game

Code :

---

Do
   Ask the user for the maximumNumberOfGuesses
   Generate a random number (number)
   Set guessCount == 0
   Do
      Ask the user for an input (userInput)
      Increment the guess count (count)
      If count > maximumNumberOfGuesses
          print "You have run out of guesses. You Loose."
          print "The correct answer was: " + number
          exit Do
      If number < userInput print "Higher"
      If number > userInput print "Lower"
      If number == userInput 
          print "Congratulations. You Win."
          Ask if the user wants to play again
          if true
             go to start of the program
          else
             exit program
       End do
End do

I cannot just give you the code for this as it would rob you of the learning experience. In fact providing you with the pseudo-code like this is probably the same thing because this is an exercise in structuring a program.

Do me a favor and take a look at how I analyzed the question and wrote it out as a step of instructions that a human could follow step by step. This is called pseudo-code and it is essential for structuring your programs correctly. Your code is pretty good for a new programmer but I wanted to help you out here because the code reminded me of my own when I first started; syntactically correct but schematically wrong. So PLEASE do not just look at this pseudo-code and start writing code. Go over the question again and write your own pseudo-code. Compare it to mine if you need. Then start writing code. My golden rule is; every 10 minutes of planning will save you 1hr of programming.

Christopher Lowe, thank you for the help, i will put your advise to good use.

Thanks once again.
