oop concepts
Encapsulation:
Encapsulation is the bundling of data (attributes) and methods that operate on the data into a single unit known as a class. It helps in hiding the internal implementation details of the class
public class BankAccount {
private double balance;
public void deposit(double amount) {
balance += amount;
}
public double getBalance() {
return balance;
}
}
Inheritance:
Inheritance allows a class to inherit properties and behaviors from another class. The class that is being inherited from is called the superclass or parent class, and the class that inherits is called the subclass or child class.
java
public class Animal {
void eat() {
System.out.println("This animal eats.");
}
}
public class Dog extends Animal {
void bark() {
System.out.println("The dog barks.");
}
}
Polymorphism:
Polymorphism allows objects to be treated as instances of their parent class rather than their actual class. This can be achieved through method overriding and interfaces.
java
public interface Shape {
void draw();
}
public class Circle implements Shape {
@Override
public void draw() {
System.out.println("Drawing a circle.");
}
}
public class Square implements Shape {
@Override
public void draw() {
System.out.println("Drawing a square.");
}
}
Abstraction:
Abstraction involves simplifying complex systems by modeling classes based on the essential properties and behaviors they share. Abstract classes and interfaces in Java are used to achieve abstraction.
java
abstract class Shape {
abstract void draw();
}
class Circle extends Shape {
@Override
void draw() {
System.out.println("Drawing a circle.");
}
}
