Binarysearch in Java int[]

[!lkay]

Hallo.

	public static void sh(String t) {System.out.println(t);}
	public static void test()
	{
		sh("Digit 304, binary, Position(sorted): " + String.valueOf(binarys(new int[] {173,298,7893,304,101,99,83,43,98726,342, 654} , 304)));
	}

public static int binarys(int[] zahlen, int zahl){return Arrays.binarySearch(zahlen , 0 , zahlen.length - 1, zahl);}

Die Ausgabe ist immer -9. Was läuft da schief?

Arrays (Java Platform SE 6)

The array must be sorted (as by the sort(byte[]) method) prior to making this call. If it is not sorted, the results are undefined.
