生成失败（总时间：0 秒）
这个是什么问题啊 谢谢！！
附源码：

public void saveFile()
{
fileChooser=new JFileChooser();
fileChooser.setFileSelectionMode(JFileChooser.FILES_ONLY);
int result=fileChooser.showSaveDialog(this);
if(result==JFileChooser.CANCEL_OPTION);
return;
File fileName = fileChooser.getSelectedFile(); fileName.canWrite();
if(fileName==null||fileName.getName().equals(""))
JOptionPane.showMessageDialog(fileChooser,"Invalid File Name",
"Invalid File Name",JOptionPane.ERROR_MESSAGE);
else{
try{
fileName.delete();
FileOutputStream fos=new FileOutputStream(fileName);
output=new ObjectOutputStream(fos);
drawings record;
output.writeInt(index);

for(int i=0;i<index;i++)
{
drawings p=itemList[i];
output.writeObject(p);
output.flush();
}
output.close();
fos.close();
}
catch(IOException ioe)
{
ioe.printStackTrace();

}
}

}

if(result==JFileChooser.CANCEL_OPTION); //这里多了个分号，把他去掉
return;
File fileName = fileChooser.getSelectedFile();
fileName.canWrite();

return语句下面不能写代码了

[cangyue87]

程序执行到return之后就会向上一级返回,也就是说会返回到调用saveFile() 的那个方法去...

这样看saveFile()方法中有永远也执行不到的语句...

老兄有几处错误哦,你用我的与你自己的比较一下吧:

    public void saveFile()
    {
        fileChooser = new JFileChooser();
        fileChooser.setFileSelectionMode(JFileChooser.FILES_ONLY);
        int result = fileChooser.showSaveDialog(this);
        if (result == JFileChooser.CANCEL_OPTION) {
            return;
        }
        else {
            File fileName = fileChooser.getSelectedFile();
            fileName.canWrite();
            if (fileName == null || fileName.getName().equals("")) {
                JOptionPane.showMessageDialog(fileChooser, "Invalid   File   Name",
                                              "Invalid   File   Name", JOptionPane.ERROR_MESSAGE);
            }
            else {
                try {
                    fileName.delete();
                    FileOutputStream fos = new FileOutputStream(fileName);
                    output = new ObjectOutputStream(fos);
                    drawings record;
                    output.writeInt(index);

                    for (int i = 0; i < index; i++) {
                        drawings p = itemList[i];
                        output.writeObject(p);
                        output.flush();
                    }
                    output.close();
                    fos.close();
                }
                catch (IOException ioe) {
                    ioe.printStackTrace();

                }
            }
        }
    }

好好看看吧,你怎么if后面都不加这个呀{},写java代码的大忌哦!
