Hey guys, can anyone quickly tell me how i would do this thanks

well i have got all my Projectile done well most but i rushed them and coded them shit.

can anyone please tell me how i would change it into an array like this

Code:
private static final int[][] arrows = new int[][]{{385, 20}};
Thanks

Edit: this is what i got at the moment

Code:
    public void rangeProjectile2(Player p, NPC p2) {
        int offsetX = (p.absX - p2.absX) * -1;
        int offsetY = (p.absY - p2.absY) * -1;
	p.frames.createGlobalProjectile(p.absY, p.absX, offsetY,
	    offsetX, arrow(p.equipment[13]), 53, 31, 95, p2.npcId);
    }

    public int arrow(int id) {
        if (id == 882) {
            return 10;
        }
		if (id == 9236 || id == 9244) {
            return 27;
        }
        if (id == 884) {
            return 11;
        }
        if (id == 886) {
            return 12;
        }
        if (id == 888) {
            return 13;
        }
        if (id == 890) {
            return 14;
        }
		if (id == 11212) {
            return 1120;
        }
        if (id == 892) {
            return 15;
        }
        return 15;
    }
Thanks again.
