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_CLOSE I understand the middle two but, whats the difference between DISPOSE_ON_CLOSE and EXIT_ON_CLOSE ? I have tried testing both but to me they do the same thing to me

推荐答案

EXIT_ON_CLOSE 将终止该程序。

DISPOSE_ON_CLOSE 将调用 dispose（）在框架上，这将使它消失并删除它正在使用的资源。与隐藏它不同，你不能把它带回去。

DISPOSE_ON_CLOSE will 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.
