枚举定义常量（数字-字符串）

枚举类

package com.mark.java;

public enum Color {
	红(1, "红"), 橙(2, "橙"), 黄(3, "黄"), 绿(4, "绿"), 蓝(5, "蓝");
	private final int type;
	private final String color;

	private Color(int type, String color) {
		this.type = type;
		this.color = color;
	}

	public int getType() {
		return type;
	}

	public String getColor() {
		return color;
	}

	public static String getColorName(int type) {
		for (Color c : Color.values()) {
			if (type == c.getType()) {
				return c.getColor();
			}
		}
		return "";
	}
}

测试类

package com.mark.java;

public class ColorTest {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		System.out.println(Color.getColorName(1));
		System.out.println(Color.getColorName(2));
		System.out.println(Color.getColorName(3));
		System.out.println(Color.getColorName(4));
		System.out.println(Color.getColorName(5));
	}

}

很简单，很实用！！！
