我試圖解決這個任務爲我們的主題。我已經嘗試過了,但沒有使用JOptionPane
,但它工作正常,但是當我編輯它時有一個對話框,它沒有奏效。第一個對話框應該包含一個標題和要輸入的選項,最後一個應該讓用戶退出程序。用戶輸入他/她的選擇後,應出現一個對話框,指示用戶的選擇和計算機的選擇。電腦的選擇應該是隨機的。如果用戶沒有輸入正確的選項,會出現一個對話框,告訴用戶輸入一個有效的選項。這是我到目前爲止:在Java中使用JOptionPane的岩石紙剪刀遊戲
package assignment;
import java.util.Random;
import java.util.Scanner;
import javax.swing.*;
public class RockPaperScissorGame
{
public static void main(String[] args)
{
String inputStr;
String personPlay="";
String computerPlay="1,2,3";
int computerInt;
Scanner input = new Scanner(System.in);
Random generator = new Random();
inputStr = JOptionPane.showInputDialog("Lets play a game! \nEnter 1 for rock \nEnter 2 for paper \nEnter 3 for scissors \nEnter 4 to quit");
personPlay = input.next(inputStr);
switch (computerInt = 0)
{
}
do
{
if (personPlay.equals(computerPlay))
JOptionPane.showMessageDialog(null, "It's a TIE! ", "TIE!", JOptionPane.INFORMATION_MESSAGE);
else if (personPlay.equals("1"))
{
if (computerPlay.equals("3"))
JOptionPane.showMessageDialog(null, "Rock beats Scissors. \nYOU WIN! ", "YOU WIN!", JOptionPane.INFORMATION_MESSAGE);
else
JOptionPane.showMessageDialog(null, "Paper beats Rock. \nYOU LOSE! ", "YOU LOSE!", JOptionPane.INFORMATION_MESSAGE);
}
else if (personPlay.equals("2"))
{
if (computerPlay.equals("3"))
JOptionPane.showMessageDialog(null, "Scissor beats Paper. \nYOU LOSE!", "YOU LOSE!", JOptionPane.INFORMATION_MESSAGE);
else
JOptionPane.showMessageDialog(null, "Paper beats Rock. \nYOU WIN! ", "YOU WIN!", JOptionPane.INFORMATION_MESSAGE);
}
else if (personPlay.equals("3"))
{
if (computerPlay.equals("1"))
JOptionPane.showMessageDialog(null, "Scissor beats Paper. \nYOU WIN!", "YOU WIN!", JOptionPane.INFORMATION_MESSAGE);
else
JOptionPane.showMessageDialog(null, "Rock beats Scissors. \nYOU LOSE! ", "YOU LOSE!", JOptionPane.INFORMATION_MESSAGE);
}
else if (personPlay.equals("4"))
{
JOptionPane.showMessageDialog(null, "GOOD BYE", " BYE!", JOptionPane.INFORMATION_MESSAGE);
}
}while(true);
}
}
希望你們可以幫忙。謝謝:)
是'computerPlay'從「1,2,3」改變過? 'personPlay'會等於「1,2,3」嗎? –
