How to keep all the data from different Jframes in one object in java GUI

Question

I am making a GUI and I have almost 10 frames each accepts data from user. I want to save this data in one object. I am wondering how to do that.like you make one object in main and access all the functions from there and store all the data in this one object.

Don't create multiple jframes. Reuse the same one. Create multiple `JPanel`. Use tabbed panels if you want all the screens at the same time. — Sorter, Jan 08 '15 at 09:31
Actually I have 2 classes one road(edges) and one city(vertex) and a Graph class that access both classes. I want to work with only Graph class object. All I want is that when i press submit button in different places all data should be stored in one object. — Faiqa Babar, Jan 08 '15 at 09:37

If the all data are "related to one object," you can make a class to represent this object; either

make the class static, with all elements inside it

or make the class a singleton

public class ClassicSingleton {
    private static ClassicSingleton instance = null;
    protected ClassicSingleton() {
        // Exists only to defeat instantiation.
    }
    public static ClassicSingleton getInstance() {
        if(instance == null) {
            instance = new ClassicSingleton();
        }
        return instance;
    }
}
