Encapsulation Explanation With Example In JAVA: Now we will explain the concept of Encapsulation with example. Example 1:In the below example, we will set two fields as private name and email in class UserDetails. So these fields can only be access within this class and no outside class can...
This way data can only be accessed by public methods thus making the private fields and their implementation hidden for outside classes. That’s why encapsulation is known asdata hiding.Lets see an example to understand this concept better. Key Concepts of Encapsulation in Java: Private Variables...
In Java, encapsulation helps us to keep related fields and methods together, which makes our code cleaner and easy to read. It helps to control the values of our data fields. For example, class Person { private int age; public void setAge(int age) { if (age >= 0) { this.age =...
We’ve created an anonymous function to hide the variables, and then defined the object as an inner object, in order to grant it access to the private variables. But how do we expose the inner object to the outside world? With the way the code is written in the above example, we can...
MyClass.java:5: error: name has private access in Person System.out.println(myObj.name); ^ 2 errors Instead, we use thegetName()andsetName()methods to access and update the variable: Example publicclassMain{publicstaticvoidmain(String[]args){PersonmyObj=newPerson();myObj.setName("John"...
Example #include <iostream>using namespace std;class Employee { private: // Private attribute int salary; public: // Setter void setSalary(int s) { salary = s; } // Getter int getSalary() { return salary; }};int main() { Employee myObj; myObj.setSalary(50000); cout << myObj....

To achieve encapsulation, you can define the private variables in the class and give them access to the outside world using different methods.ExampleIn the example below, we have defined the car class. The car class contains the 'brand', 'name', and 'milage' private variables....
As the example above shows, modern object-oriented languages don’t necessarily preclude the use of antiquated, procedural techniques. Bundling data and methods The code can be easily improved. For starters, why place data and the functions that operate on that data in separate modules? Java ...
For example, if you have a class called "Car" and you want to keep the car's speed private, you would declare the "speed" variable as private, like so: classCar{privateintspeed;...} Java Copy You can then provide public methods to access and modify the speed variable, known as gett...
