sql의 테이블 확인하고 

vo의 필드(전역변수) 세팅

필요한 값들을 필드에 넣기

package com.kh.test.model;

import java.sql.Date;

public class Test {
	
	public int seq;
	public String writer;
	public String title;
	public String content;
	public Date regDate;
	
	public Test() {}

	public Test(int seq, String writer, String title, String content, Date regDate) {
		super();
		this.seq = seq;
		this.writer = writer;
		this.title = title;
		this.content = content;
		this.regDate = regDate;
	}

	
	public int getSeq() {
		return seq;
	}

	public void setSeq(int seq) {
		this.seq = seq;
	}

	public String getWriter() {
		return writer;
	}

	public void setWriter(String writer) {
		this.writer = writer;
	}

	public String getTitle() {
		return title;
	}

	public void setTitle(String title) {
		this.title = title;
	}

	public String getContent() {
		return content;
	}

	public void setContent(String content) {
		this.content = content;
	}

	public Date getRegDate() {
		return regDate;
	}

	public void setRegDate(Date regDate) {
		this.regDate = regDate;
	}
	
	

}

실행 클래스(런파일, 메인메소드)

package com.kh.example.practice4.run;
import com.kh.example.practice4.model.vo.Book;

public class Run {

	public static void main(String[] args) {

		Book b1 = new Book();
//		b1.inform();
				
		Book b2 = new Book("책1","출판사1","저자1");
//		b2.inform();
			
		Book b3 = new Book("책2","출판사2","저자2",10000,0.3);
		b3.inform();
				
	}
}
