NetBeans中用界面设计器通过拖动控件构成界面的代码，能用到eclipse中吗？

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：

Java code

[解决办法]
jButton1.setText("1");
就是
JButton b=new JButton();
b.setText("1");
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");
