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.
