推荐答案

您可以在 Java 程序中运行以下语句.在此之前，您需要知道任务管理器中的任务名称.假设您想查看 MS-Word 正在运行.然后运行 ​​MS-Word，进入任务管理器，在进程选项卡下，您应该看到一个名为 word.exe 的进程.找出您所针对的流程的名称.完成后，您只需运行以下代码:

You can run the following statement in your java program. Before that you need to know the name of the task in task manager. Say you want to see MS-Word is running. Then run MS-Word, go to task manager and under the process tab, you should see a process named word.exe. Figure out the name for the process you are targeting. Once you have that, you just run the following code:

String line;
String pidInfo ="";

Process p =Runtime.getRuntime().exec(System.getenv("windir") +"\system32\"+"tasklist.exe");

BufferedReader input =  new BufferedReader(new InputStreamReader(p.getInputStream()));

while ((line = input.readLine()) != null) {
    pidInfo+=line; 
}

input.close();

if(pidInfo.contains("your process name"))
{
    // do what you want
}
