我正在尝试为我们的主题解决这个任务。我已经在不使用的情况下尝试过它JOptionPane
并且它有效,但是当我将它编辑为有一个对话框时,它没有用。第一个对话框应该包含一个标题和要输入的选项,最后一个应该允许用户退出程序。用户输入他/她的选择后,应出现一个对话框,指示用户的选择和计算机的选择。计算机的选择应该是随机的。如果用户没有输入正确的选项,则会出现一个对话框,告诉用户输入有效的选项。这是我到目前为止所拥有的:
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);
}
}
希望大家能帮忙。谢谢 :)
