Four Pillars of OOP Encapsulation : This principle restricts direct access to some of an object's components and can prevent the accidental modification of data. It is achieved by using access modifiers (private, protected, public). Example : java Insert Code Edit Copy code 1 class BankAccount { 2 private double balance ; 3 4 public void deposit ( double amount ) { 5 if ( amount > 0 ) { 6 balance += amount ; 7 } 8 } 9 10 public double getBalance ( ) { 11 return balance ; 12 } 13 } Abstraction : This involves hiding complex implementation details and showing only the essential features of the object. It simplifies interaction with objects. Example : java Insert Code Edit Copy code 1 abstract class Animal { 2 abstract void sound ( ) ; 3 } 4 5 class Dog extends Animal { 6 void sound ( ) { 7 System . out . println ( "Woof" ) ; 8 } 9 } Inheritance : Thi
