Very simple game about Guessing The Number
/hello, I am trying to learn how to use "break" commend in java as well as continuing loop with "y or n" choice. I am writing this game Guessing Number and I have some trouble with "y" choice. I will try to explain, to write a game of guessing number was easy so I started to add some conditions like the possibility on the and to play again or not, later I was thinking that would be more interesting if I add possibility to quit any time player wish, but that does not working correctly. Please help, thats my code
package guessinggame;
import java.util.Random;
import java.util.Scanner;
/**
*
public class Main {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
System.out.println(" Welcome ");
Random rand = new Random();
Scanner input = new Scanner(System.in);
boolean play_again = true;
while (play_again)
{
int number_guess = rand.nextInt(100)+1;
int number_of_tries = 0;
int guess;
String another = "y";
boolean win = false;
while (win == false)
{
System.out.println(" Try too guess a number between 1 and 100 ");
guess = input.nextInt();
number_of_tries++;
if (guess == number_guess)
{
win = true;
}
else if (guess < number_guess)
{
System.out.println(" Guess is too low " + "\n Guess another number to continue or n to quit ");
if (input.hasNext("n"))
{
play_again = false;
break;
}
}
else if (guess > number_guess)
{
System.out.println(" Guess is too high " + "\n Guess another number to continue or n to quit ");
if (input.hasNext("n"))
{
play_again = false;
break;
}
}
}
System.out.println(" You Win!!! ");
System.out.println(" The number was " + number_guess);
System.out.println(" It took you " + number_of_tries + " tries " +
"\nWould you like to play again? (y/n): ");
if (another.equalsIgnoreCase("y") == true)
play_again = true;
else
{
play_again = false;
}
}
}
}

This will work.
package aa;
import java.util.Random;
import java.util.Scanner;
public class abc {
public static void main(String[] args) {
System.out.println(" Welcome ");
Random rand = new Random();
Scanner input = new Scanner(System.in);
boolean play_again = true;
while (play_again)
{
int number_guess = rand.nextInt(100)+1;
int number_of_tries = 0;
int guess;
String another = "y";
boolean win = false;
while (win == false)
{
System.out.println(" Try too guess a number between 1 and 100 ");
guess = input.nextInt();
number_of_tries++;
if (guess == number_guess)
{
win = true;
break;
}
else if (guess < number_guess)
{
System.out.println(" Guess is too low " + "\n Guess another number to continue or n to quit ");
if (input.hasNext("n"))
{
play_again = false;
break;
}
}
else if (guess > number_guess)
{
System.out.println(" Guess is too high " + "\n Guess another number to continue or n to quit ");
if (input.hasNext("n"))
{
play_again = false;
break;
}
}
}
input.next();
if (win == true){
System.out.println(" You Win!!! ");
}
else{
System.out.println(" Good Luck Next Time!!! ");
System.out.println(" The number was " + number_guess);
}
System.out.println(" It took you " + number_of_tries + " tries " +
"\nWould you like to play again? (y/n): ");
another = input.next();
if (another.equalsIgnoreCase("y") == true)
play_again = true;
else
{
play_again = false;
}
}
System.out.println("Thank you!!!");
}
}

Here is an alternative that achieves that same outcome
public class Main {
/**
* @param args the command line arguments
*/
public static void main(String[] args)
{
System.out.println(" Welcome ");
Random rand = new Random();
Scanner input = new Scanner(System.in);
int guess = 0;
int number_of_tries = 0;
System.out.println(" Try too guess a number between 1 and 100 -1 to close");
guess = input.nextInt(); //get first input
while (guess != -1)
{
int number_guess = rand.nextInt(5) + 1;
++number_of_tries;
//check if user wins and exits loop
if (isWin (number_guess,guess))
{
System.out.println(" You Win!!! ");
System.out.println(" The number was " + number_guess);
System.out.println(" It took you " + number_of_tries + " tries " +
"\nWould you like to play again? [1 yes/ -1 no]: ");
guess = input.nextInt();
if (guess == -1)
break;
else
System.out.println(" Try too guess a number between 1 and 100 -1 to close");
}
else if (number_guess < guess )
{
System.out.println(" Guess is too High " + "\n Guess another number to continue or -1 to quit ");
guess = input.nextInt();
continue;
}
else if (number_guess > guess)
{
System.out.println(" Guess is too low " + "\n Guess another number to continue or -1 to quit ");
guess = input.nextInt();
continue;
}
}
System.out.println ("bye bye");
}
public static boolean isWin (int number,int guess)
{
return (number == guess) ? true :false;
}
}

You forgot to wait for user input after this statement:
System.out.println(" It took you " + number_of_tries + " tries " +
"\nWould you like to play again? (y/n): ");
E.g. you could try next approach:
System.out.println(" It took you " + number_of_tries + " tries " +
"\nWould you like to play again? (y/n): ");
if (input.hasNext()) {
if (another.equalsIgnoreCase("y")) {
play_again = true;
input.next();
} else {
play_again = false;
}
}

It looks like your braces are messed up for your play again if statement
