如何用java執(zhí)行命令行？

Java運行命令行并獲取返回值，下面以簡單的Java執(zhí)行ping命令（ping127.0.0.1-t）為例，代碼如下：Process p = Runtime.getRuntime().exec("ping 127.0.0.1 -t")Process p = Runtime.getRuntime().exec("javac")InputStream is = p.getInputStream()BufferedReader reader = new BufferedReader(new InputStreamReader(is))String linewhile((line = reader.readLine())!= null){ System.out.println(line) }p.waitFor()is.close()reader.close()p.destroy()}
