Write a program to apply encapsulation in Java.

Encapsulation is supported by class and protects codes from accidental damage by creating a wall around objects and hides their properties and methods. it is a protective (cap / cover / shield ) that prevents the data from being accessed by the code outside this shield.

class Change
{
private int l,b;
public void set(int l)
{
this.l=l;
this.b=l/3;
}
public void show()
{
System.out.println("l=="+l);
System.out.println("b=="+b);
}
}
class Client
{
public static void main(String[] args)
{
Change cc=new Change();
cc.set(70);
cc.show();
}
}

Encapsulation Output:
