1. (a). Write a Java statement that declares and creates a 2D integer array called int_arr with 5 rows and 7 columns (b). Use a nest for loops to assign an integer value i*j (the product of row number i and column number j of array int_arr) to each array element of the 2D array int_arr (c). Change the value of the last array element in row 0 to 5 (d). Change the value of the very last array element of the 2D array int arr to 10. (e). Change the value of the very first array element of the 2D array int_arr to 10 (f). Write a Java for loop to print every array element in the first row. (g). Write a Java for loop to print every array element in the last column. Answer: 1. (a).
