我正在创建一个 java 程序,它为大奖赛/松木德比之类的比赛创建阵容,然后一旦输入分数,就会找到决赛选手并为他们分配一个车道/热号。
到目前为止,程序中的所有内容都完全按照我的意愿进行,直到我到达我试图创建决赛选手的部分。在我单击按钮/按 Enter 输入最终分数后,我的 GUI 冻结。这是冻结之前的代码:
//allows user to enter the places for each car in each heat in each round
void enterScores() {
if(indexCount == 0 || (indexCount) % numLanes == 0) {
textArea.append("\nRound " + (roundCount + 1) + " Heat " + (heatCount+1) + ": ");
}
userResponse.setText("");
prompt.setText(holderNameArray[roundCount][indexCount] + ": ");
textArea.append("\n" + holderNameArray[roundCount][indexCount] + ": ");
userResponse.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
holderScoreArray[roundCount][indexCount] = Integer.parseInt(userResponse.getText());
textArea.append("" + holderScoreArray[roundCount][indexCount]);
indexCount++;
for(ActionListener act : enter.getActionListeners()) {
enter.removeActionListener(act);
}
for(ActionListener act : userResponse.getActionListeners()) {
userResponse.removeActionListener(act);
}
repeatEnterScores();
}
});
enter.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
holderScoreArray[roundCount][indexCount] = Integer.parseInt(userResponse.getText());
textArea.append("" + holderScoreArray[roundCount][indexCount]);
indexCount++;
for(ActionListener act : enter.getActionListeners()) {
enter.removeActionListener(act);
}
for(ActionListener act : userResponse.getActionListeners()) {
userResponse.removeActionListener(act);
}
repeatEnterScores();
}
});
}
//helps repeat enterScores() due to anon class restrictions
//checks to change the number of heats/rounds
void repeatEnterScores() {
if((indexCount) % numLanes == 0 || indexCount == numCars) {
heatCount++;
}
if(indexCount == numCars) {
indexCount = 0;
heatCount = 0;
roundCount++;
}
if(roundCount < numRounds) {
enterScores();
} else {
textArea.setText("You may now click the Scores tab to see the scores you have just entered.");
scoresPanelSetup();
}
}
它过去不会冻结并继续,而是会在以后的地方冻结。我是初学者,所以我不确定为什么现在这里会结冰。如果您需要更多代码/信息,请告诉我。每当我调试它时,我的所有代码都很好,只是 gui 有问题。
谢谢!
