如何初始化来自不同类的各种数据类型成员值？

Question

I have a public class named as ABC. There are various types of variables declared with the getter and setter method along with that.

Those values will be coming from various other classes.

What will be the best approach to initialize those data types?

I can go with making that class as singleton.I don't want to create multiple object for that class.

The values which will be coming from classes are B,C,D,E.

If i create a singleton object in B and pass that with the Intent to C,D,E and assign remaining values will that be the best approach ?

OR

creating a public static object as a constant.and access that object from different classes and store variable.

OR

is there any other better approach ?

Please advice. [Please Note: Coding is for Android]

Answer 1

I would go for the singleton approach

public class ABC
{
    private static ABC instance;

    private String memberVar;

    private ABC()

    public static ABC getInstance()
    {
        if (instance == null) {
            instance = new ABC();
        }
        return instance;
    }
}

Then you can access it from the other classes via ABC.getInstance().yourGetter()
