조원끼리 쇼핑몰 만들어보기

쇼핑몰을 로그인하고 회원수정 / 상품등록 상품수정으로 나누어서 하게 됬다.

}

 

하고 유틸리티 까지 만들었다.

 

package day9;

import java.util.List;
import java.util.Scanner;

import day8.User2;

public class Utill {
	public int numberCheck() {
		int result;
		Scanner sc = new Scanner(System.in);
		while(true) {
			if(sc.hasNextInt()) {
				result = sc.nextInt();
				break;
			} else {
				System.out.println("숫자만 입력하세요");
				sc.nextLine();
			}
		}
		return result;
	}
	public String duCheck(List<Shopping>list) {
		Scanner sc = new Scanner(System.in);
		String result;
		while(true) {
			result = sc.next();
			boolean find = false;
			for(Shopping s : list) {
				if(s.getTitle().equals(result)) {
					System.out.println("중복된 아이디 입니다 다시입력>");
					find = true;
					break;
				}
			}
			if(!find) {
				break;
			}
		}
		return result;
	}
}

여기까지 만들고 조원 코드와 합쳐볼 생각이다.
