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
import java.util.Scanner;
public class GFG {
public static void
guessingNumberGame()
{
Scanner sc = new Scanner(System.in);
int number = 1 + ( int )( 100
* Math.random());
int K = 5 ;
int i, guess;
System.out.println(
"A number is chosen"
+ " between 1 to 100."
+ "Guess the number"
+ " within 5 trials." );
for (i = 0 ; i < K; i++) {
System.out.println(
"Guess the number:" );
guess = sc.nextInt();
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);
}
}
public static void
main(String arg[])
{
guessingNumberGame();
}
}

Output:
Below is the output of the above program:
