Question

Help answering some basic computer science questions.. no coding required just informational questions:

1. Compare ArrayLists and Arrays.  
2. What is the Type Inference and what are its advantages?
3. List the advantages of parameterized classes.
4. What are Type Parameter Bounds and what are their advantages?
5. What are the primary purposes of the Collection Interface and what do some of its methods do?

Answer 1

ArrayList size grows dynamically an Arrays are fixed in the size and ArrayList has methods to work where Arrays does not have any methods

Interface is collection of abstract methods . we can specify all required implementaitions in interfaces and we can achieve mulitple inheritance with help of interfaces

Parameterized classes will help us work with any kind of data

Type Parameter Bounds add limitations to your class like which all types your class should accept it as parameters

Collection interface will provide functions for usage so that all classes which are implementing these interface should provide definitions for all these methods
