Q5. Given the code fragment:
int [][] array2d = new int[2][3];
System.out.println("Loading the data.");
for ( int x = 0; x < array2d.length; x++) {
for ( int y = 0; y < array2d[0].length; y++) {
System.out.println(" x = " + x);
System.out.println(" y = " + y);
// insert load statement here.
}
}
System.out.println("Modify the data. ");
for ( int x = 0; x < array2d.length; x++) {
for ( int y = 0; y < array2d[0].length; y++) {
System.out.println(" x = " + x);
System.out.println(" y = " + y);
// insert modify statement here.
}
}
Which pair of load and modify statement should be inserted in the code? The load
statement should set the array's x row and y column value to the sum of x and y
The modify statement should modify the array's x row and y column value by multiplying it by 2
A. Load statement: array2d(x,y) = x + y;
Modify statement: array2d(x,y) = array2d(x,y) * 2
B. Load statement: array2d[x y] = x + y;
Modify statement: array2d[x y] = array2d[x y] * 2
C. Load statement: array2d[x,y] = x + y;
Modify statement: array2d[x,y] = array2d[x,y] * 2
Oracle 1z0-803 : Practice Test
D. Load statement: array2d[x][y] = x + y;
Modify statement: array2d[x][y] = array2d[x][y] * 2
E. Load statement: array2d[[x][y]] = x + y;
Modify statement: array2d[[x][y]] = array2d[[x][y]] * 2
