I am trying to find out how to close a particular external exe namely cwserv5.exe. I have succeeded in starting a new external exe and closing it .But not an existing process. Can you help? Below is what I was tinkering with but really lost to be honest
我试图找出如何关闭特定的外部 exe，即 cwserv5.exe。我已成功启动一个新的外部 exe 并关闭它。但不是现有进程。你能帮我吗？下面是我正在修补的内容，但说实话真的输了
package com.TestCase;
import java.io.BufferedReader;
import java.io.InputStreamReader;
public class ReStartEXE {
static Process pr;
public static void open() {
//ProcessBuilder
try {
Runtime rt = Runtime.getRuntime();
//Process pr = rt.exec("cmd /c dir");
pr = rt.exec("C:\APPLEGREEN\webserv\cwserv5rost.exe");
Thread.sleep(10000);
//pr.wait(10000);
//pr.waitFor();
BufferedReader input = new BufferedReader(new InputStreamReader(pr.getInputStream()));
// String line=null;
/*while((line=input.readLine()) != null) {
System.out.println(line);
}*/
//int exitVal = pr.waitFor();
//pr.destroy();
// Process.kill(pr);
// Runtime.getRuntime().exec("taskkill /F /IM cwserv5rost.exe");
//System.out.println("Exited with error code "+exitVal);
} catch(Exception e) {
System.out.println(e.toString());
e.printStackTrace();
}
}
public static void Close() {
pr.destroy();
}
}

You can do this by executing a process to close the process that you want to close.
您可以通过执行一个进程来关闭要关闭的进程来完成此操作。
In your comments I can see taskkill, which means that you're probably using Windows.
在您的评论中，我可以看到taskkill，这意味着您可能正在使用 Windows。
Runtime rt = Runtime.getRuntime();
rt.exec("taskkill /F /IM cwserv5.exe");
This will force the process with image name cwserv5.exeto end.
这将强制cwserv5.exe结束带有图像名称的进程。
If you don't want to force it to end, don't use the /ftag.
如果您不想强制结束，请不要使用该/f标签。
For more information on taskkill, go to cmd(command prompt) and type taskkill /?.
有关 的更多信息taskkill，请转到cmd（命令提示符）并键入taskkill /?。

try this,
试试这个，
Process proc = rt.exec("taskkill /F /IM cwserv5.exe");
BufferedReader input = new BufferedReader(new InputStreamReader(proc.getInputStream()));
while ((line = input.readLine()) != null){
//do something
}
input.close();
code = proc.exitValue();
if(code==0){
//success
}
else{
//failure
}
