What is Encapsulation in java ? 📍 Encapsulation is one of the fundamental principle of object oriented programming . 📍 Encapsulation allows to protect the data within a class from outside entities. 📍 Encapsulation helps to achieve hiding the internal information from outside entities. 📍 Data and methods (To access the data) are bundled together within a single unit .(class) 📍 In Java, encapsulation is typically achieved by: Declaring the class members as private. Providing public getter and setter methods to access and modify the private attributes. Note : Let's say we have 1 private variables in a class Example - 1: getter & setter for primitive type private members. private String empnm; // get method to access the data public String GetName() { return empnm; } // set the data public void setName(String enm) { this.empnm = enm; } // call the method & pass the data as param If we can notice the getter & setter for empnm , below points we can note: 1. getter method will return the variable which is private and it is non parameterized . 2. setter method is a parameterized method which we shall use to set the value for the private member while calling , so only it is parameterized method. Example -2 :getter & Setter for the private array : public int[] getarr() { return arr; } // Setter method to modify the private array public void setarr(int[] brr) { // You can add validation or other logic if needed this.arr = brr; } Best Programming Resources: https://topmate.io/coding/886839 All the best 👍👍
