Java:

• Asking users to declare multiple function signatures to match different GENERIC types is riduclous and out of scope of a 7kyu (It is also neither mentioned in the description nor clearly stated in the initial solution setup). Users can only know what signature to write based on the error feedback from tests which is not a good practice ...

Strongly suggest to revamp the test suite to just use String[] which uses natural ordering as the sorting criteria (lexicographically ordering) , same as C# , TS and other strongly typed languages

it is because you did not create a function, so there is no function to return the "hello world!" message

approved

for good practice, the description should mention that a stable sort is expected

Self-approved after almost half a decade later :-)

How bad is that? Specify iterable instead of list ( the output format currently isn't even specified ), and you allow for ( modern ) idiomatic solutions.

better instructions should be,

with descending order ;

  * dates,   2 > 1 
  * letters, A > Z 

The tests do not check stdout, they check what your function returns. So, printing anything is completely ignored by the tests.

getout the !

awesome like a potato, cut and rotate, cut and rotate.

Are there things like 9kyus?
