• first part: duplicate of this issue
• second part is unclear:
  • "Final test is incorrect" -> how so ? can you provide an example ?
  • "Assertions aren't even on for whatever reason" what does that mean ? please be more precise

The true/false test is testing if the length of your code is <=161 characters for the challenge.

It means your code is longer than specified in the challenge. Agreed, unhelpful but that's what it means.

Many many errors

Outdated/deprecated usage of new Integer()

Remove this entirely, simply use ints.

Final test is incorrect

Assertions aren't even on for whatever reason

Note: src/test/java/TipCalculatorTest.java uses or overrides a deprecated API.
Note: Recompile with -Xlint:deprecation for details.

Java: the countChar test assertion message is very unhelpful (expected: <true> but was: <false>)

Your task is to shorten the code as much as possible in order to meet the strict character count requirements of the Kata. (no more than 161) You may assume that all array elements are unique.

your code is correct but too long

Your task is to shorten the code as much as possible in order to meet the strict character count requirements of the Kata. (no more than 161)

this is what the countChar test does, although I agree that the assertion message is really poor. your current code has 394 characters

You can't just import apache on a kata 😭

Those numbers are the length of a side of a square. A square can be defined with only one number because all sides have the same length.

You will return a collection or a string (depending on the language; Shell bash, PowerShell, Pascal and Fortran return a string) with the size of each of the squares.

Infinite loop overloading their code runner, run it on your computer to help see what's making the loop
