February 28, 2018 | 0 Minute Read

In my personal opinion, one of most beautiful components of Java9 is Java shell. Let us go back to our fist class of learning Java. Back then, I didn’t know why I had to create void method for printing “Hello”. But Java 9 provides Java shell for efficiency way of learning java curves. we don’t need to create methods in java shell.

Advantages

• no more “public static void main(String[] args)” method.
• provides a Read Eval Print Loop(REPL) shell for Java.
• provideds immediate feeback for learning Java and its APIs.

How to use

1. open your command prompt
2. type “jshell -v”

Past java versions

public class Main {
  public sttic void main (String[] args) {
    System.out.println("Hello Jin");
  }
}

In JShell
