Today we created a number guessing game using Java. Good Luck going up against it!
import javax.swing.*;
public class Main {
public static void main(String[] args) {
// write your code here
System.out.println("Hello World");
int computerNumber = (int) (Math.random()*100 + 1); //generate random num
int userAnswer = 0; //initialize
// log correct answer to console for verification
System.out.println("The correct guess would be " + computerNumber);
int count = 1; //initialize
// Display input dialog until the user guesses the correct number
while (userAnswer != computerNumber)
{
String response = JOptionPane.showInputDialog(null,
"Enter a guess between 1 and 100", "Guessing Game", 3); // display initial input dialog to user
userAnswer = Integer.parseInt(response); //convert string to int for use in check method below
//pass userAnswer and the Compter gen number along with guess count to method
JOptionPane.showMessageDialog(null, ""+ determineGuess(userAnswer, computerNumber, count));
count++; //increment number of tries for each attempt
}
}
//Determine guess function to check how close number is to generated number and display try count
public static String determineGuess(int userAnswer, int computerNumber, int count){
if (userAnswer <=0 || userAnswer >100) {
return "Your guess is invalid";
}
else if (userAnswer == computerNumber ){
return "Correct!\nTotal Guesses: " + count;
}
else if (userAnswer > computerNumber) {
return "Your guess is too high, try again.\nTry Number: " + count;
}
else if (userAnswer < computerNumber) {
return "Your guess is too low, try again.\nTry Number: " + count;
}
else {
return "Your guess is incorrect\nTry Number: " + count;
}
}
}
