Similarities between local variables and parameter variables:

Both local and parameter variables belong to methods and both of them come present on the execution when the method is called.

As the method is destroyed, both local and parameter variables destroyed.

Difference between local variables and parameter variables:

Local variables Parameter variables
Local variables are initialized explicitly...
