I have been taking notes on Jamal's moderation on Code Review lately, and based on my findings, I think I'm ready to earn The Archivist. — Jamal 21 secs ago

I've made this program to do a few integer calculations. Do the methods for converting the numbers look good? Do you have any other basic tips?

Last I heard, Community Ads were something graduated sites could do... but recently I stumbled upon this meta-PCG post, so here's a shamelessly stolen meta-post :)
It's simple: you make an ad, and post it as an answer here; then the community votes for what the next ad should be.

I would like to know if this is the correct way to use try/catch when dealing with multiple MySQL queries and PDO?

$create->execute();

Get yourself a profile picture, seriously.
You don't have to put your own picture. (online safety,stalkers,..)
There are plenty of profile pictures/ generators.

The community-ads questions are created automatically by the Community user on the meta of every site that qualifies. The problem for German Language SE is that it is still in public beta. Beta sites don't get all the same bells and whistles ad graduated sites, including the Community Ads.

I was solving the project Euler's problems one by one.
I reached this problem and wrote a program which worked very well for smaller numbers.

public String join(String[] str, String separator){

You can use replace and replaceAll with regular expressions.
String[] strings = {"a", "b", "c"};
String result = Arrays.asList(strings).toString().replaceAll("(^\\[|\\]$)", "").replace(", ", ",");
Because Arrays.asList().toString() produces: "[a, b, c]", we do a replaceAll to remove the first...
Even easier you can just use Arrays, so you will get a String with the values of the array separated by a ","
String concat = Arrays.toString(myArray);
so you will end up with this: concat = "a,b,c"
It seems that input.getClass() returns ModelConvertersFacadeTests
That is not true. Your stacktrace says this is the class:

With Java 1.8 there is a new StringJoiner class - so no need for Guava or Apache Commons:
String str = new StringJoiner(",").add("a").add("b").add("c").toString();
Or using a collection directly with the new stream api:
String str = Arrays.asList("a", "b", "c").stream().collect(Collectors.joi...
Using Java 8 you can do this in a very clean way:
String.join(delimiter, elements);
This works in three ways:
//directly specifying the elements
String joined1 = String.join(",", "a", "b", "c");
//using arrays
String[] array = new String[] { "a", "b", "c" };
String joined2 = String.join(",",...
