java如何关闭运行的进程_用java查看有没有运行进程，或者关闭进程

查看是否有在运行cmd.exe，代码如下

import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStreamReader;

import java.util.Scanner;

public class Main {

/**

* @param args

*/

public static void main(String[] args) {

boolean isrun=isRunning("cmd.exe");

if(isrun){

System.out.println("有在运行cmd.exe");

}else{

System.out.println("没有运行cmd.exe");

}

}

public static boolean isRunning(String processName)//判断有没有在运行考试软件

{

BufferedReader bufferedReader = null;

try

{

Process proc = Runtime.getRuntime().exec("tasklist /FI "IMAGENAME eq "

+ processName

+ """);

bufferedReader = new BufferedReader(new InputStreamReader(proc.getInputStream()));

String line = null;

while ((line = bufferedReader.readLine()) != null)

{

if (line.contains(processName)) //判断是否存在

{

return true;

}

}

return false;

}

catch (Exception ex)

{

ex.printStackTrace();

return false;

}

finally

{

if (bufferedReader != null)

{

try

{

bufferedReader.close();

}

catch (Exception ex)

{

}

}

}

}

}

关闭cmd.exe

Runtime.getRuntime().exec("taskkill /f /im cmd.exe");
