The expression whose value is that of the first element in the first row is array[0][0].
It's a grid, like in the game battleship, so the bottom left would be A1 and so on if the grid looked like this:
_ 1 2 3 4 5
D
C
B
A
But instead of letters and numbers, in java its numbers and numbers so the grid looks like this (for 3 x 3)
_0 1 2
0
1
2
so the first element of the first row would be expressed as (assuming the array was called an array)
array[0][0]
the second item in the last row would be
array[2][1]
Hence the expression whose value is that of the first element in the first row is array[0][0].
