Why generic collections are preferred over non-generic collections?
Code reusability: Generics help in reusing the code already written, thereby making it usable for other types (for a method, or class, or an interface). If a data structure is generic, say a list, it would only take specific type of objects and return the same specific type of object as output.
Which is not a generic collection?
Non-generic collections hold elements of different datatypes. The following are the non-generic collections: ArrayList, BitArray. ArrayList − It represents ordered collection of an object that can be indexed individually. ArrayList is an alternative to an array.

What is generic and non-generic class?
A Generic collection is a class that provides type safety without having to derive from a base collection type and implement type-specific members. A Non-generic collection is a specialized class for data storage and retrieval that provides support for stacks, queues, lists and hashtables.

Is it a good idea to use generics in collections?
By using generics, programmers can implement generic algorithms that work on collections of different types, can be customized, and are type safe and easier to read.

What is a generic collection?
A generic collection is strongly typed (you can store one type of objects into it) so that we can eliminate runtime type mismatches, it improves the performance by avoiding boxing and unboxing.

Why do we need generics in collection?
Code that uses generics has many benefits over non-generic code: Stronger type checks at compile time. A Java compiler applies strong type checking to generic code and issues errors if the code violates type safety. Fixing compile-time errors is easier than fixing runtime errors, which can be difficult to find.
Why are generics used in collections?
The generic collections disable the type-casting and there is no use of type-casting when it is used in generics. The generic collections are type-safe and checked at compile-time. These generic collections allow the datatypes to pass as parameters to classes.

What are generics in collections?

What is the difference between generic and non-generic collections in Java?
The System.Collections namespace contains the non-generic collection types and System.Collections.Generic namespace includes generic collection types. In most cases, it is recommended to use the generic collections because they perform faster than non-generic collections and also minimize exceptions by giving compile-time errors.
