Hello Friends

I tried finding the way to achieve the following but could not, could you please assist me in doing the following

1. I have two arrays Target and Source
2. I want to copy Source Array into Target Array starting from the given indices of Target Array.

Assume Target Array size >= Source Array

Fill method in Arrays class gives me an opportunity to add like this
Arrays.fill(target, 3, 6, 50);
which will add with all 50s starting from position 3

I want something like

Arrays.fill(target, 3, source);
so that it copies all the elements of Source to target starting from position 3;

Thanks and Warm Regards

Hello Geeks

I have a Circle as a BITMAP and my requirement is to know which screen coordinates the circle peripheral is covering and to know when someone touches the same and not the touch inside circle.

In general, how to get the screen coordinates the bitmap is covering ??

Context : Android
Problem : There are many "Brands" like mufti , levis , blackberry and so on. Each Brand contains Various categories like Jeans, t-shirts and so on.
As a user i want to select the Brand and then the Category and then want to see the various items in a particular category . These items will be shown in a VIEWPAGER wherein the user can swipe and see various items.


Present Solution : I am using ViewPager and it requires an instance of PagerAdapter which sends the Page in accordance to the position.

I extended PagerAdapter with mine "MyAdapter". MyAdapter class contains various if-else statements which decides the page to send back to "ViewPager" in accordance to the item and category chosen by a user.

So i tried cleaning up my code and ends up as follows

I created class hierarchy as follows

BaseAdapter
MuftiAdapter extends BaseAdapter
LevisAdapter extends BaseAdapter

and so on so forth....

MuftiAdapter knows about what to return in its various possible categories. Levis know its own....
I created one AdapterFactory which provides me the right instance.


AdapterFactory now decides which instance to return depending upon the BRAND and CATEGORY.


Someone asked me what iff there are 100 BRANDS , will you make 100 classes for the same which extends BaseAdapter ?

I am not sure whether my above design is right or wrong ??? Is there any better design in this case when number of brands are very high.???

Thanks and Regards
