在Java中，为什么人们用`this`前缀字段？ [英] In Java, why do people prepend fields with `this`?

问题描述

引用类变量时，为什么人们用 this 加上它？我不是在说这个用于消除方法参数的歧义，而是当它似乎不必要时。

示例：

  public class Person {
 private String name; 
 
 public String toString（）{
 return this.name; 
} 
} 
  

在 toString ，为什么不只是引用 name as name ？

$ b b

 返回名称; 
  

this.name / p>

这里 a相同的原因：

为什么有些人喜欢用m_或名称接口IFoo预先隐藏私有数据成员。他们认为它提高了可读性和清晰度。你是否同意这样的约定是一个品味的问题。

When referencing class variables, why do people prepend it with this? I'm not talking about the case when this is used to disambiguate from method parameters, but rather when it seems unnecessary.

Example:

public class Person {        
    private String name;

    public String toString() {
        return this.name;
    }
}

In toString, why not just reference name as name?

return name;

What does this.name buy?

Here's a stackoverflow question whose code has this pre-pending.

解决方案

Same reason why some people like to prepend private data members with "m_" or name interfaces "IFoo". They believe it increases readability and clarity. Whether or not you agree with conventions like these is a matter of taste.
