我已经被要求创建一个我选择的星球大战主题游戏，必须使用JOptionPane而不是控制台来玩。我设置主菜单和基本的东西很好，但其余的我不知道该怎么做。
我的游戏是战舰游戏，到目前为止它在控制台中运行，但是我不知道该怎么做才是网格工作。游戏必须以电影中的BB-8角色为特色。我的代码在这里：
import java.util.*;
import javax.swing.*;
public class BattleShips {
public static void main(String[] args) {
Scanner a = new Scanner (System.in);
System.out.print("Welcome To Battleships!\n\nSelect One Of The Following Options:\n\n1. Play\n2. How To Play\n3. Exit\n\n");
String choice = a.nextLine();
if(choice.equals("2")){
System.out.print("\nThe rules of battleships are simple."
+ "\n\n- Your aim is to destroy all enemy ships, the first to destoy all opposing ships first wins."
+ "\n- You will have 4 ships all of which are 3 spaces long."
+ "\n- You will have the choice of placing your ships anywhere you wish, "
+ "simply by deciding if you want it vertical or horizontal and entering the centre coordinate."
+ "\n- You will then have to guess where the enemy ships are and enter the coordinates, "
+ "if you hit the enemy ships you will recieve points."
+ "\n- If your ships are hit, you will lose a point.");

答案 0 :(得分：1)
要使用JOptionPane使用来接收用户的输入：
String inputString = JOptionPane.showInputDialog(null, "Enter input");
您只需将scanner.nextXXX()替换为该行即可。
注意：如果用户按下null上的X按钮，结果可能是JOptionPane，您应该检查这样：
String inputString = JOptionPane.showInputDialog(null, "Enter input");
if(inputString!=null){
//and then use the inputString
...
}
