How can ı solve Exception in thread "main" java.lang.ClassCastException solve?

When I remove Connection netbeans say me "You should add Connection cast" but after add, it gives me class cast exception.

How can ı solve this.

>Solution :

The exception tells all

The DriverManager.getConnection returns a java.mysql.connection or more specifically a com.mysql.cj.jdbc.ConnectionImpl when using Mysql

And you have imported a com.sun.jdi.connect.spi.Connection which is nothing related to

Use the right import and it’ll be good

import com.mysql.cj.jdbc.ConnectionImpl; // REMOVE
import java.mysql.Connection;            // ADD
