RE: Comparing Collections



fixed

Hey Thorbjørn

Have you considered using Test Driven Design to write such a library?

Can you post some links to sites that describe these design principles?

int c = c1.size() - c2.size();

The javadoc does not conform to the code :) You do not return a value
if the size is unequal.

Have you considered using Test Driven Design to write such a library? I
usually do this because it works well for me focussing on a given
detail, while the tests catch if I mess something up.
