Online Banking system window version

Recently doing is the window version of the online banking system, before this altogether made two versions, the first is more sketchy, the second version on the basis of the first added map collection, now do this in the map set based on the implementation of the windowing. In the process of self-study window, I think the serial port is quite simple, that is, some methods, but really to use the time to find a lot of new problems, such as with what, using the layout manager is more appropriate? Finally, my choice is to cancel the layout manager, because I think the cancellation of the layout manager, the interface free control system is higher, but this increases the workload, because you have to set the location for each component, constantly adjust, to do the most beautiful. There is also found that the textbook on the knowledge is not enough, encountered many problems, such as the addition of the component is add, then the deletion method of the component? The textbook does not say, there is in the program execution, if the interface components have been modified, such as mobile location, add delete and so on .... But there is Baidu, so it is hard to live with me. For example, the removal method of the component is remove, the interface can be updated with w2.setvisible (false); W2.setvisible (True);(here the W2 is an interface).

All in all, by doing this, a lot has been harvested. Understand a truth-----------to the end of the paper, it must be preach.
