From my previous post, we have discussed on how to convert an array to arrayList in java. On this section it would be the other way around because we will be showing how to convert ArrayList to array in java.
There might be a question on your mind, why we have to do this? Well the answer to this is very simple, as you may know there are some scenarios where the output of a java API method is in ArrayList format and our business requirements is expecting an array, thus this tutorial was made for the sole purpose of converting ArrayList to array in java programming.
It is worth to mention that even though our business requirements or desired output an Array, we may opt to use put our values first on a container such as ArrayList to enjoy the powerful methods on this Object such as sorting. Moreover the ArrayList object has dynamic contents. We need to have a container that support dynamic contents in merging multiple arrays, delete specific element on our collection before converting back to an array of elements. Thus the conversion from an array to ArrayList and vice versa is a must to learn.
