Inheritance in Java
๐ Inheritance allows a class to acquire properties and methods of another class.
๐ It promotes code reusability and hierarchical classification.
๐ The extends keyword is used to inherit from a class.
Example:
class Parent {
void show() {
System.out.println("This is the parent class");
}
}
class Child extends Parent {
void display() {
System.out.println("This is the child class");
}
}
public class Main {
public static void main(String[] args) {
Child obj = new Child();
obj.show(); // Inherited method
obj.display(); // Child class method
}
}

Polymorphism in Java
๐ Polymorphism allows a single interface to be used for different types of actions.
๐ It is of two types:
Method Overloading (Compile-time Polymorphism)
Method Overriding (Runtime Polymorphism)
Method Overloading (Same method name, different parameters)
class MathOperations {
int add(int a, int b) {
return a + b;
}
double add(double a, double b) {
return a + b;
}
}
Method Overriding (Same method in parent and child class)
class Animal {
void makeSound() {
System.out.println("Animal makes a sound");
}
}
class Dog extends Animal {
void makeSound() {
System.out.println("Dog barks");
}
}
