Encapsulation in Java - Data Hiding

Encapsulation

Encapsulation is the process of wrapping code and data together into a single unit.

How to achieve:

Declare variables of a class as private.

Provide public setter and getter methods to modify and view the variables values.

public class Person {
  private String name; // restricted access
  // Getter
  public String getName() {
    return name;
  }
  // Setter
  public void setName(String newName) {
    this.name = newName;
  }
}
