How would i preform the tasks below in android studio?

1) Create a one dimensional array with 12 elements 2) set the first array values to be one 3) set every following array value to be the sum of the two before it 4) walk through the array and add up every element >= 10. 5) display the result as a toast message

I am having trouble doing this. I am very new to the android software and it would be great for some help.
