findFirst() and findAny() are methods in the Stream interface in Java that are used to find the first or any element in a stream that matches a given condition. Java8…
Java 8 introduced the Stream API, which allows you to perform functional-style operations on collections of data. Here are some examples of using the Stream API: 1. Filtering a list…
Map: If you want to transform into single value then use Map The map method is used to apply a function to each element in a stream, and return a…
peek() method in a stream pipeline is used to perform a certain action on each element of the stream, without modifying the elements themselves. It allows for debugging or other…
In this post we will see Collectors examples which used to collect elements. Collectors Examples The collect method is used to perform a reduction operation on a stream Used to…
Supplier is a functional interface that defines a method called get() that returns an instance of a certain type without taking any arguments. The Supplier interface is commonly used to…
the reduce method is used to perform a reduction operation on a stream, which combines all the elements in the stream into a single value. Here’s an example of using…
A parallel stream is a stream that is capable of executing operations in parallel, meaning that the operations are divided into smaller tasks and executed concurrently on multiple threads. A…
In Java 8, streams use a technique called “lazy evaluation” to process data. Lazy evaluation means that a stream operation is not executed until it is absolutely necessary. This can…
