MySQL 워크 벤치를 Eclipse에 연결하기

Question

프로그래밍하기가 너무 쉽습니다. 이클립스 프로젝트에 MySQL 워크 벤치를 연결하려고하는데 어디서부터 시작해야할지 모르겠다. 누군가가 내가해야 할 과정을 설명해 주실 수 있습니까? 어떻게 구현할 것인가?

감사합니다.

package com.example.sql; 

import java.sql.DriverManager; 
import java.sql.Connection; 
import java.sql.PreparedStatement; 
import java.sql.ResultSet; 
import java.sql.SQLException; 

public class JDBCExample { 
    public static Connection con; 
    public static void main(String[] argv) { 
     try 
     { 
      connectionQuery(); 

      PreparedStatement statement = con.prepareStatement("SELECT * from table_name");/*write query inside of prepared statement*/ 
      ResultSet result = statement.executeQuery(); 
      System.out.println("DataBase table accessed"); 

      while(result.next()) 
      { 
       String retrievedid= result.getString("Column_name"); 

       System.out.println(retrievedid); 
      } 


      con.close(); 
     } 

     catch(Exception e) 
     { 
      e.printStackTrace(); 
      System.out.println(e.getMessage().toString()); 
     } 
    } 

    public static void connectionQuery() 
    { 
     try 
     { 
      Class.forName("com.mysql.jdbc.Driver");
