Java Stream distinct Get Unique Values from Stream HowToDoInJava
The distinct returns the distinct elements from the given stream For checking the equality of the stream elements the equals method is used The distinct guarantees the ordering for the streams backed by an ordered collection The element appearing first in the encounter order is preserved for ordered streams
DistinctBy in Java Stream API Baeldung, The Stream API provides the distinct method that returns different elements of a list based on the equals method of the Object class However it becomes less flexible if we want to filter by a specific attribute One of the alternatives we have is to write a filter that maintains the state 2 1 Using a Stateful Filter
