java执行命令(cmd,shell)
一个简单的小工具，用java执行系统命令，并打印输出。public class OSExecute {/** * <b>command。</b> * <p> * <b>详细说明：</b> * </p> * <!-- 在此添加详细说明 --> 无。 ** @param command */public static void command(String command) {try {Process process = new ProcessBuilder(Arrays.asList(command.split(" "))).start();// 标准输入流BufferedReader result = new BufferedReader(new InputStreamReader(process.getInputStream()));String s = result.readLine();while (s != null) {System.out.println(s);s = result.readLine();}// 标准错误输入流BufferedReader error = new BufferedReader(new InputStreamReader(process.getErrorStream()));s = error.readLine();while (s != null) {System.err.println(s);s = error.readLine();}} catch (Exception e) {// 纠正if (!command.startsWith("CMD /C")) {command("CMD /C " + command);} else {throw new RuntimeException(e.getMessage());}}}public static void main(String[] args) {OSExecute.command("dir");}} 测试ls（windows下测试）,命令的结果：
