Java JFileChooser 使用方法

一、JFileChooser作为路径选择器

import javax.swing.JFileChooser;
import javax.swing.UIManager;
import javax.swing.UnsupportedLookAndFeelException;

public class JFileChooserTest {
	public static void main(String[] args) throws ClassNotFoundException,
			InstantiationException, IllegalAccessException,
			UnsupportedLookAndFeelException {
		String path = null;
		//设置界面风格
		UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
		JFileChooser jdir = new JFileChooser();
		//设置选择路径模式
		jdir.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
		//设置对话框标题
		jdir.setDialogTitle("请选择路径");
		if (JFileChooser.APPROVE_OPTION == jdir.showOpenDialog(null)) {//用户点击了确定
			path = jdir.getSelectedFile().getAbsolutePath();//取得路径选择
		}
		System.out.println(path);
	}
}
