java执行命令并获得命令执行结果，java执行命令,比如运行cmd 到Con

比如运行cmd 到Console,然后执行java -version命令,会获取JDK信息,我要是想获取JDK的这些信息,保存到String,输出出来:

import java.io.*;public class Test{  public static void main(String [] args)  {    try    {      Process pro = Runtime.getRuntime().exec("cmd /c java -version");       BufferedReader br = new BufferedReader(pro.getInputStream());      String msg = null;      while((msg = br.readLine())! = null){        System.out.println(msg);      }    }    catch(IOException exception)    {    }    catch(InterruptedException exception2)    {    }  }}
