我正在为学校制作一个充满词汇游戏的小街机。当我在 greenfoot 窗口中运行程序时，它运行良好。但是当我制作它的 jar 文件时，它会在使用 Greenfoot.ask() 提示时停止。这是代码：
import greenfoot.*;

import java.io.*;
import java.lang.*;

{
static ArrayList<World> back = new ArrayList<World>();

public static boolean run() throws IOException
{

Collections.shuffle(problems);
for(int x = 0; x < 3; x++)
{
String[] def = answers.get(problems.get(x)).split(" ");
String answer = Greenfoot.ask("What does " + problems.get(x) + " mean?");
count = 0;
for(String temp: def)
{
if(answer.contains(temp))
count++;
}
if(count > def.length/2 && count > 1 || count == def.length)
{
help.showText("Correct",300,100);
Greenfoot.delay(50);
right++;

{
help.showText("Actually... it means " + answers.get(problems.get(x)), 300, 100);
Greenfoot.delay(50);
}
if(right >= 2)
{

}

}

如果您需要整个项目，请告诉我，我会分享。
