Wrapper classes are those classes such as Integer, Float, etc that wrap your basic data types such as int, float, etc and provide additional functionality and operations on these data types, other than just being able to store/retrieve a variable of the basic data type.

- System refers to the class System (java.lang.System).
- out is the static PrintStream (java.io.PrintStream) variable of the System class. It is nothing but the standard output stream.
- println is a method of the PrintStream class that prints the data to the output stream.

index cannot be static. Clearly, this represents a stack and obviously you cannot have one common index value (top pointer) across all stacks!!!!!
