Arraylist index calculation java

Question

I have array list that each indexes has value either 0 or 1.I want to find that continuously three indexes has the value 1.How do I find it?

Answer 1

Without actual code:

1. iterate thorough the array
2. count the 1s you found
3. if you found a 0 then start over the count
4. check after increasing the counter: if the counter reaches 3 then return with true
5. if you reached the end of the array and no more elements then return with false

Something like this, I hope I could help.
