The course is Computer Science 2, Java code:

See the attached for question. Use the double array given below and the skeleton of demo should look like the following. public class Array Operations2DDemo public static void main(String[] args) double[][] darray = { { 98.7, 89.2, 55.1, 78.6 }, { 77.6, 99.9, 62.2, 54.3 }, { 63.6, 59.7, 85.6, 79.2 } }; System.out.println(" Processing the double array."); System.out.printf("Total : %.2f ", Array Operations2D.getTotal(darray)); System.out.printf("Average : %.2f ", Array Operations2D.getAverage(darray)); System.out.println("Total of row 1 :" + Array Operations2D.getRowTotal(darray, 0)); //first row System.out.println("Total of row 2:" + Array Operations2D.getRow Total(darray, 1)); //second row System.out.println("Total of col 2:" + ArrayOperations2D.getColumn Total(darray, 1)); //second column System.out.println("Total of col 3 :" + Array Operations2D.getColumn Totaldarray, 2)); //third column System.out.println("Highest in row 1:" + Array Operations2D.getHighestInRow(darray, 0)); //first row System.out.println("Highest in row 2:" + Array Operations2D.getHighestInRow(darray, 1)); //second row System.out.println("Lowest in row 1:" + Array Operations2D.getLowestInRow(darray, 0)); //first row System.out.println("Lowest in row 2 :" +Array Operations2D.getLowestinRow(darray, 1)); //second row iab 3 Write a class called ArrayOperations2D. The class should have the following static methods: ..getTotal. This method should accept a two-dimensional array as its argument and return the total of all the values in the array. .getAverage. This method should accept a two-dimensional array as its argument and return the average of all the values in the array. getRowTotal. This method should accept a two-dimensional array as its first argu- ment and an integer as its second argument. The second argument should be the sub- script of a row in the array. The method should return the total of the values in the specified row. ! ! .getColumnTotal. This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a column in the array. The method should return the total of the values in the specified column. getHighest InRow. This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a row in the array. The method should return the highest value in the specified row of the array. . get Lowest InRow. This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a row in the array. The method should return the lowest value in the speci- fied row of the array. Write a demo program called ArrayOperatins2D Demo that creates a two-dimensional double array initialized with the testing data provided. Demonstrate each of the methods in ArrayOperations2D class
