Creating a GridView based on user input using a for loop

I am trying to create a GridView that is based on the user input.
If the users input is x then the GridView shall show x elements. The problem is I don't want to have elements in GridView that starts with 0, as an Array in Java starts with index 0.
Here is a code snippet:
int numberOfTables=10; //let's say this is user input
String gridViewStrings = new String[numberOfTables];
for(int i =0; i<numberOfTables; i++){
gridViewStrings[i]="Table " +i;
The table descriptions should not start with 0, it should start with 1.
I tried to increment the array size by +1 but I get a BoundofException.
When you compile the code the output is :
Table0, Table1, Table2,...,Table9
The output I want is :
Table 1, Table2,...,Table10
How can I handle this ?

for(int i =1;i<numberOfTables; i++){ }
Try making your i to be 1. This might make the loop start at one not zero. and you moght not get an error
or you can try i+1
