TASK 3 Write a Java method that returns the location of the largest element in a two-dimensional array. public static int) locatelargest(double[] a) The return value is a one-dimensional array that contains two elements. These two elements indicate the row and column indices of the largest element in the two-dimensional array. Write a Java test Program that prompts the user to enter a two- dimensional array and displays the location of the largest element in the array. Here is a sample run: Enter the number of rows and columns of the array: 3 4 -Enter Enter the array: 23.5 35 2 10 Enter 4.5 3 45 3.5 |-Enter 35 44 5.5 9.6 -Enter The location of the largest element is at (1, 2)
Complete the following Programming Assignment. Use good programming style and all the concepts covered to date. Submit the java file(s) electronically through Canvas by the due date via one (1) Zip file. Rainfall Class - Note: Do not write a class as specified regarding the array (below). Instead use two one-dimensional arrays of size 12 each (parallel arrays) and four methods to solve the problem as specified. One array will hold the names of the months and the other array will hold the rainfall in inches for the months. You will pass the appropriate array or arrays to the methods as needed. 1. Rainfall Class Write a RainFall class that stores the total rainfall for each of 12 months into an array of doubles. The program should have methods that return the following: • the total rainfall for the year • the average monthly rainfall • the month with the most rain • the month with the least rain Demonstrate the class in a complete program.

JAVA PROGRAMMING - Create a class whose main() holds an array containing 10 integers. Create two methods that accepts the array. The first method named lowest returns the lowest from the 10 numbers while the second method named highest returns the highest number from the list. Determine the highest and lowest number without sorting the numbers. Your output should contain the original list of numbers, the highest and the lowest number from the list. Supply the necessary values for the array
