Explanation of “SentinelDemo.java”: Refer the “SentinelDemo.java” in textbook which describes about the calculation of average of salary. In this program , Read the salary values until the user presses the sentinel value of “-1”. Iterate the loop until the value of salary is “-1”. Check whether the salary is in “double” type. If the salary is not equal to sentinel value “-1”. Then, calculate the sum for loop iteration. Check if the count is greater than “0”. If yes, then calculate the average of the salary. Print the average of the salary. Otherwise, print “no data”.
