Answer to Question #249462 in Java | JSP | JSF for Ashwari Pillay

Question

Write a java program where a user enters and stores the average monthly rainfall figures (int) for three (3) towns over a year. The rows represent the months, and the columns represent the towns.

Calculate and print the total rainfall figures for each town, and the average rainfall for each month. Use a switch statement to print out the month name according to the column subscript value (E.g. if col = 0, then print January, col = 1 then print February, etc.) with the corresponding total alongside it.
