JShell is a new java shell tool released in java 9. It is the first official REPL (Read-Evaluate-Print-Loop) application. This tool helps in executing and evaluating simple java programs and logics such as statements, loops, expressions, and etc. Java REPL provides a simple programming environment in the command prompt. It can read the input, evaluate it and print the output.
In the below example we can able to create a class and object in JShell using command prompt.
Example
jshell> class Employee {
...> private String name;
...> Employee(String name) {
...> this.name=name;
...> }
...> String getName() {
...> return name;
...> }
...> void setName(String name) {
...> this.name=name;
...> }

jshell> Employee emp = new Employee("Adithya")
emp ==> Employee@4b952a2d
jshell> emp.getName()
$3 ==> "Adithya"
