Definition : Encapsulation in java is a technique of wrapping code i.e knowledge (Variables) and and processes carried out on that knowledge i.e strategies collectively right into a single unit referred to as class. For instance capsule i.e. blended of a number of medicines.
- In encapsulation, the variables or knowledge of a category is hidden from some other class and will be accessed solely by any member operate of personal class by which they’re declared.
- We will additionally use getter and setter strategies to get and set knowledge in it.
- As in encapsulation, the information in a category is hidden from different lessons, so additionally it is referred to as data-hiding.
- Encapsulation will be achieved by: Declaring all of the variables within the class as personal and writing public strategies within the class to set and get the values of variables.
Instance :
public class Encapsulation {
personal String title;
personal int rollno;
String getName() {
return title;
}
void setName(String title) {
this.title = title;
}
int getRollno() {
return rollno;
}
void setRollno(int rollno) {
this.rollno = rollno;
}
public static void essential (String[] args){
Encapsulation e = new Encapsulation();
e.setName(“nandini”);
e.setRollno(100);
System.out.println(e.getName());
System.out.println(e.getRollno());
}
}
