programming language : java

See the attached for question. Use the double array given below and the skeleton of demo should look like the following.

public class ArrayOperations2DDemo

{

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 ",

ArrayOperations2D.getTotal(darray));

System.out.printf("Average : %.2f ",

ArrayOperations2D.getAverage(darray));

System.out.println("Total of row 1 : " + ArrayOperations2D.getRowTotal(darray, 0)); //first row

System.out.println("Total of row 2 : " + ArrayOperations2D.getRowTotal(darray, 1)); //second row

System.out.println("Total of col 2 : " + ArrayOperations2D.getColumnTotal(darray, 1)); //second column

System.out.println("Total of col 3 : " + ArrayOperations2D.getColumnTotal(darray, 2)); //third column

System.out.println("Highest in row 1 : " + ArrayOperations2D.getHighestInRow(darray, 0)); //first row

System.out.println("Highest in row 2 : " + ArrayOperations2D.getHighestInRow(darray, 1)); //second row

System.out.println("Lowest in row 1 : " +ArrayOperations2D.getLowestInRow(darray, 0)); //first row

System.out.println("Lowest in row 2 : " +ArrayOperations2D.getLowestInRow(darray, 1)); //second row

}

}

der DC Lab 3.pdf * starting-out-with-ja... Chapter2Notes.pdf Q 1.11. Am o 100% TI 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 ArrayOperations 2D class.
