eclipse警告“字段声明隐藏另一个字段或变量"的用法? [英] Usage of eclipse warning "field declaration hides another field or variable"?

问题描述

Eclipse 有一个名为的 java 编译器设置字段声明隐藏了另一个字段或变量"，可以设置为警告/错误.

Eclipse has a java compiler setting called "field declaration hides another field or variable" that can be set to warning/error.

您认为此警告有多重要?

How important is this warning in your opinion?

处理这个问题的好的标准方法是什么?

What is a good standard way to handle this problem?

发生这种情况的代码示例:

Code example of where this happens:

public class Test {
   private String caption = null;

   public Test(String caption) { // here
     this.caption = caption;
   }
}

我见过重命名字段的解决方案，即fCaption"，但这会导致可以生成的自动 getter/setter 具有奇怪的名称(getfCaption()).不是不可读，而是丑陋...

I've seen solutions where the field is renamed, i.e "fCaption", but that would cause the automatic getters/setters that can be genereated to have odd names (getfCaption()). Not unreadable, but ugly...

哦，是的，有可能重命名方法签名 Test(String caption_) 或类似的东西，但这最终会在 javadoc 中看起来很奇怪.

Oh yea, there is the possibility to rename the method signature Test(String caption_) or something similar, but that would end up in the javadoc looking weird.

推荐答案

在我看来，这是一个非常有用的选项，应该启用以显示编译器警告.有一个选项(在我的版本中至少是 Eclipse 3.5.2，Java EE 功能 1.2.2)可以在构造函数和 getter/setter 中进一步启用/禁用它以防止误报.

This is a very useful option in my opinion and should be enabled to show a compiler warning. There is an option (in my version at least Eclipse 3.5.2, Java EE feature 1.2.2) to further enable/disable it within constructors and getters/setters to prevent false positives.
