Java调用CMD命令行获取输出

 

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");        /*      pro.waitFor(); InputStream out = pro.getInputStream(); int i; while ((i = out.read()) != -1) { System.out.println((char) i); } */ BufferedReader br = new BufferedReader(pro.getInputStream()); String msg = null; while((msg = br.readLine())! = null){ System.out.println(msg); } } catch(IOException exception) { } catch(InterruptedException exception2) { } } }
