Please guide on how to take decimal values in this proggram's output as well.Question 1 A programmer creates the Java class shown on the facing page, representing a numeric dataset read from a file. The class has a constructor that creates an object containing the data from the file, given the name of that file as a string. It also has a method called mean that returns the arithmetic mean value of the stored data. The questions that follow concern this class. You may include small fragments of code in your answers if appropriate, but you should not reimplement the class. Keep in mind that full marks can be obtained with purely descriptive answers. (a) The class as shown here will not compile. The compiler identifies two issues that need to be fixed, one occurring in the constructor and the other within the mean method. Explain what the issues are and describe how you would fix them. (b) Another programmer who is reviewing the code describes line 6 as 'dangerous'. What possible reason might there be for this comment, and how could you modify the code to fix the…
