Java Array help!?

Question

ok im taking a number in as user input and i want the array to be that long. My problem is this. Ok say i get 20 as the input. I want the array to be from 1-20 not 0-20. how do i do that. The way i have it now is this.
boolean answer[] = new boolean[number]; ( number being my input)

I know what i have is right but i dont want it to be from 0-19. It has to be from 1-20 or it will not work.

Answer 1

Then add 1 to the number input to create the array.
You now have an array of length 21 but with elements 1-20 as you require. You will just not be using element 0.

Answer 2

What you have is right. The array indicies will be 0-19 in your example.

Answer 3

boolean answer[] = new boolean[number+1];

basically you leave the first array cell blank, if you don't need it. programming languages normally start indexes with zero.

Answer 4

write a function like this and use it to get values from array

int get(i)nt pos)
{
return array[pos-1];
}
