OOPs (Object-Oriented Programming) is a programming paradigm that uses objects to design applications and programs.
OOPs focuses on creating reusable code and organizing it into objects.
It involves the concepts of inheritance, encapsulation, and polymorphism.
Inheritance allows a class to inherit properties and methods from another class.
Encapsulation is the process of hiding data and methods within a class.
Polymorphism ...
Inheritance allows for code reuse and promotes polymorphism.
Inheritance allows for creating a new class from an existing class.
The new class can inherit all the properties and methods of the existing class.
Inheritance promotes code reuse and reduces code duplication.
Inheritance also allows for polymorphism, where objects of different classes can be treated as if they are of the same class.
For example, a Car class can i...
String is immutable, StringBuilder and StringBuffer are mutable. StringBuffer is thread-safe.
String is immutable, meaning its value cannot be changed once it is created.
StringBuilder and StringBuffer are mutable, meaning their values can be changed.
StringBuilder is not thread-safe, while StringBuffer is thread-safe.
Use StringBuilder when you don't need thread-safety, and StringBuffer when you do.
Example: String str = "...
String is immutable to ensure thread safety and security. String pooling is a technique to reuse string literals.
Immutable strings prevent accidental modification and ensure thread safety.
String pooling reduces memory usage by reusing string literals.
String objects can be created using the new keyword, but it is not recommended.
StringBuffer and StringBuilder classes can be used for mutable strings.

OOOps stands for Out Of Order packets. It refers to packets that arrive at their destination out of sequence.
OOOps can occur in network communication when packets are sent out of order and arrive at the destination in a different order than they were sent.
This can lead to issues in data transmission and can cause delays in processing the information.
One way to handle OOOps is by using sequence numbers in packets to ens...
Exception handling is a mechanism to handle runtime errors and prevent program crashes.
It is a way to deal with unexpected errors or exceptional conditions in a program.
Exceptions can be caught and handled using try-catch blocks.
Common exceptions include NullPointerException, ArrayIndexOutOfBoundsException, and IOException.
