I read this statement from core java - cays - sun microsystems book .

interface can't have instance field & implemented method .

implemented method is OK but what is the meaning of instance field .

thanks in advance .

unless i'm badly mistaken, an "implemented field" is to variables what an "instance method" is to a procedure / code snippet. that is, a variable that wouldn't be considered fully virtual, one that would be instantiated if the class were to be instantiated. i might be wrong, though.

an instance field is a non-static variable

interface variables are always static, final, and public. These modifiers can be used but are unnecessary.
