VO(Value Object)

package test.com.board;

public class BoardVO {
	
	private int num;
	private String title;
	private String name;
	private String content;
	
	public int getNum() {
		return num;
	}
	public void setNum(int num) {
		this.num = num;
	}
	public String getTitle() {
		return title;
	}
	public void setTitle(String title) {
		this.title = title;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getContent() {
		return content;
	}
	public void setContent(String content) {
		this.content = content;
	}
	
	@Override
	public String toString() {
		return "BoardVO [num=" + num + ", title=" + title + ", name=" + name + ", content=" + content + "]";
	}

게시판에 나타낼 요소들: num, title, name, content

DAO(Data Access Object)

package test.com.board;

import java.util.ArrayList;

public class BoardDAO {

	public int insert(BoardVO vo) {
		System.out.println("insert()...");
		System.out.println(vo);
		
		return 1;
	}
	
	public int delete(BoardVO vo) {
		System.out.println("delete()...");
		System.out.println(vo);
		
		return 1;
	}
	
	public int update(BoardVO vo) {
		System.out.println("update()...");
		System.out.println(vo);
		
		return 1;
	}
	
	public BoardVO selectOne(BoardVO vo) {
		System.out.println("selectOne()...");
		System.out.println(vo);
		
		BoardVO bvo = new BoardVO();
		
		bvo.setNum(vo.getNum());
		bvo.setTitle("BBB");
		bvo.setName("kim");
		bvo.setContent("Banana");
		
		return bvo;
	}
	
	public ArrayList<BoardVO> selectAll(){
		System.out.println("selectAll()...");
		
		ArrayList<BoardVO> vos = new ArrayList<BoardVO>();
		
		for (int i = 0; i < 30; i++) {
			BoardVO vo = new BoardVO();
			
			vo.setNum(i);
			vo.setTitle("CCC"+i);
			vo.setName("lee"+i);
			vo.setContent("Cherry"+i);
			
			vos.add(vo);
		}
		return vos;
	}
