The above code segment

Required

Which code displays "Cat"

First, we need to identify the location of C, a and t in the array

$C \to keyboard[2][2]$ i.e. C is at the 2nd row index and 2nd column index

$a \to keyboard[1][0]$ i.e. a is at the 1st row index and 0 column index

$t \to keyboard[0][4]$ i.e. t is at the 0 row index and 4th column index

Next convert C to lowercase.

This is done using: toLowerCase() method.

So, we have: keyboard[2][2].toLowerCase()

Next, we concatenate each of the above.

i.e. keyboard[2][2].toLowerCase()+keyboard[1][0]+keyboard[0][4]

Lastly, the statement is printed:

System.out.println(keyboard[2][2].toLowerCase()+keyboard[1][0]+keyboard[0][4]);
