JAVA libraries

Question

isn't AtomicBoolean function implemented in java libraries in soloLearn?

I was coding: https://code.sololearn.com/c5GlFghF9nFt/#java when I realised that I couldn't find java.util.concurrence.atomic any help?

Answer 1

Just import the AtomicBoolean class itself. Replace line 2 with:

import java.util.concurrent.atomic.AtomicBoolean;

Answer 2
