The Collectors.maxBy() method is used to find the maximum element from a stream based on a certain comparator. It returns an Optional which contains the maximum element according to the provided comparator, or an empty Optional if there are no elements in the stream. Here’s a simple example where we have a list of integers, […]
The Collectors.minBy() method in Java 8 is used to find the minimum element from a stream of elements based on a certain comparator. It returns an Optional describing the minimum element of the stream, or an empty Optional if the stream is empty. Here’s an example of how to use Collectors.minBy(). Assume we have a […]
The Collectors.counting() method is a terminal operation that returns the count of elements in the particular stream where it is used. This is part of the java.util.stream.Collectors in Java 8. Here is a simple example of how to use Collectors.counting(). Suppose we have a list of strings, and we want to count the number of […]
The Collectors.toCollection() method is a static method in the java.util.stream.Collectors class of Java 8. This method is used with streams when you want to convert a list to another collection type.

Base64 encoding scheme is designed to encode binary data, especially when that data needs to be stored and transferred over media that designed to deal with text. Base64 encoding helps to ensure that the data remains intact without modification during transport. Base64 is a group of similar binary-to-text encoding schemes that represent binary data in […]
