java 打开文件夹_JAVA_编程开发_程序员俱乐部

使用java 语言，如何打开文件夹和浏览文件呢？

打开文件夹或打开目录

class="java" name="code">/***
	 * 
	 * @param folder
	 *            : directory
	 */
	public static void open_directory(String folder) {
		File file = new File(folder);
		if (!file.exists()) {
			return;
		}
		Runtime runtime = null;
		try {
			runtime = Runtime.getRuntime();
			if (!SystemUtil.isWindows) {
				// System.out.println("is linux");
				runtime.exec("nautilus " + folder);
			} else {
				runtime.exec("cmd /c start explorer " + folder);
			}
		} catch (IOException ex) {
			ex.printStackTrace();
		} finally {
			if (null != runtime) {
				runtime.runFinalization();
			}
		}
	}

浏览文件：

/***
	 * 
	 * @param filePath
	 *            : only regular file
	 */
	public static void open_file(String filePath) {
		File file = new File(filePath);
		if (!file.exists()) {
			return;
		}
		Runtime runtime = null;
		try {
			runtime = Runtime.getRuntime();
			if (!SystemUtil.isWindows) {
				// System.out.println("is linux");
				runtime.exec("nautilus " + filePath);
			} else {
				runtime.exec("cmd /c start explorer /select,/e, " + filePath);
			}
		} catch (IOException ex) {
			ex.printStackTrace();
		} finally {
			if (null != runtime) {
				runtime.runFinalization();
			}
		}
	}

应用：

openFileButton.addActionListener(new ActionListener() {
			public void actionPerformed(ActionEvent e) {
				FileUtils.open_file(sourceTF.getText());				
			}
		});

openFolderButton = new JButton("打开文件夹");
		openFolderButton.addActionListener(new ActionListener() {
			public void actionPerformed(ActionEvent e) {
				//打开文件夹
				FileUtils.open_directory(targetTF.getText());
			}
		});
