    List<Object> objects = new ArrayList<Object>();
    

    objects list will accept any of the Object

    You could design like as follows

    public class BaseEmployee{/* stuffs */}
    
    public class RegularEmployee extends BaseEmployee{/* stuffs */}
    
    public class Contractors extends BaseEmployee{/* stuffs */}
    

    and in list

    List<? extends BaseEmployee> employeeList = new ArrayList<? extends BaseEmployee>();
