Program: How to call enum, which is defined inside a class?
Description: |
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.
|
Code: |
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
}
}

Java class can be private?
We can not declare top level class as private. Java allows
only public and default modifier for top level classes in java.
Inner classes can be private.
