Find or Print Fibonacci Series using Java 8 Streams API
In the above example, It uses iterate method of Streams to generate an infinite stream of integer arrays, where each array contains the next two terms in the sequence. After that, The limit method is applied to limit the stream to the first number terms, and then map method is applied to extract the first term of each array, which actually represents the next number in the Fibonacci series. And, at last, forEach method is used to print each number to the console by applying sysout.
