java如何执行cmd命令

请给详细代码，比如建个文件夹之类

Answer 1

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;

public class CommandTest {
public static void main(String args[]) {
String javaExcute="regedit";";//javaExcute为你要在CMD中执行的字符串

Process p;
try {
//执行CMD代码,返回一个Process
p = Runtime.getRuntime().exec(javaExcute);
InputStream is = p.getInputStream();
//得到相应的控制台输出信息
InputStreamReader bi = new InputStreamReader(is);
BufferedReader br = new BufferedReader(bi);
String message;
message = br.readLine();
while(message != null && !"".equals(message)){
//将信息输出
System.out.println(message);
message = br.readLine();
}
} catch (IOException e) {
e.printStackTrace();
return;
}
}
}

Answer 2

import java.io.*;
class exec
{
public static void main(String[] args)throws Exception{
Runtime exe = Runtime.getRuntime();
exe.exec("cmd");
Process p=exe.exec("java Test");
InputStream is = p.getInputStream();
int data;
while((data=is.read())!=-1){
System.out.print((char)data);
}

}
}
