OOPS concepts in C# include inheritance, encapsulation, polymorphism, and abstraction.

• Inheritance allows a class to inherit properties and behavior from another class.

• Encapsulation hides the internal state of an object and restricts access to it.

• Polymorphism allows objects of different classes to be treated as objects of a common superclass.

• Abstraction focuses on the essential characteristics of an object while ignoring irrelevant details.

String is immutable in Java, meaning its value cannot be changed once it is created.

• In Java, when you modify a string, a new string object is created instead of modifying the original one.
