How to implement the Fibonacci series in JShell in Java 9?

JavaObject Oriented ProgrammingProgramming

JShell is a java shell tool introduced in Java 9 that allows us to execute Java code and prints the result immediately. It is a REPL (Read-Evaluate-Print-Loop) tool that runs from the command-line prompt. 

A number is said to be the Fibonacci series if each subsequent number is the sum of the previous two numbers.

In the below example, we can able to implement the Fibonacci Series in the JShell tool.

| For an introduction type: /help intro

jshell> int x=0, y=1, z=0, count=5;
x ==> 0
y ==> 1
z ==> 0
count ==> 5

jshell> {
...>       System.out.println(x+"\n"+y);
...>       for(int i=0; i<count; i++) {
...>          x=y; y=z;
...>          z = x+y;
...>          System.out.println(z);
