我可以通过构造函数在eclipse中自动生成字段吗？ [英] Can I generate fields automatically in eclipse from a constructor?

问题描述

当我在Eclipse中进行编码时，我希望尽可能地懒惰。因此，我经常键入类似的内容：

When I'm coding in eclipse, I like to be as lazy as possible. So I frequently type something like:

myObject = new MyClass（myParam1，myParam2，myParam3）;

myObject = new MyClass(myParam1, myParam2, myParam3);

Even尽管MyClass不存在，它也不是构造函数。几次单击之后，eclipse用从我键入的内容推断出的构造函数创建了MyClass。我的问题是，是否也可以使eclipse生成类中与我传递给构造函数相对应的字段？我意识到这是超级懒惰，但这就是日食的全部乐趣！

Even though MyClass doesn't exist and neither does it's constructor. A few clicks later and eclipse has created MyClass with a constructor inferred from what I typed. My question is, is it possible to also get eclipse to generate fields in the class which correspond to what I passed to the constructor? I realize it's super lazy, but that's the whole joy of eclipse!

推荐答案

如果您有A类。

class A{
    A(int a |){}
}

|是光标。 Crtl + 1 将参数分配给新字段

结果：

class A{
    private final int a;
    A(int a){
        this.a = a;
    }
}

此方法也适用于方法：

    void method(int b){}

将导致：

    private int b;
    void method(int b){
        this.b = b;

    }
