this needs to be in java language plz!! lab7

Part 1: Java Generics Using the solution for Lab 6 StringArray posted on Brightspace, rename the StringArray class to GenericArray. Modify the code throughout using Java generics to allow your GenericArray class to store any generic type, rather than String objects
