Question

Is there a Ruby version of for-loop similar to the one in Java/C(++)?

In Java:

for (int i=0; i<1000; i++) {
    // do stuff
}

The reason is because I need to do different operations based on the index of the iteration. Looks like Ruby only has a for-each loop?

Am I correct?

Yes you can use each_with_index

collection = ["element1", "element2"]
collection.each_with_index {|item,index| puts item; puts index}

the ‘index’ variable gives you the element index during each iteration
