枚举使用的语句：

import java.util.Scanner;

public class Engineers {
    public enum Level{
        L1,L2,L3
    }

    public void ceping(){
        Scanner sc=new Scanner(System.in);
        String a=sc.next();
        Level l=Level.valueOf(a);
        switch (l){
            case L1:
                System.out.println("大数据开发工程师");
                break;
            case L2:
                System.out.println("大数据挖掘工程师");
                break;
