布尔变量名的Java命名约定：writerEnabled vs writerIsEnabled

问题描述

以下哪些声明符合Java的命名约定？

Which of the following declarations conforms to Java's naming conventions?

private boolean writerIsEnabled;
// with methods like
public boolean getWriterIsEnabled()
public void setWriterIsEnabled()

OR

private boolean writerEnabled;
// with methods like
public boolean getWriterEnabled()
public void setWriterEnabled()

我个人觉得第一个名字writerIsEnabled更具可读性，特别是当你在if语句中使用它时 -

I personally find the first name "writerIsEnabled" to be more readable, especially when you use it in an if statement like this -

if(writerIsEnabled)
 {
    //...
 }

推荐答案

据我所知，就是这样：

private boolean writerEnabled;
// with methods like
public boolean isWriterEnabled();
public void setWriterEnabled(boolean enabled);

当类型为 boolean 或 Boolean ，区别在于Getter以开头是而不是 get 。

Either when the type is boolean or Boolean, the difference is that the Getter starts with is instead of get.

我个人更喜欢 isWriterEnabled 方法。例如，JSF等技术在访问属性时尊重该标准。 EL表达式通过 和获取进行确认。

Personally I prefer the isWriterEnabled approach. Technologies like, for example, JSF respect that standard when accessing properties. The EL expressions are acknowledged with is and get.
