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:Â Â
- 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:Â
Java
// Java program for the above approachimport java.util.Scanner;Â
public class GFG {Â
    // Function that implements the    // number guessing game    public static void    guessingNumberGame()    {        // Scanner Class        Scanner sc = new Scanner(System.in);Â
        // Generate the numbers        int number = 1 + (int)(100                               * Math.random());Â
        // Given K trials        int K = 5;Â
        int i, guess;Â
        System.out.println(            "A number is chosen"            + " between 1 to 100."            + "Guess the number"            + " within 5 trials.");Â
        // Iterate over K Trials        for (i = 0; i < K; i++) {Â
            System.out.println(                "Guess the number:");Â
            // Take input for guessing            guess = sc.nextInt();Â
            // 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);            }        }Â
        if (i == K) {            System.out.println(                "You have exhausted"                + " K trials.");Â
            System.out.println(                "The number was " + number);        }    }Â
    // Driver Code    public static void    main(String arg[])    {Â
        // Function Call        guessingNumberGame();    }} |
Output:Â
Below is the output of the above program:Â
