博主在进行小型项目开发时遇到问题，每次运行程序都会产生新的Java进程，导致延迟和性能下降。任务管理器显示多个'Javaw.exe'实例。在调试模式下发现每次运行同一项目都会启动新实例。目前的临时解决方案是手动从调试区结束这些进程。博主希望找到方法避免重复创建实例，只需一个可以重复使用的实例。文章提到关闭应用程序的正确方式是通过主框架的关闭按钮，而不是直接杀死进程，因为这可能会影响资源的正常关闭。

I was doing a small project and everytime I run the program, I can feel more lag and delay, until it is completely not working anymore.

I checked with the task managers and found many "Javaw.exe" Instances. Then I opened the debug field and realize that it runs a new instance everytime I run the same project.

here is the link to image of the instances in debug area.

The temporary solution for me is to terminate them from the debug area. Is there any way to prevent the same project from creating a new instance everytime it is run ? I only need one instance that can be reused everytime I run again and again.

Thanks for any response in advance.

No, I'm sure that's not what you want. If you restart an application, it's probably that you want to test some changes you've just made in the code. So Eclipse needs to start a new instance of your application. You could also want to start two instances of an app because they need to talk to each other.

If you want previously launched applications to stop, then stop them. Your app seems to be a GUI app. Use the close button on the main frame of the app to close it. As simple as that.

It's often not desired to kill an application, because it might need to properly close resources, or tell the server it's leaving before exiting, or whatever. Having Eclipse kill apps without a conscious request from the user would not be wise.
