    Just

    List objects = new ArrayList();



    or so?
    


    I wouldn't recommend this approach though. The data must be somehow related to each other. Why would you make it hard for yourself and mix different types of data in a collection? What do you need it for at end? Just passing it around through layers? You could also just create a custom javabean object for this (also known as value object or data transfer object). Something like:
    


    public class Data {
    private Double double1;
    private Double double2;
    private int int1;
    private int int2;
    private Calendar calendar;
    // Add/generate getters and setters.
}
