The interviewer was really cool. He realized that I mostly work on java applications so he chose to ask me stuff related to that. He didn't want me to know the answer well but just wanted me to approach to it, maybe think more. He went through my resume back and forth and asked mostly about all my projects and their logic and how could I take them to the next level.
Tips: Be confident. Its okay not to know any answer, just try giving it a shot in the approach.
Abstract class can have both abstract and non-abstract methods, while interface can only have abstract methods.
Abstract class can have constructors, member variables, and methods with implementation.
Interface can only have abstract methods and constants.
A class can implement multiple interfaces but can only extend one abstract class.
Example: Abstract class - Animal with abstract method 'eat', Interface - Flyable with m
final is a keyword used to declare constants, finally is a block used in exception handling, and finalize is a method used for cleanup.
final is a keyword used to declare constants in Java, meaning the value cannot be changed once assigned. Example: final int x = 10;
finally is a block used in exception handling to ensure a piece of code is always executed, whether an exception is thrown or not. Example: try { // code } ...
Private restricts access to the class itself, while final prevents inheritance and method overriding.
Private access modifier restricts access to the class itself, while final access modifier prevents inheritance and method overriding.
Private members are only accessible within the same class, while final classes cannot be extended and final methods cannot be overridden.
Example: private int num; - num can only be accesse...
Establishing a JDBC connection involves loading the driver, creating a connection, creating a statement, executing queries, and handling exceptions.
Load the JDBC driver using Class.forName() method
Create a connection using DriverManager.getConnection() method
Create a statement using connection.createStatement() method
Execute queries using statement.executeQuery() method
Handle exceptions using try-catch blocks
JSON is a lightweight data interchange format used to store and transmit data between a server and a web application.
JSON stands for JavaScript Object Notation.
It is easy for humans to read and write, and easy for machines to parse and generate.
JSON is language-independent and can be used with any programming language.
Example: {"name": "John", "age": 30}
Example: [{"name": "Alice", "age": 25}, {"name": "Bob", "age": 35}
Garbage collection in Java is the process of automatically managing memory by deallocating objects that are no longer needed.
Garbage collection helps in preventing memory leaks by reclaiming memory used by objects that are no longer referenced.
Java uses a garbage collector to automatically manage memory, unlike languages like C++ where memory management is manual.
Garbage collection in Java can be triggered by calling S...

I wouldn't say it went great but it was fine. I did not think I would clear it as for most of the questions the interviewer seemed disappointed and wanted more out of me.

Inheritance is a mechanism in object-oriented programming where a new class is created by inheriting properties of an existing class.
Inheritance allows code reuse and promotes code organization.
The existing class is called the parent or superclass, and the new class is called the child or subclass.
The child class inherits all the properties and methods of the parent class and can also add its own unique properties and ...
finally is a keyword used in try-catch block, finalize is a method in Object class, and final is a keyword used for declaring constants.
finally is used to execute a block of code after try-catch block
finalize is called by garbage collector before destroying an object
final is used to declare a constant variable or to make a class uninheritable
Private keyword restricts access to member functions within the class while final keyword prevents overriding of functions.
Private keyword is used to hide the implementation details of a class from the user.
Final keyword is used to prevent the user from overriding a function in a subclass.
Using private and final keywords together can ensure that the implementation details of a class are not modified by the user.
An interface defines a set of methods that a class must implement.
An interface is declared using the 'interface' keyword.
All methods in an interface are public and abstract by default.
A class can implement multiple interfaces.
Interfaces can also extend other interfaces.
Example: public interface MyInterface { void myMethod(); }
Abstract class is a class with some implementation while Interface is a contract with no implementation.
Abstract class can have constructors while Interface cannot
Abstract class can have non-abstract methods while Interface cannot
A class can implement multiple interfaces but can only inherit from one abstract class
Abstract class is used when there is a need for common functionality among related classes while Interface...
Inheritance types in Java
Java supports single and multiple inheritance through classes and interfaces respectively
Single inheritance is when a class extends only one parent class
Multiple inheritance is when a class implements multiple interfaces
Java also supports hierarchical inheritance where multiple classes extend a single parent class
Java does not support multiple inheritance through classes to avoid the diamond pr
Order of catch blocks in a try block in Java
Specific catch blocks should come before general catch blocks
If general catch block comes before specific catch block, it will result in a compile-time error
If multiple catch blocks are present, only the first matching catch block will be executed
Garbage collection is an automatic memory management process that frees up memory occupied by objects that are no longer in use.
Garbage collection is used in programming languages like Java, C#, and Python.
It helps prevent memory leaks and reduces the risk of crashes due to memory exhaustion.
Garbage collection works by identifying objects that are no longer in use and freeing up the memory they occupy.

JSON stands for JavaScript Object Notation, a lightweight data interchange format.
JSON is used to transmit data between a server and a web application, as an alternative to XML.
It is easy to read and write for humans and easy to parse and generate for machines.
JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of the C family of languages.
Example: {"name"

A trigger is a special type of stored procedure that automatically executes when certain events occur in a database.
Triggers are used to enforce business rules, maintain data integrity, and automate repetitive tasks.
They can be triggered by INSERT, UPDATE, or DELETE operations on a table.
Examples of triggers include auditing changes to a table, updating related tables when a record is modified, or enforcing referential
Clustered indexes physically order the data in the table, while non-clustered indexes do not.
Clustered indexes determine the physical order of data in the table, while non-clustered indexes do not.
A table can have only one clustered index, but multiple non-clustered indexes.
Clustered indexes are faster for retrieval of data, especially range queries, compared to non-clustered indexes.
Non-clustered indexes are stored se...
