Now, we can easily filter out the information required, sort them and perform almost all the stream operations provided by Java.

Jshell : Java REPL

Reading Time: 3 minutes A good programmer is always lazy when it comes to writing the code. They always try to complete their functionality in minimum lines of code. The same thing is expected by them when it comes to debugging or learning new features. In order to fulfill this requirement, almost every programming language has a REPL, a tool which has proved to be of great importance, especially for Continue Reading
