Need help understanding strange array syntax

Question

I found this bit in a book and I don\'t get what it does:

int index = 1;
...
getArray() [index=2]++;

[index=2]++; looks strange to me,

Answer 1

getArray() must return an array of numbers (let's say ints), so getArray() [index=2]++; dissected:

int index = 2;
int[] array = getArray();
array[index] = array[index] + 1;
