java 中调用window系统中的文件,或者执行命令（shell、.CMD、.EXE）并获取返回值(如果有的话)

import java.io.BufferedInputStream;

import java.io.IOException;

public class Test {

/**

* @param args

*/

String name2 = "C:/test.cmd";//我CMD里面的内容是 netstat -ano 其他的也可以

String name3 = "java -version";

try {

System.out.println(execCMD(name1, 3));

System.out.println(execCMD(name2, 2));

System.out.println(execCMD(name3, 1));

} catch (IOException e) {

e.printStackTrace();

}

}

/**
