Explore Java Stream.of() Method

Java Streams provide a powerful and expressive way to process data collections in a functional style. The Stream.of() method is a fundamental part of the Java Stream API, allowing you to create streams from individual elements or arrays.

Introduction to Stream.of()

The Stream.of() method is a static factory method defined in the java.util.stream.Stream class. It allows you to create a stream from a sequence of elements or from an array of elements. This method is especially useful when you need to work with a small number of elements or when you want to convert a fixed set of data into a stream.

Creating a Stream from Elements

You can use Stream.of() to create a stream from individual elements. Here’s a simple example:

Stream<Integer> numberStream = Stream.of(1, 2, 3, 4, 5); // stream of integers
Stream<Character> charStream = Stream.of('a', 'b', 'c', 'd', 'e'); // stream of characters

Creating a Stream from an Array

Stream.of() can also be used to create a stream from an array of elements. Here’s how you can do it:

String[] array = {"apple", "banana", "cherry", "date"};
Stream<String> streamFromArray = Stream.of(array);

Conclusion

The Stream.of() method in Java is a versatile tool for creating streams from individual elements or arrays. It simplifies the process of working with small data sets, and it’s particularly handy when you need to convert existing data into a stream for further processing.
