# Number guessing game in Java

The task is to write a Java program in which a user will get K trials to guess a randomly generated number. Below are the rules of the game:

• If the guessed number is bigger than the actual number, the program will respond with the message that the guessed number is higher than the actual number.
• If the guessed number is smaller than the actual number, the program will respond with the message that the guessed number is lower than the actual number.
• If the guessed number is equal to the actual number or if the K trials are exhausted, the program will end with a suitable message.

Approach: Below are the steps:

• The approach is to generate a random number using Math.random() method in Java.
• Now using a loop, take K input from the user and for each input print whether the number is smaller or larger than the actual number.
• If within K trials the user guessed the number correctly, print that the user won.
• Else print that he was not able to guess and then print the actual number.

Below is the implementation of the above approach:

## Java

 `// Java program for the above approach` `import` `java.util.Scanner;`   `public` `class` `GFG {`   `    ``// Function that implements the` `    ``// number guessing game` `    ``public` `static` `void` `    ``guessingNumberGame()` `    ``{` `        ``// Scanner Class` `        ``Scanner sc = ``new` `Scanner(System.in);`   `        ``// Generate the numbers` `        ``int` `number = ``1` `+ (``int``)(``100` `                               ``* Math.random());`   `        ``// Given K trials` `        ``int` `K = ``5``;`   `        ``int` `i, guess;`   `        ``System.out.println(` `            ``"A number is chosen"` `            ``+ ``" between 1 to 100."` `            ``+ ``"Guess the number"` `            ``+ ``" within 5 trials."``);`   `        ``// Iterate over K Trials` `        ``for` `(i = ``0``; i < K; i++) {`   `            ``System.out.println(` `                ``"Guess the number:"``);`   `            ``// Take input for guessing` `            ``guess = sc.nextInt();`   `            ``// If the number is guessed` `            ``if` `(number == guess) {` `                ``System.out.println(` `                    ``"Congratulations!"` `                    ``+ ``" You guessed the number."``);` `                ``break``;` `            ``}` `            ``else` `if` `(number > guess` `                     ``&& i != K - ``1``) {` `                ``System.out.println(` `                    ``"The number is "` `                    ``+ ``"greater than "` `+ guess);` `            ``}` `            ``else` `if` `(number < guess` `                     ``&& i != K - ``1``) {` `                ``System.out.println(` `                    ``"The number is"` `                    ``+ ``" less than "` `+ guess);` `            ``}` `        ``}`   `        ``if` `(i == K) {` `            ``System.out.println(` `                ``"You have exhausted"` `                ``+ ``" K trials."``);`   `            ``System.out.println(` `                ``"The number was "` `+ number);` `        ``}` `    ``}`   `    ``// Driver Code` `    ``public` `static` `void` `    ``main(String arg[])` `    ``{`   `        ``// Function Call` `        ``guessingNumberGame();` `    ``}` `}`

Output:

Below is the output of the above program:
