Object-oriented programming concepts in Java
OOPs stands for Object-Oriented Programming
Key concepts include classes, objects, inheritance, polymorphism, encapsulation
Java supports OOPs principles like abstraction, encapsulation, inheritance, and polymorphism
Object-oriented programming concepts in Java
Encapsulation: bundling data and methods that operate on the data into a single unit
Inheritance: allows a class to inherit properties and behavior from another class
Polymorphism: ability of an object to take on many forms
Abstraction: hiding the implementation details and showing only the necessary features of an object

A for loop is a control flow statement for iterating a specific number of times.
Used to iterate over a range of values or elements in an array
Consists of initialization, condition, and increment/decrement expressions
Example: for(int i=0; i<5; i++) { System.out.println(i); }
Collections in Java are frameworks that provide an architecture to store and manipulate a group of objects.
Collections provide interfaces (List, Set, Map) and classes (ArrayList, LinkedList, HashSet, HashMap) to store and manipulate groups of objects.
Collections framework includes algorithms to manipulate data structures like sorting, searching, etc.
Collections are more flexible and efficient than arrays in Java.

Exception handling in Java is a mechanism to handle runtime errors and prevent program crashes.
Use try-catch blocks to handle exceptions
Use finally block to execute code regardless of exception
Use throw keyword to manually throw exceptions
Use throws keyword in method signature to declare exceptions that can be thrown
For loop syntax is used for iterating over a collection of elements in Java.
Syntax: for(initialization; condition; iteration) { // code block }
Initialization: executed before the loop starts
Condition: evaluated before each iteration, loop continues if true
Iteration: executed after each iteration
Example: for(int i=0; i<10; i++) { System.out.println(i); }
Syntax for declaring an array in Java
Declare the array type followed by square brackets and the array name
Initialize the array using curly braces with values separated by commas
Example: String[] names = {"Alice", "Bob", "Charlie"}

For loop is used to iterate over a collection of elements in Java.
Syntax: for(initialization; condition; update) { // code block }
Example: for(int i=0; i<10; i++) { System.out.println(i); }
A string in Java is a sequence of characters used to represent text.
Strings are objects in Java, created using the 'String' class.
Strings are immutable, meaning their values cannot be changed once they are created.
Strings can be concatenated using the '+' operator.
Example: String str = "Hello, World!";

OOPs stands for Object-Oriented Programming. It is a programming paradigm that uses objects to represent and manipulate data.
OOPs is based on the concept of classes and objects.
It focuses on encapsulation, inheritance, and polymorphism.
Encapsulation ensures data hiding and abstraction.
Inheritance allows the creation of new classes from existing ones.
Polymorphism enables objects to take on multiple forms.
Example: In Jav...
Multithreading is the concurrent execution of two or more threads to achieve maximum utilization of CPU.
Multithreading allows multiple threads to run concurrently within a single program.
It improves performance by utilizing idle CPU time and executing multiple tasks simultaneously.
Threads can communicate and share resources, but synchronization is required to avoid conflicts.
Examples include running background tasks wh...
Exception handling is a mechanism in Java to handle runtime errors and prevent program crashes.
Exception handling allows programmers to catch and handle errors that occur during program execution.
It involves using try-catch blocks to catch exceptions and provide alternative code to handle the error.
The catch block specifies the type of exception to catch and the code to be executed when that exception occurs.
