- Q1. What is Object oriented programming
- Ans.
Object oriented programming is a programming paradigm based on the concept of objects, which can contain data and code.
OOP focuses on creating objects that interact with each other to solve problems
Encapsulation, inheritance, and polymorphism are key principles of OOP
Examples of OOP languages include Java, C++, and Python
- Q2. What is multi threading
- Ans.
Multi threading is a programming concept where multiple threads within a process execute independently to improve performance.
Allows for concurrent execution of tasks within a single process
Improves performance by utilizing multiple CPU cores

- Q3. Why is java not 100% oop
- Ans.
Java is not 100% OOP because it supports primitive data types and static methods.
Java has primitive data types like int, double, etc. which are not objects.
Java allows static methods which do not require an instance of a class to be called.
Java also has the concept of wrapper classes to convert primitive data types to objects.
- Q4. What are collections in java
- Ans.
Collections in Java are classes and interfaces that provide a way to store and manipulate groups of objects.
Collections provide dynamic data structures like List, Set, and Map.
They offer methods to add, remove, and manipulate elements in the collection.
Examples include ArrayList, LinkedList, HashSet, and HashMap.
- Q5. Internal working of hash map
- Ans.
A hash map is a data structure that stores key-value pairs and uses a hash function to map keys to their corresponding values.
Hash map uses a hash function to determine the index of the key-value pair in the underlying array.
Collision resolution techniques like chaining or open addressing are used to handle situations where multiple keys hash to the same index.
Hash maps typically have O(1) average time complexity for i...

Examples of platform independent Java applications include web applications, mobile apps, and enterprise software.
- Q3. Difference between abtract and interface key words?
- Ans.
Abstract classes can have both abstract and non-abstract methods, while interfaces can only have abstract methods.
Abstract classes can have constructors, fields, and non-abstract methods, while interfaces cannot.
A class can only extend one abstract class, but it can implement multiple interfaces.
Abstract classes are used to define common characteristics of subclasses, while interfaces are used to define contracts for c...

- Q2. Built in functions of string
- Ans.
Built-in functions of string are pre-defined functions in programming languages that can be used to manipulate strings.
Some common built-in functions of string include: length(), substring(), toUpperCase(), toLowerCase(), trim(), indexOf(), charAt().
Example: str.length() returns the length of the string 'str'.
Example: str.substring(2, 5) returns the substring of 'str' starting from index 2 to 5.
Example: str.toUpperCase...
