泛型的实例

泛型的实例：

package com.james.enums;

public class EnumTest {
	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		honglvdeng deng=honglvdeng.hong;
		System.out.println(deng.next());
	}
	public enum honglvdeng{
		hong{
			@Override
			public honglvdeng next() {
				// TODO Auto-generated method stub
				return lv;
			}
		},lv{
			@Override
			public honglvdeng next() {
				// TODO Auto-generated method stub
				return huang;
			}
		},huang{
			@Override
			public honglvdeng next() {
				// TODO Auto-generated method stub
				return hong;
			}
		};
		public abstract honglvdeng next();
	}
