java yes

java yes

我创建了一个JOptionPane，它只有两个按钮YES_NO_OPTION。

JOptionPane.showConfirmDialog弹出后，我想单击YES BUTTON继续打开JFileChooser，如果我单击否按钮，它应该取消操作。

这看起来很容易，但我不知道我的错误在哪里。

代码段：

LineCount() >= 1){ //The condition to show the dialog if there is text inside the textArea

int dialogButton = JOptionPane.YES_NO_OPTION;

JOptionPane.showConfirmDialog (null, "Would You Like to Save your Previous Note First?","Warning",dialogButton);

if(dialogButton == JOptionPane.YES_OPTION){ //The ISSUE is here

JFileChooser saveFile = new JFileChooser();

int saveOption = saveFile.showSaveDialog(frame);

if(saveOption == JFileChooser.APPROVE_OPTION){

try{

BufferedWriter fileWriter = new BufferedWriter(new SelectedFile().getPath()));

fileWriter.Text());

fileWriter.close();

}catch(Exception ex){

}

}
