While you are waiting for getting help, here are some tips to improve your experience:

Code is much easier to read if posted with syntax highlighting and proper formatting.

If nobody is calling back, that usually means that your question was not well asked and hence nobody feels confident enough answering. Try to use your time to elaborate, provide details, context, more code, examples and maybe some screenshots. With enough info, someone knows the answer for sure.

Don't forget to close your thread using the command </help-thread close:1027500463647621170> when your question has been answered, thanks.

can you give an example test case which fails?

FYI you can just do

if(!diffSet.add(diff)){
    isUsable = false;
    break;
}

u can do

    loop: for (int i = 0; i < n - 1; i++) {
      for (int j = i + 1; j < n; j++) {
        int diff = Math.abs(seq[i]  - seq[j] );
        if (diffSet.contains(diff)) break loop;
        else diffSet.add(diff);
      }
    }

Technically yes but you shouldn't use labels

You could however, extract both loops into a method of their own

Which returns false inside the second loop if a duplicate us found

And returns true outside both loops(indicating no duplicates were found)
