Java certification is not mandatory for a Java Developer role.
Certification is not a measure of practical skills and experience.
Experience and skills are more important than certification.
Certification can be helpful in some cases, but not mandatory.
Certification can be expensive and time-consuming.
Employers may value certification differently.
Examples of Java certifications: Oracle Certified Professional Java SE 11 De
The four pillars of OOPS are Abstraction, Encapsulation, Inheritance, and Polymorphism.
Abstraction: Hiding implementation details and showing only necessary information.
Encapsulation: Binding data and methods together to protect data from outside interference.
Inheritance: Creating new classes from existing ones, inheriting properties and methods.
Polymorphism: Ability of objects to take on multiple forms or behaviors.
Polymorphism is when an object can take on multiple forms and behave differently based on the context.
A car can be a vehicle, but it can also be a sports car or a family car, each with different behaviors.
A shape can be a square, rectangle, or triangle, each with different methods for calculating area and perimeter.
A media player can play different types of media, such as audio or video, each with different playback co
Abstract class can have implementation while interface cannot. A class can implement multiple interfaces but can only extend one abstract class.
Abstract class can have constructors while interface cannot.
Abstract class can have instance variables while interface cannot.
Abstract class can have non-abstract methods while interface can only have abstract methods.
A class can implement multiple interfaces but can only exten...
Yes, Java supports multi level inheritance.
Multi level inheritance is the process of inheriting a class from another derived class.
It helps in creating a hierarchy of classes with each level inheriting properties from the previous level.
For example, class C can inherit from class B, which in turn inherits from class A.
Java does not support multiple inheritance, where a class can inherit from multiple classes at the sam
Composition is a way to combine objects to create complex structures, while inheritance is a way to create new classes based on existing ones.
Composition is a 'has-a' relationship, where an object contains other objects as its parts.
Inheritance is an 'is-a' relationship, where a subclass inherits properties and behaviors from its superclass.
Composition allows for greater flexibility and modularity in design, as objects...
Exception handling is the process of handling errors and exceptions that occur during program execution.
Exceptions are objects that represent errors or exceptional situations that occur during program execution.
Exception handling involves catching and handling these exceptions to prevent program crashes.
Java provides try-catch-finally blocks for handling exceptions.
Examples of exceptions include NullPointerException, A...
throw is used to explicitly throw an exception while throws is used to declare an exception that a method may throw.
throw is used within a method to throw an exception when a certain condition is met
throws is used in the method signature to declare the exceptions that the method may throw
throw is followed by an instance of an exception class while throws is followed by the name of the exception class
throw is used to ha...
Yes, we can have multiple try blocks in Java.
Multiple try blocks can be used to handle different exceptions separately.
Each try block must have at least one catch or finally block.
Nested try blocks can also be used.
Example: try { //code } catch (Exception e) { //code } try { //code } catch (IOException e) { //code }
Example of nested try blocks: try { try { //code } catch (Exception e) { //code } } catch (Exception e) {
Memory is allocated when an instance of a class is created.
Memory allocation happens when an object is created using the 'new' keyword.
Static variables are allocated memory when the class is loaded.
Memory is released when the object is no longer referenced or when the program terminates.
A stack is a data structure that follows the Last In First Out (LIFO) principle.
Elements are added and removed from the top of the stack.
Push() adds an element to the top of the stack.
Pop() removes the top element from the stack.
Peek() returns the top element without removing it.
Used in programming for function calls, expression evaluation, and memory management.
A queue is a data structure that follows the FIFO (First In First Out) principle.
Elements are added to the back of the queue and removed from the front.
Common operations include enqueue (add to back) and dequeue (remove from front).
Examples include a line of people waiting for a movie or a printer queue.
Java provides the Queue interface and its implementations like LinkedList and PriorityQueue.
Errors are unrecoverable, while exceptions are recoverable.
Errors are caused by the environment in which the application is running, while exceptions are caused by the application itself.
Errors cannot be handled by the application, while exceptions can be handled using try-catch blocks.
Examples of errors include OutOfMemoryError and StackOverflowError, while examples of exceptions include NullPointerException and Array
We can use composition, aggregation, or association to connect two classes.
Composition is a strong form of aggregation where the lifetime of the contained object is controlled by the container object.
Aggregation is a weaker form of composition where the contained object has an independent lifecycle.
Association is a relationship between two classes where one class uses the functionality of another class.
Examples of asso...
Access modifiers in Java are used to set the accessibility of classes, methods, and variables.
There are four types of access modifiers in Java: public, private, protected, and default.
Public: accessible from anywhere in the program.
Private: accessible only within the same class.
Protected: accessible within the same class, same package, and subclasses.
Default: accessible within the same package only.
protected is a Java access modifier that allows access within the same package and subclasses.
Protected members can be accessed within the same package and subclasses.
It is used to provide encapsulation and prevent direct access from outside the class.
Protected members can be accessed using the dot operator.
Example: protected int num; can be accessed in a subclass using obj.num;
No, subclass cannot access private methods of parent class.
Private methods are only accessible within the same class where they are defined.
Subclasses can access protected and public methods of parent class.
Private methods can be accessed indirectly through public or protected methods of parent class.
No, subclass cannot inherit properties of parent class if parent class is not loaded.
In order for a subclass to inherit properties of a parent class, the parent class must be loaded.
If the parent class is not loaded, the subclass will not have access to its properties.
This is because inheritance is a compile-time concept and requires the parent class to be present during compilation.
Attempting to access properties of a...
Yes, a class can be private in Java.
A private class can only be accessed within the same outer class.
It cannot be accessed from outside the class or even from subclasses.
Private classes are often used for implementation details that should not be exposed to other classes.
Example: private class Node in a LinkedList implementation.
Collections are objects that group multiple elements into a single unit.
Collections are used to store, retrieve, manipulate and communicate aggregate data.
Java provides a set of interfaces and classes that implement various types of collections.
Examples of collections include List, Set, Map, Queue, etc.
Collections can be used to improve code readability, reusability, and performance.
Collections are used to store and manipulate groups of objects in Java. There are three main types of collections.
The three main types of collections are List, Set, and Map.
List is an ordered collection that allows duplicates. Example: ArrayList.
Set is an unordered collection that does not allow duplicates. Example: HashSet.
Map is a collection that maps keys to values and does not allow duplicate keys. Example: HashMap
Arrays are fixed in size and stored in stack memory, while heap is dynamic and stored in heap memory.
Arrays are declared with a fixed size, while heap can grow or shrink dynamically.
Arrays are stored in stack memory, while heap is stored in heap memory.
Arrays can only store elements of the same data type, while heap can store objects of different types.
Examples of arrays include int[], char[], and String[], while examp...
No, Set does not allow duplicates.
Set is a collection that does not allow duplicates.
If you try to add a duplicate element to a Set, it will not be added.
You can use a List if you need to allow duplicates.
Yes, duplicates can be added to an array.
Arrays in Java can contain duplicate elements.
Duplicate elements can be added to an array using the add() method of ArrayList class.
For example, int[] arr = {1, 2, 3, 3, 4}; or ArrayList
