[Resolvido]Erro ao tentar conectar com o mysql

Estou desenvolvendo um projeto com Java Web e Mysql e quando fui criar a conexão e testar esta dando bastante erro, preciso de ajuda para resolver isso…

package br.com.farmacia.factory;

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

public class Conexao {
	private static final String USUARIO = "root";
	private static final String SENHA = "admin";
	private static final String URL = "jdbc:mysql://localhost:3306/cafeteria?useSSL=false&serverTimezone=UTC";

	public static Connection conectar() throws SQLException {
		Connection conexao = DriverManager.getConnection(URL, USUARIO, SENHA);
		return conexao;
	}

	public static void main(String[] args) {
		try {
			Connection conexao = Conexao.conectar();
			System.out.println("Conectado com Sucesso !!");
		} catch (SQLException e) {
			e.printStackTrace();
			System.out.println("Conexão falhou !!");
		}
	}
}

Erros que estão acontecendo
