Answer 1

Try fixing the connection string:

Connection myConn = DriverManager.getConnection(" jdbc : mysql ://localhost:3306/world","root","1234")

Answer 2

Looks like you have semicolon for the sql statement,

Below is the correct one.

ResultSet myRs = myStmt.executeQuery("SELECT * FROM world.city");
