Difference between dispose and exit on close in java
提问by Ayvadia
I have a single frame created using Netbeans GUI builder when I view the frame properties one of the first options is default close operation the options listed are: DISPOSE_ON_CLOSE, HIDE_ON_CLOSE, DO_NOTHING_ON_CLOSE& EXIT_ON_CLOSEI understand the middle two but, whats the difference between DISPOSE_ON_CLOSEand EXIT_ON_CLOSE? I have tried testing both but to me they do the same thing to me
当我查看框架属性时，我使用 Netbeans GUI 构建器创建了一个框架，其中第一个选项是默认关闭操作，列出的选项是：DISPOSE_ON_CLOSE, HIDE_ON_CLOSE, DO_NOTHING_ON_CLOSE&EXIT_ON_CLOSE我了解中间两个但是，DISPOSE_ON_CLOSE和之间有什么区别EXIT_ON_CLOSE？我试过测试两者，但对我来说他们对我做同样的事情

EXIT_ON_CLOSEwill terminate the program.
EXIT_ON_CLOSE将终止程序。
DISPOSE_ON_CLOSEwill call dispose()on the frame, which will make it disappear and remove the resources it is using. You cannot bring it back, unlike hiding it.
DISPOSE_ON_CLOSE将调用dispose()框架，这将使其消失并删除它正在使用的资源。你不能把它带回来，不像隐藏它。

If you have a few JFrames open and you close the one that is set to EXIT_ON_CLOSEthen all of the frames will be closed.
如果您打开了几个 JFrame 并关闭了设置为的一个，EXIT_ON_CLOSE则所有框架都将关闭。
The opposite applies to the one with the DISPOSE_ON_CLOSEi.e. only it will be closed
相反的情况适用于DISPOSE_ON_CLOSEie only 它会被关闭的那个
