Java naming convention for boolean variable names: writerEnabled vs writerIsEnabled(布尔变量名称的 Java 命名约定:writerEnabled 与 writerIsEnabled)

本文介绍了布尔变量名称的 Java 命名约定:writerEnabled 与 writerIsEnabled的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

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()

或

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

我个人认为名字writerIsEnabled"更具可读性，尤其是当您在这样的 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

据我所知是这样的:

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

无论类型是boolean还是Boolean，区别在于Getter以is开头，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，像 JSF 这样的技术在访问属性时尊重该标准.EL 表达式用 is 和 get 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.
