java图形界面中定义一个“浏览”按钮，点击可以打开选择文件的对话框

[Elvis_欧元_]

如图，如图在java图形界面中定义一个“浏览”按钮，点击可以打开选择文件的对话框，而且选择文件确定后可以把文件路径打印到textField中。具体要怎么写？

JFileChooser fc = new JFileChooser();
...
public void actionPerformed(ActionEvent e) {
//Handle open button action.
if (e.getSource() == openButton) {
int returnVal = fc.showOpenDialog(FileChooserDemo.this);

if (returnVal == JFileChooser.APPROVE_OPTION) {
File file = fc.getSelectedFile();
//This is where a real application would open the file.
log.append("Opening: " + file.getName() + "." + newline);
} else {
log.append("Open command cancelled by user." + newline);
}
} ...
}
