我遇到了char的问题

Question

我遇到网络豆子拿一个角色的问题,然后说这个人是谁和hr工资工人或每月支付任何帮助将得到一个错误的线与char

import java.util.Scanner;

public class Infromation {

    public static void main(String [] args){

        Scanner input=new Scanner(System.in);
        System.out.print("Enter employee num");
        int e_num=input.nextInt();
        System.out.print("Enter employee first name");
        String e_fname=input.next();
        System.out.print("Enter employee surname");
        String e_sname=input.next();
        System.out.print("Enter employee code C,H and F");
        char e_code=input.next();

Answer 1

char e_code=input.next();

Scanner.next()返回一个String.

如果你想让角色超出Scanner.next():

char e_code = input.next().charAt(0);
