Collections
utility algorithmstatic
methods likesort()
,binarySearch()
,max()
,min()
, andreverse()
. - Collection stream pipelines and aggregate operations with lambdas.
Knowing these topics will help you create enterprise-level programs and handle data more efficiently by not needing to “reinvent the wheel” and fully utilize the power of the collections framework.
Instructions
Use the workspace to explore collections and using lambdas to help construct pipelines.
