Question

Consider the following definitions

int[ ][ ] numbers = {{1, 2, 3},

                                {4, 5, 6} };

The following code below produces

for (int row = numbers.length - 1; row >= 0; row -- )

{

for (int col = 0; col < numbers[0].length; col ++)

{

System.out.print (numbers [row][col]);

}

}

Answer 1

The code produces the output of 456123

Initially we start row from 1 and col runs from 0 to 2.

which prints numbers[1][0] numbers[1][1] numbers[1][2] which are 456 respectively

then row becomes 0 and col runs from 0 to 2 printing

numbers[0][0] numbers[0][1] numbers[0][2] which are 123 respectively

thus output is 456123

Note no space or new line is added as system.out.print has been used
