Encapsulation in JAVA

• Binding Data(variable) and code together(Method)
• It restrict direct Access to Data
• Controls access through Getter and Setter methods

=> Why Encapsulation

• Prevents data from unauthorised access
• Ensures security
• maintainability

=> Super class
public class Joyalukkas
{

private int price=1000;

public int getprice()
{
return this.price;
}


public void setprice(int price){
this.price=price;
}

}

=> Sub class
public class Buyer
{

public static void main (String[]args)
{

Joyalukkas joyalukkas=new Joyalukkas();
System.out.println(joyalukkas.getprice());
}
}

OUTPUT:

=> Getter Method

• Getter method is a public method used to read the value of private variable from outside of the class

=> Setter Method

• Setter method is a public method used to modify the value of private variable from outside of the class
