- 2DArray method:It will allocate a block of memory which represents a two-dimension arraybased on the input values supplied by the user. Ask the user to enter the number of rows andcolumn for 2D array that the user want to manipulate. The number of rows and columns that theuser enters may or may not define a square matrix (when the number of rows equals the numberof columns). The array will have exactly rows time columns (m * n) elements. It will notcontain any extra or empty cells. Initialize the “matrix” by rows with random number between 1to 100. Pass two arguments by out reference so that you can assign the number of row andcolumns of data to the first and second arguments. This is return 2D array method afterallocating new memory for 2D array and initialize it with random value.

PC #16. 2D Array Operations with Additional Requirements Write a program that creates an ArrayList of ArrayList of Doubles. The program should ask the user to enter the filename from the keyboard and validate the file for existence. Once the file is verified, the program should load the two-dimensional ArrayList with test data from the file. Be careful, as some of the files will contain rows with different number of elements. The program should work regardless whether the input data is perfectly rectangular or ragged. The program should have the following methods: • main. Main entry point for the program. • getRowSubtotal. This method should accept a two-dimensional ArrayList as its first argument and an integer as its second argument. The second argument should be the index of the row in the ArrayList. The method should return the subtotal of the values in the specified row. • getColSubtotal.
