Eclipse - Generating Getters/Setters

Question

There is an option in Eclipse (Preferences -> Java->Code Style)

It allows "is" Prefix for getters if the return is boolean.

My question why does it not do the prefixing if the return is the wrapper class (Boolean) ?

Answer 1

This is simply because per the java beans specification/convention/implementation is prefix is only intended for primitive objects.

You can take a look at the PropertyDescriptor class source (getRealMethod):

 if (readMethodName == null) {
    Class type = getPropertyType0();
    if (type == boolean.class || type == null) {
        readMethodName = "is" + getBaseName();
    } else {
        readMethodName = "get" + getBaseName();
    }
    }

So eclipse is only conforming to this.

Edit: now why the property descriptor is made this way is another question, probably Java folks decided that the possibility of null return type and the "is" prefix may be misleading.
