1. (5 pts) Given an integer array: int A[] = new int[10]; It is easy to print values of array elements from the first one to the last one by using a for loop. Can you use a for loop to print those values from the LAST array element to the FIRST array element? (i.e. print values in the reversed order). 2. (2pts) What is a recursive method? 3. (2pts) What are important factors when designing a recursive method? 4. (2pts) is the following method recursive method? If it is, are there any design flaws? What are those flaws? public static void ABC(int x) { System.out.println(x); } ABC(x); 5. (4 pts) Finish the method below. It converts a Celsius temperature (which is passed as a method parameter "celsius") to a Fahrenheit temperature. The method returns the Fahrenheit result in floating point number. The conversion formula is: F = (9.0/5.0) X C + 32 public static } cToF(double celsius) { 6. Review our course example Dice.java (in Week13&14 folder) and answer the following questions. 6.1. (2pts) Have we defined any member variables in the Dice class? If yes, what are they? 6.2. (2pts) What modifiers we used to define those variables? (public? private?) Why we use that specific modifier? 6.3. (2pts) Have we defined any member methods in the Dice class? If yes, what are they? 6.4. (2pts) How would you call those methods?
