Fixed code smells after running sonarqube on the project

-Generic types shouldn't be used raw (without type parameters) in variable declarations or return values. Doing so bypasses generic type checking, and defers the catch of unsafe code to runtime. https://rules.sonarsource.com/java/RSPEC-3740
- The dangling else problem appears when nested if/else statements are written without curly braces. In this case, else is associated with the nearest if but that is not always obvious and sometimes the indentation can also be misleading.
https://rules.sonarsource.com/java/tag/confusing/RSPEC-5261

String literals should not be duplicated
https://rules.sonarsource.com/java/RSPEC-1192

- Local variable names in java must be with the  default regular expression ^[a-z][a-zA-Z0-9]*$
https://rules.sonarsource.com/java/tag/convention/RSPEC-117
- The diamond operator ("<>") should be used when the type of the maps are already defined
https://rules.sonarsource.com/java/RSPEC-2293
- Package names being camel cased is a code smell

Fix maven link and correct Stack implementation

The previous implementation would show unexpected behaviour when using the values returned by pop() and peek().
Generic type was needed but not used in implementation thus leading to redundancy.
push() had unnecessary return type.

Since January 15, 2020 Maven Central no longer supports insecure communication over plain HTTP and requires that all requests to the repository are encrypted over HTTPS.
