Utility to create the full class name given the package and class name.
Some examples
packageName=test className=Test, returns result=test.Test
packageName=test className=test1.Test, returns result=test1.Test
packageName=<null> className=Test, returns result=Test
packageName=<null> className=test1.Test, returns result=test1.Test
Parameters:
pkg_name - package name.
Parameters:
cls_name - class name. |
