Encapsulation is a process of wrapping code and data together into a single unit. Encapsulationis used to bind method and variables(data). Below is my sample code to demonstrate Encapsulation in java, in this first I have created food class and food related data - name taste, price and taste defined in String and then in next step I have created calculateCost() method , all behaviour of food bind in single unit or say calculateCost() method. In the below example I have fully described "how can use Enapsulation in java".

public class Food {

 private String name;
 private String price;
 private String taste;

 private Food(String name, String price, String taste) {
  this.name = name;
  this.price = price;
  this.taste = taste;
 }

 public void calculateCost() {

 }


 public String getName() {
  return name;
 }

 public void setName(String name) {
  this.name = name;
 }

 public String getPrice() {
  return price;
 }

 public void setPrice(String price) {
  this.price = price;
 }

 public String getTaste() {
  return taste;
 }

 public void setTaste(String taste) {
  this.taste = taste;
 }

}
