Java 8 Stream distinct method example.


The Stream.distinct() method returns a stream consisting of the distinct elements of this stream. It uses Object.equals() method.

For ordered streams, the selection of distinct elements is stable (for duplicated elements, the element appearing first in the encounter order is preserved.) For unordered streams, no stability guarantees are made.

package com.java2novice.streams;

import java.util.stream.Stream;

public class StreamDistinctEx {

	public static void main(String a[]) {

		Stream.of("bus", "car", "bycle", "bus", "car", "car", "bike")
				.distinct()
				.forEach(System.out::println);
	}
}

Output:
bus
car
bycle
bike

What is adapter class?
An adapter class provides the default implementation of all methods in an event listener interface. Adapter classes are very useful when you want to process only few of the events that are handled by a particular event listener interface. You can define a new class by extending one of the adapter classes and implement only those events relevant to you.
