개발일지 17일차 -class 역할 분리 응용-

오늘은 지난시간에 이어서 class 역할 분리를 응용하여 회원가입 , 정보 수정 ,회원 탈퇴 , 로그아웃, 중복확인 등을 구현해보았다

package ch11_classes.ex3;

public class memberDTO {
    private  Long id;
    private String memberEamil;
    private String memberPassword;
    private String memberName;
    private String memberMobile;

    public void setId(Long id) {
        this.id = id;
    }

    public void setMemberEamil(String memberEamil) {
        this.memberEamil = memberEamil;
    }

    public void setMemberPassword(String memberPassword) {
        this.memberPassword = memberPassword;
    }

    public void setMemberName(String memberName) {
        this.memberName = memberName;
    }

    public void setMemberMobile(String memberMobile) {
        this.memberMobile = memberMobile;
    }

    public Long getId() {
        return id;
    }

    public String getMemberEamil() {
        return memberEamil;
    }

    public String getMemberPassword() {
        return memberPassword;
    }

    public String getMemberName() {
        return memberName;
    }

    public String getMemberMobile() {
        return memberMobile;
    }
    public memberDTO(){

    }

    private static Long idValue = 1L;
    public memberDTO(String memberEamil , String memberPassword , String memberName , String memberMobile){
        this.id = idValue++;
        this.memberEamil = memberEamil;
        this.memberPassword = memberPassword;
        this.memberName = memberName;
        this.memberMobile = memberMobile;
    }

    @Override
    public String toString() {
        return "memberDTO{" +
                "id=" + id +
                ", memberEamil='" + memberEamil + '\'' +
                ", memberPassword='" + memberPassword + '\'' +
                ", memberName='" + memberName + '\'' +
                ", memberMobile='" + memberMobile + '\'' +
                '}';
    }
}

기본 필드이다

회원의 이메일

비밀번호

이름

전화번호를 입력 받도록 만들었고

id 는 arrayList에 넣을것이기에 Long 타입으로 해주었다

 

 

<MAIN>

package ch11_classes.ex3;

import java.util.Scanner;

public class memberMain {
    public static void main(String[] args) {
        memberService memberService = new memberService();

        Scanner scanner = new Scanner(System.in);
        int selecNo = 0;
        boolean run = true;
        while (run){
            System.out.println("1.회원가입 | 2.로그인 | 3.회원 목록 조회 | 4.회원 정보 수정 | 5.회원탈퇴 | 6.로그아웃 | 0.종료");
            selecNo = scanner.nextInt();
            if (selecNo == 1){
                memberService.memberJoin();
            } else if (selecNo == 2) {
                memberService.memberLogin("","");

            } else if (selecNo == 3) {
                memberService.findAll();

            } else if (selecNo == 4) {
                memberService.memberUpdate();

            } else if (selecNo == 5) {
                memberService.memberDelete();
                
            } else if (selecNo == 6) {
                memberService.memberLogout();
            } else if (selecNo == 0) {
                System.out.println("종료합니다");
                break;
            }
        }
    }
}

 

각각의 번호를 입력하면 그에 맞는 메서드가 실행되게 만들어주고 0번을 입력하면 종료

각 상황에 따른 메서드 이다 

기존에 배웠던 회원가입 , 로그인 , 목록 출력, 정보 수정 , 정보삭제등을 활용하였다

 

이전에 배웠던 내용에 추가된 부분은 주석을 참조
