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.

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 = "hello"; StringBuilder sb = new StringBuilder(str);

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 inherit from a Vehicle class, which can have properties and...read more

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 allows objects to take on multiple forms or behaviors.
