a) What field does every array object have?

Answer: Every array in java contain a final field that is length. length is the property that will give the number of elements in array.

b) Suppose you have this code:  double[   ] temperatures = new double[12];

Write the lines of code to triple the capacity of the array

Answer:

     double[ ] temperatures = new double[12];

   temperatures = Arrays.copyOf(temperatures , temperatures.length * 3);
