I cannot connect to MySQL database

I cannot connect to MySQL database. It happened after updating MySQL and JDK. I added useSSL=false, but no result. This is the exception I get from eclipse:

Establishing SSL connection without server's identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.

package card;

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

public class Database {
    private staticConnection con = null;

    public Database()
    {

    }

    public static Connection connect() throws SQLException, InstantiationException, IllegalAccessException, ClassNotFoundException
    {
        return con=java.sql.DriverManager.getConnection("jdbc:mysql://localhost:3306/gym?u‌​seSSL=false", "root", "1234");
    }
}

You will also need to set useSSL to true in your connection parameters for MySQL

So replace "useSSL=false" to "useSSL=true" like this

jdbc:mysql://localhost:3306/gym?u‌​seSSL=true
