[Solved] Is there a more elegant way to splitting string and datatype conversion with Java?

Question

I finished Java courses not long ago and trying to solve code coach challenge.

When I hit Balconies the question is supplying a comma separated string. And to complete the task those elements need to be converted into integer.

The code below is how I solved the problem, but I found it is much cumbersome than python.

Is there an elegant way to accomplish the same task?

Answer 1

In addition to your own solution, which is also perfectly fine, here are some more ideas:
- Stream
- Scanner
- regex (Pattern and Matcher)

Examples in this code:

My code is not a solution for the code coach, but you may find a few more possible ways there, how to compare the numbers and display the results.

You examples are very helpful, especially the Stream method. It is like "with" in VBA, while inside it is like a lambda function, but in a whole it is like working on a while loop with iterable object.

I think I will save regex for later. I did occasionally use regex in code coach with python, but not often.

Wong Hei Ming Java is just inherently verbose. Kotlin is it's cool brother.

I was looking into using lambda expression for your problem, but in Java, it turned out to be longer and more convoluted than your clean solution...😅

Kotlin's lambda and closure is a bit better.
