Creating inner class example

This is an example of how to create an inner class. In short, to create an inner class we have performed the following steps:

• We have created a class CreatingInner that contains two inner classes, Contents and Destination.
• Contents class has a method value() and Destination class has a constructor using a String field and a method readLabel().
• CreatingInner class has a method ship(String dest), that creates new instances of its inner classes.
• We create a new instance of CreatingInner class, and call its ship(String dest) method to create new instances of the inner classes too.

Let’s take a look at the code snippet that follows: 

package com.javacodegeeks.snippets.core;

public class CreatingInner {

    public static void main(String[] args) {

  CreatingInner p = new CreatingInner();

  p.ship("Athens");
    }

    class Contents {


  private int i = 11;


  public int value() {


return i;

  }
    }

    class Destination {


  private String label;


  Destination(String whereTo) {


label = whereTo;

  }


  String readLabel() {


return label;

  }
    }

    // Using inner classes looks just like
    // using any other class, within Parcel1:
    public void ship(String dest) {

  Contents c = new Contents();

  Destination d = new Destination(dest);

  System.out.println(d.readLabel());
    }
}

  
This was an example of how to create an inner class in Java.
