Program: How to call enum, which is defined inside a class?

This example defines a basic enum type called Fruit inside a class. This example shows how to call enum constants defined under another class. If you declare Enum is a member of a class, then by default it is static. You can access it with reference to enclosing class.

package com.java2novice.enums;

public class MyEnumInsideClass {
	
	private MyWrapper.Fruit myFruit;
	
	public MyEnumInsideClass(MyWrapper.Fruit fruit){
		this.myFruit = fruit;
	}
	
	public void getFruitDesc(){
		
		switch (myFruit) {
	        case GRAPE:
	            System.out.println("A grape is a non-climacteric fruit.");
	            break;
	                
	        case APPLE:
	            System.out.println("The apple is the pomaceous fruit.");
	            break;
	                     
	        case MANGO: 
	            System.out.println("The mango is a fleshy stone fruit.");
	            break;
	         
	        case LEMON: 
	        	System.out.println("Lemons are slow growing varieties of citrus.");
	            break;
	            
	        default:
	            System.out.println("No desc available.");
	            break;
	    }
	}
	
	public static void main(String a[]){
		MyEnumInsideClass grape = new MyEnumInsideClass(MyWrapper.Fruit.GRAPE);
		grape.getFruitDesc();
		MyEnumInsideClass apple = new MyEnumInsideClass(MyWrapper.Fruit.APPLE);
		apple.getFruitDesc();
		MyEnumInsideClass lemon = new MyEnumInsideClass(MyWrapper.Fruit.LEMON);
		lemon.getFruitDesc();
		MyEnumInsideClass guava = new MyEnumInsideClass(MyWrapper.Fruit.GUAVA);
		guava.getFruitDesc();
	}
}

class MyWrapper{
	
	enum Fruit {
	    GRAPE, APPLE, MANGO, LEMON,GUAVA 
	}
}

A grape is a non-climacteric fruit.
The apple is the pomaceous fruit.
Lemons are slow growing varieties of citrus.
No desc available.
