Javaで指定したexeファイルを開く方法

 
	public static void main(final String[] args) throws IOException {
		openWindowsExe();
		openExe();
		openFile();
	}
 
	// 用 Java 调用windows系统的exe文件，比如notepad，calc之类
	public static void openWindowsExe() {
		final Runtime runtime = Runtime.getRuntime();
		Process process = null;
		try {
			final String command = "notepad";// 记事本
			process = runtime.exec(command);
		} catch (final Exception e) {
			System.out.println("Error win exec!");
		}
	}
 
	// 调用其他的可执行文件，例如：自己制作的exe，或是 下载 安装的软件.
	public static void openExe() {
		final Runtime runtime = Runtime.getRuntime();
		Process process = null;
 
		try {
			process = runtime.exec("C:\\Program Files\\Notepad++\\notepad++.exe");
 
		} catch (final Exception e) {
			System.out.println("Error exec!");
		}
	}
 
	// 打开其他任意格式的文件，比如txt,word等
	public static void openFile() {
		final Runtime runtime = Runtime.getRuntime();
		Process process = null;//
		final String cmd = "rundll32 url.dll FileProtocolHandler file://F:\\ECT项目资料\\建立EMF工程.txt";
		try {
			process = runtime.exec(cmd);
		} catch (final Exception e) {
			System.out.println("Error exec!");
		}
