发现用 NetBeans中用界面设计器生成的文件中,除了一个.java文件,还有一个.form文件但java文件中的代码比较乱呀,在eclipse中就是几行便可以写出这几个按钮呀不知,这样乱的源码能否在eclipse中直接用?据说NetBeans不是开源的,用NetBeans中用界面设计器生成的源码别的编译器没法用,不知是否是这么回事实例:/*

我没用过NetBeans 查API就可以了,NetBeans就可以了,他只不过用java的API写的代码,连封装都没有封装。
只要你没看见他导入别的包,就去API找什么意思。不会凭空捏造出来的。
setActionCommand(String command)
设置此按钮激发的动作事件的命令名称。
默认的ActionCommand 应该是"1",设置这个之后就变成"jButton1"
jButton1.setActionCommand("jButton1");
jButton1.setText("A");
但我想问的就是,我让它叫jButton1就不行吗??
还是ActionCommand?
jButton1 是新建的一个JButton的一个实例的名字。貌似netbeans自动管理的,不让手动指定名称
