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.
There are differe...

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"
HashMap is a data structure that stores key-value pairs and uses hashing to efficiently retrieve values based on keys.
HashMap internally uses an array of linked lists to store key-value pairs.
When a key-value pair is added, the key is hashed to determine the index in the array where it will be stored.
If multiple keys hash to the same index, a linked list is used to handle collisions.
To retrieve a value, the key is hash...
Find anagrams from a string array
Iterate through each string in the array
Sort the characters of each string to create a key for comparison
Use a hashmap to group anagrams together
Return the grouped anagrams as arrays
A top view of a binary tree shows the nodes visible when looking at the tree from the top.
The top view of a binary tree is the set of nodes visible when looking at the tree from the top.
Nodes at the same horizontal distance from the root are considered at the same level.
Use a map to store the horizontal distance of each node and only keep the first node encountered at each horizontal distance.
Height of a binary tree is the maximum number of edges on the longest path from the root node to a leaf node.
Height of an empty tree is -1
Height of a tree with only one node is 0
Height of a binary tree can be calculated recursively by finding the height of left and right subtrees and adding 1 to the maximum of the two heights
Manual testing is important for exploratory testing, usability testing, and ad-hoc testing.
Manual testing allows for exploratory testing where testers can explore the application and identify unexpected issues.
Usability testing, which involves real users interacting with the software, is best done manually to capture user experience.
Ad-hoc testing, where testers randomly test the application without predefined test cas...
