i want to check if the username given by user is my database (Mysql workbench) or not thus i wrote the method like

    {
        while(rs.next())
        {
            if(rs.getString(1).equals(username))
            {
                System.out.println("already exsist");
                System.out.println("Please enter another name:");
                username = s.nextLine();
                checkUsernameExist(rs,username);
            }
        }
    }```

i recursively called the same method until i get a unique name from the user. My problem is when i call the method 'checkUsernameExist' the parameter rs wants to be re-initialized or move one step upward in the table. What should i do now?

& This is what i got

Enter the username: 
name
already exsist
Please enter another name:
name
already exsist
Please enter another name:
name

i want to continue my loop until i get a unique name
