REPL, or read-eval-print-loop, is a shell interface that reads each line of input, evaluates that line, and then prints the result, hence you get instant feedback. And when you use a REPL, you are writing code interactively and executing it without delay.

Thanks pranshu for your help.

Hi Rashmi,

Java REPL is an interactive Java shell. REPL stands for Read-Eval-Print-Loop, which means it will read each line of input, evaluate that line, then print out the result

REPL is useful to get instant feedback/evaluation for an expression you are trying to implement in your own Java programs. It lets you experiment and see exactly how Java will evaluate your inputs without having to worry about incorporating it into your code only to find out what you are trying to do doesn't work.

I hope that helps!
