Question

求java大神告知这个程序是在回答正确是进入下一题，怎么改在回答错误时也进入下一题，且分数不变。

import java.io.*;import java.awt.*;import java.awt.event.*;import javax.swing.*;
public class StandardExamInTime extends JFrame implements ActionListener,ItemListener{File testFile;int MAX=8;int maxTime=MAX,score=0;
javax.swing.Timer time; //计时器
JTextArea showQuesion; //显示试题
JCheckBox choiceA,choiceB,choiceC,choiceD;JLabel showScore,showTime;
String correctAnswer; //正确答案

public void itemStateChanged(ItemEvent e) {
		JCheckBox box = (JCheckBox) e.getSource();
		String str = box.getText();
		boolean booOne = box.isSelected();
		boolean booTwo = str.compareToIgnoreCase(correctAnswer) == 0;
		if (booOne) {
			if(booTwo){
				score++;
			}
			showScore.setText("分数：" + score);
			time.stop(); // 停止计时
			maxTime = MAX;
			readOneQuesion(); // 进入下一道题目
		}

		box.setSelected(false);
