Sorry, it's fixed now!

The result should be rounded to two decimal places.

I don't see the issue...

The test case are just for testing your code before submitting.

If you build a calculator, a test case could test to ensure that 1+1 returns 2

A test case is NOT required for passing the challenge. They are for testing only. One does not need to test if you know what you're doing

You could write one. Or if you're good enough, don't use the test case, just submit once your code is logically correct.

You dont need to type anything in the test cases. Those are for testing. There are test cases written for when you submit it.

I ocmpleted this challenge with no effort, using Java. So I know it's not broken.

Theres more too it than that bud. Follow the logic. You're saying everything that's not 0 and divisable by 3 is Java.

What about Coffe, CoffeeScript, and Javascript?

if (n != 0) {
      if (n%3==0 && n%4 != 0) {
        if(n%2==0)  {
          return "JavaScript";
        }
        else {
          return "Java";
        }
      
      }  // not devis 4
      
      else if (n%3==0 && n%4==0) {
        if(n%2==0) {
          return "CoffeeScript";
        }
        else {
          return "Coffee";
        }
        
      } // devise form  
          
    } // MAIN IF
    
    
    return "mocha_missing"; // ELSE!!!!!!!!!!!!!!!!!!

When you mark an issue you have to point out the mistakes. Anyway your observation made me review the grammar and orthography of the the kata and I found a better way to express the content in two sentences. You suggestions are welcome. Feel free to send them, please

What is your issue?

Is not a fundamental question

The person has bad grammer

What is a test case?

Terrible, terrible. Mot instructions given to round.
