java - How do I define an array with multiple values? -

i doing junit testing on code, meant produce arraylist of n prime numbers. want compare created list list of known prime numbers in array, , need insert multiple values array in testing class.

so have @ moment

int knownprimes[] = new int[50]; 

i know insert values array typing

knownprimes[1] = 2; knownprimes[2] = 3; etc etc. 

i wondering how in 1 big chunk, maybe like:

knownprimes[] = {2,3,5,7,9...}; 

but not sure of syntax , can't find on google. able me out please ?

thanks lot.

int[] knownprimes = new int[] {2, 3, 5, 7, 9}; 

as peter mentioned, new int[] can omitted.
