java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/tun_recrut -

i'm new in java , i'm trying make simple authentication interface.

i trying execute simple query using drivermanager . can please me understand issue here ?

1/ mydbconnection.java

package com.esprit.tunrecrut.util;      import java.sql.connection;     import java.sql.drivermanager;     import java.sql.sqlexception;     import java.util.logging.level;     import java.util.logging.logger;           public class mydbconnection {              /**              * déclaration des variables pour la connexion              */             private string url = "jdbc:mysql://localhost:3306/tun_recrut";             private string login = "root";             private string pwd = "";             private static mydbconnection instance;             public static connection connection;              private mydbconnection() {                 try {                     connection = drivermanager.getconnection(url,login,pwd);                  } catch (sqlexception ex) {                     logger.getlogger(mydbconnection.class.getname()).log(level.severe, null, ex);                 }             }              public static connection getconnection() {                 return connection;             }              public static mydbconnection getinstance() {                 if(instance==null)                     instance = new mydbconnection();                 return instance;             }           } 

2/crud.java

package com.esprit.tunrecrut.util;  import java.sql.resultset; import java.sql.sqlexception; import java.sql.statement; import java.util.logging.level; import java.util.logging.logger;   public class crud {      mydbconnection mc = mydbconnection.getinstance();      public boolean execute(string sql){         try {             statement statement = mc.getconnection().createstatement();             statement.executeupdate(sql);             return true;         } catch (sqlexception ex) {             logger.getlogger(crud.class.getname()).log(level.severe, null, ex);             return false;         }     }      public resultset exeread(string sql){         try {             statement statement = mc.getconnection().createstatement();             resultset rs;             rs = statement.executequery(sql);             return rs;         } catch (sqlexception ex) {             logger.getlogger(crud.class.getname()).log(level.severe, null, ex);             return null;         }      }   } 

in userdao.java

public user finduserbyemailandpassword(string email, string password) {        user user=null;     try {         string sql = "select * user email_address = '" + email + "' , password = '" + password + "'";         resultset rs = crud.exeread(sql);         while (rs.next()) {              user = new user(rs.getint("id"), rs.getstring("type"), rs.getstring("email_address"));          }         return user;      } catch (sqlexception ex) {         logger.getlogger("client controller").log(level.severe, " fail");        // logger.getlogger("client dao").log(level.severe, null, ex);         return null;     } }
