What happens if I don't use the "<>" when calling the constructor. Example: Stack myStack = new Stack();

Do I need to set the Class inside of the "<>" when calling the constructor in the "new Stack<>();"?, and why. Example Stack <Integer> myStack = new Stack();.

Thank you!3

Dev.java: The Destination for Java Developers
Introducing Generics - Dev.java

Generics enable types (classes and interfaces) to be parameters when defining classes, interfaces and methods. Much like the more familiar formal parameters used in method declarations, type parameters provide a way for you to re-use the same code with different inputs.

The warning shows that raw types bypass generic type checks, deferring the catch of unsafe code to runtime. Therefore, you should avoid using raw types.
