我对if语句有一个奇怪的问题.我正在检查布尔值是否为true，是否必须运行if语句.我在很多地方都使用System.out.println布尔值，其值始终为false，但if语句仍在运行.有帮助吗?

I have a strange problem with an if statement. I'm checking if a Boolean is true, if it is the if statement must run. I System.out.println the value of the boolean at a lot of places, its always false but the if statement still runs. Any help ?

import java.util.ArrayList; public class GameLoop extends Thread { private Boolean running; private ArrayList<Meteor> meteorArrayList; private Boolean win; private GameScreen gameScreen; public GameLoop(GameScreen gameScreen, ArrayList<Meteor> meteorArrayList) { setMeteorArrayList(meteorArrayList); setGameScreen(gameScreen); setRunning(true); setWin(false); } @Override public void run() { while (running) { if(checkWin()); { System.out.println(checkWin()); gameScreen.winGame(); } } } public Boolean checkWin() { if(getMeteorArrayList().isEmpty()) { setWin(true); } else { setWin(false); } System.out.println(getWin()); return getWin(); } public void cancel() { interrupt(); } //======================GETTER EN SETTERS============================= public Boolean getRunning() { return running; } public void setRunning(Boolean running) { this.running = running; } public ArrayList<Meteor> getMeteorArrayList() { return meteorArrayList; } public void setMeteorArrayList(ArrayList<Meteor> meteorArrayList) { this.meteorArrayList = meteorArrayList; } public Boolean getWin() { return win; } public void setWin(Boolean win) { this.win = win; } public GameScreen getGameScreen() { return gameScreen; } public void setGameScreen(GameScreen gameScreen) { this.gameScreen = gameScreen; }

}

推荐答案

在该行代码中有一个小的语法错误.

You have a small syntax error in that line of code.

代替

if (checkWin());

应该是

if (checkWin())
