Auto create constructor body and fields in Netbeans based on signature
提问by assylias
If I start from an empty class (TestClass) in Netbeans and add the following empty constructor:
如果我从 Netbeans 中的一个空类 (TestClass) 开始并添加以下空构造函数：
public void TestClass(String a, String b) {
}
is there a way to have netbeans automagically generate:
有没有办法让 netbeans 自动生成：
private final String a;
private final String b;
public void TestClass(String a, String b) {
this.a = a;
this.b = b;
}
I know that I can first create the 2 members and ask netbeans to auto-generate the constructor but I'm asking for the other way round.
我知道我可以先创建 2 个成员并要求 netbeans 自动生成构造函数，但我要求反过来。
For example, in eclipse, this can be achieved by pressing CTRL+1on the constructor's argument > assign parameter to new field.
例如，在 eclipse 中，这可以通过在构造函数的参数上按CTRL+ 1> 将参数分配给新字段来实现。

You can write the empty constructor with the required signature. Then set the cursor next to a parameter and press Alt+ENTER.
您可以使用所需的签名编写空构造函数。然后将光标设置在参数旁边并按 Alt+ENTER。
NetBeans will ask to create a new field. Press ENTER and NetBeans will write the code for you.
NetBeans 将要求创建一个新字段。按 ENTER 键，NetBeans 将为您编写代码。
I think you have to do it for each parameter separately, but I'm not sure.
我认为您必须分别为每个参数执行此操作，但我不确定。
Generally, Alt+ENTER in NetBeans is similar to Ctrl+1 in Eclipse, also at other places.
一般来说，NetBeans 中的 Alt+ENTER 类似于 Eclipse 中的 Ctrl+1，其他地方也一样。

Just point the cursor at the point where you want the generated code to appear, and press Alt + Insert (or select Source -> Insert Code). The following menu will appear, where you can choose to generate whatever you want:
只需将光标指向您希望生成的代码出现的位置，然后按 Alt + Insert（或选择 Source -> Insert Code）。将出现以下菜单，您可以在其中选择生成任何您想要的内容：
