OOPs concepts in Java include inheritance, polymorphism, encapsulation, and abstraction.

• Inheritance allows a subclass to inherit properties and methods from a superclass.

• Polymorphism allows objects to take on multiple forms and behave differently based on their context.

• Encapsulation hides the implementation details of an object and only exposes necessary information.

• Abstraction allows for the creation of abstract class...read more

Interfaces define contracts for behavior, while inheritance allows for code reuse and polymorphism.

• Interfaces allow for loose coupling and abstraction, enabling multiple implementations of the same behavior.

• Inheritance allows for code reuse and extension of existing classes, reducing code duplication.

32 bit architecture can address up to 4GB of RAM, while 64 bit can address much more.

• 32 bit architecture has a maximum addressable memory of 4GB

• 64 bit architecture can address much more memory, up to 16 exabytes

• 64 bit architecture can perform more calculations per clock cycle

• 64 bit architecture is required for running certain software, such as Adobe Creative Suite

• 32 bit architecture is still commonly used in older syst
