cmd打开java文件夹_Java用CMD打开指定文件和文件夹

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!");

}

}

2、调用cmd打开目录

public class OpenDirectory {

public static void main(String[] args) throws IOException {

String[] cmd = new String[5];

String url = "D:\\ZTarget";

cmd[0] = "cmd";

cmd[1] = "/c";

cmd[2] = "start";

cmd[3] = " ";

cmd[4] = url;

Runtime.getRuntime().exec(cmd);

}

}

3、直接调用cmd命令

public static void main(String[] args) throws IOException {

String[] command = {"cmd","/c", "move G:/a.txt G:/Step_tmp.txt" };

Process ps = Runtime.getRuntime().exec(command );

}
