WSL2: Find and Delete Zone.Identifier files

Final java has variable declaration without worrying of type declaration. The keyword var is introduced in java10.

var age=10;
var name="jai";
var emp= new Employee();

wow what a great feature included in java

Note: we can use var for local variables only, we can not use for instance variables
Note: we must assign the value for var variable at the time of creation.
