Optimal Solution to Split a Comma-Separated String into an ArrayList

When faced with the task of parsing a string with an unknown length containing comma-separated values, the question arises: how can we efficiently convert this into an ArrayList, where each word becomes an element?

The Optimal Approach

The most effective way to achieve this is through the ingenious .split() method:

String str = "...";
List<String> elephantList = Arrays.asList(str.split(","));

1. .split() Mastery: This method performs a wizardry of sorts, breaking down the string into an array of strings utilizing the delimiter provided. In this scenario, the delimiter is the comma (,).
2. Arrays.asList() Conversion: To match your desired output, we employ the Arrays.asList() utility, seamlessly transforming the array into a List of strings.
3. Practice Excellence: A subtle improvement worth noting: programming to an interface (e.g., List) is recommended over the direct use of the concrete implementation (ArrayList). This aligns with best practices and promotes flexibility.
