Package Com.cqvie.Hello;

Class Person

{

private int age;

private String name;

public void Tell ()

{

System.out.println ("Name:" +name+ "" + "Age:" +age);

}

public int Getage ()

{

return age;

}

public void Setage (int.)

{

This.age = age;

}

Public String GetName ()

{

return name;

}

public void SetName (String name)

{

THIS.name = name;

}

}

public class Testdemo

{

public static void Main (string[] args)

{

Person per = new person ();

Per.setname ("Zhang San");

Per.setage (19);

Per.tell ();

}

}

This program is a fairly simple piece of code that encapsulates a property, defines a private age,name property for the person class, and includes a tell () method with no return value.

Because of the non-accessibility of the private property, a heap of getter (), setter () methods are generated, thus completing a simple encapsulation.
