java docs, beginner question

[amber vessel]

A beginner's question about javadocs: the interface "Queue" has descriptions of his methods what the methods can do, but the methods of an interface have no method body, so the methods can't do anything. Why then are there descriptions of what the methods can do?

Because the intention of the Queue interface remains the same for all implementations. Different implementations have changes internally but the base functionality remains the same

interfaces are contracts

any implementation will have to follow it
