# 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."``); ` ` `  `        ``// Interate 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(); ` `    ``} ` `} `
