quick q&a

[aizen92]

I recently knew that instead of writing

int n = 0;

i can write

int n;

well what about arrays
can i write

int [] array;

instead of

int [] array = new [n];

also, if yes, how can i use the array "array" later?
i want to assign to it later n elements

Yep, you can do that: you just define 'array' to be an array of ints but you don't initialize it, so:

int[] array; // defined but not initialized;
int[] array= new int[3]; // defined and initialized to three zero elements
int[] array= { 1, 2, 3 }; // defined and initialized to elements 1, 2 and 3

If you don't initialize your array you have to assign an array to it later if you want to use it:

array= new int[3]; // assign a new array of three zero elements
array= new int[] { 1, 2, 3 }; // assign an array with elements 1, 2 and 3

kind regards,
