public int[] makeEnds(int[] nums) {
  new int[]{nums[0],nums[nums.length-1]};
}

when i write as above getting  elow error

Compile problems:


Error:      new int[]{nums[0],nums[nums.length-1]};
                                           ^
Syntax error, insert "AssignmentOperator ArrayInitializer" to complete Expression


see Example Code to help with compile problems

please advise.

We do not need to do length check in if loop right ?

Without the return, there would be an error.

why the error message is too vague. There is no information which says this error is due to missing 'Return' like that instead says


insert "AssignmentOperator ArrayInitializer" to complete Expression

You could make the line compile by inserting an assignment:
  nums = new int[]{nums[0],nums[nums.length-1]};

(but there still needs to be a return somewhere in the function)
