Java 执行 cmd 命令

方法

Runtime.getRuntime().exec("这里是cmd命令")

例子

关闭 wps.exe 进程，以下是完整写法，如果只执行 exec()方法有时会卡住

	@Test
	public void closeProgress() {
		try {
			Process process = Runtime.getRuntime().exec("taskkill /f /im wps.exe");
			InputStream errorStream = process.getErrorStream();  
			InputStreamReader reader = new InputStreamReader(errorStream);  
			BufferedReader bufferedReader = new BufferedReader(reader);  
			String line;  
			while ((line = bufferedReader.readLine()) != null) {
				System.out.println(line);
			}  
			process.waitFor(); // 等待进程结束
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
