Generics also provide compile-time type safety which allows programmers to catch invalid types at compile time. Generic means parameterized types.

Using generics, the idea is to allow any data type to be it Integer, String, or any user-defined Datatype and it is possible to create classes that work with different data types.

A Generic class simply means that the items or functions in that class can be generalized with the parameter(example T)to specify that we can add any type as a parameter in place of T like Integer, Character, String, Double or any other user-defined type.

Example: Single type parameter

class Solution<T> { T data; public static T getData(){ return data; } }

Example: Multiple type parameters

public class Pair<K, V> { private K ke
