How to Kill a Java Thread Or How to stop a thread without using stop() method

let us see what are the other possible ways to stop the thread from its execution. This is a tricky topic for intermediate developers. Please read twice and practice the programs.

Java 8: Counting Matches on a Stream Filter - Stream.count(), Collectors.counting()

1. Overview

In this java 8 tutorial, We'll learn how to find the count of a Stream using Stream.count() and Collectors.counting() methods and also how to find the count that matches a specified condition or a Predicate. To use Predicate, we must use the filter() method from Stream API.
Let us start writing a few examples of finding count.
