Encapsulation:
Encapsulation is the process of wrap the data and
code into single unit. The variables of a class will be hidden from other
classes, and can be accessed by methods of their current class.
Make encapsulation in following way.
1. Declare variables as private.
2. Declare public setter and getter methods to
access or modify the value.
Example:
public class Employee {
private
int id;
private
String name;
private
int age;
public
int getId() {
return
id;
}
public
void setId(int id) {
this.id
= id;
}
public
String getName() {
return
name;
}
public
void setName(String name) {
this.name
= name;
}
public
int getAge() {
return
age;
}
public
void setAge(int age) {
this.age
= age;
}
}
