No suitable driver found for jdbc

import org.junit.Test;
import java.sql.*;
public class jdbc {
    @Test
    public void demo(){
        try {
            // 1、加载驱动程序
            Class.forName("com.mysql.cj.jdbc.Driver");
            //2、创建连接
            Connection imooc = DriverManager.getConnection(
                    "jdbc:mysql//192.168.3.7:3306/imooc"+
                            "?useSSL=false&serverTimezone=Hongkong&useUnicode=true&characterEncoding=utf-8",
                    "root","zhy632746542");
            //3、创建进行SQL解析的对象
            String select = "select * from news";
            Statement sql = imooc.createStatement();
            ResultSet set = sql.executeQuery(select);
            while (set.next()) {
                int id = set.getInt("id");
                String title = set.getString("title");
                String content = set.getString("content");
                System.out.println("id"+" "+id+" "+"title"+title+""+"content"+content);
            }
            //4、释放资源
            set.close();
            sql.close();
            imooc.close();
        } catch (SQLException e) {
            e.printStackTrace();
        }catch (ClassNotFoundException e) {
            e.printStackTrace();
        }
    }
}

下面是报错
