【java基础增强】带抽象方法的枚举

import org.junit.Test;

public class Demo2 {

	@Test
	public void test(){
		print(Grade.B);
	}

	public void print(Grade g){
		String value=g.localValue();
		System.out.println(value);
	}
	
	enum Grade{
		
		A("100-90"){
			public String localValue(){
				return "优";
			}
		},
		B("89-80"){
			public String localValue(){
				return "良";
			}
		},
		C("79-70"){
			public String localValue(){
				return "一般";
			}
		},
		D("69-60"){
			public String localValue(){
				return "及格";
			}
		},
		E("59-0"){
			public String localValue(){
				return "差";
			}
		};
		
		private String value;
		//定义私有构造方法
		private Grade(String value){
			this.value=value;
		}
		
		public String getValue(){
