Java用CMD打开指定文件和文件夹_一天不进步，就是退步._java打开文件命令

1、打开可执行程序(exe等)

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!");  
    }  
}  public static void main
