cmd实现java_使用java实现cmd操作

使用java实现编写一个bat脚本，并运行该脚本。该脚本实现自动编译并运行java文件

import java.io.BufferedWriter;

import java.io.File;

import java.io.FileOutputStream;

import java.io.OutputStreamWriter;

/**

public class CmdTest {

public static void main(String[] args) {

Runtime rt = Runtime.getRuntime();

try {

File file = new File(“D:\\2017\\test\\Test.bat”);

if(file.exists()){

file.delete();

}

file.createNewFile();

BufferedWriter bw = new BufferedWriter(

new OutputStreamWriter(

new FileOutputStream(file), “UTF-8”));

bw.write(“D:”);

bw.newLine();

bw.write(“cd ./2017/Test”);

bw.newLine();

bw.write(“javac Test.java”);

bw.newLine();

bw.write(“timeout 3”);

bw.newLine();

bw.write(“java Test”);

bw.newLine();

bw.write(“pause”);

bw.close();

rt.exec(“cmd /c start D:\\2017\\Test\\Test.bat”);//实现打开cmd执行脚本

//System.out.println(“结果：”+rt.exec(“cmd D:\\2017\\Test\\Test.bat”).toString());

} catch (Exception e){

System.out.println(“错误：”+e);

}

}

}
