What do the icons in Eclipse mean?
In the "Package Explorer" in the Eclipse IDE, I can click on a Java class and list all its methods. The methods are displayed with a few different icons before the name, including a green circle or a red square.
What do these icons mean? Is there a webpage that explains them?
回答1:
Green circle indicates a public method
Red square indicates a private method
Yellow diamond indicates a protected method
Blue triangle indicates default (package visible) method
This page gives an overview of all the icons used in Eclipse JDT. This page explains what the different access levels mean in Java terms, in case you aren't familiar with that.
回答2:
Methods with the red square are private and the ones with the green circle are public.
