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 approachimport 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:
