Java 11 came up with a cool feature to execute source code in single file without compiling it pre-hand

Lets assume file contains following beautiful world changing source code

For ages, we do the following

But from Java 11, its further simplified like below

So how it works ?

  • From Java 11, java command can compile as well as execute the Java source file
  • Remember, no .class file will be created while running java
  • java command executes the main method from the 1st class
  • public keyword in class Vicky proved insignificant in this case

Though these are small features, I feel its right step towards simplifying Java…

Thanks for reading..
