Enum的switch用法

public enum Fruit
{
	APPLE, BANANA, ORANGE, WATERMELON
}

public class EnumTest
{
	public static void main(String[] args)
    {
		for(Fruit fruit : Fruit.values())
		{
			test(fruit);
		}
    }
	
	public static void test(Fruit fruit)
	{
		switch (fruit)
        {
			case APPLE:
				System.out.println("This is an apple");
				break;
			case BANANA:
				System.out.println("This is a banana");
				break;
			case ORANGE:
				System.out.println("This is an orange");
				break;
			case WATERMELON:
				System.out.println("This is a watermelon");
				break;

			default:
				break;
		}
	}
}
