Solved Not detecting block

Im trying to see if the player is looking at a chest, if so do something, this is what ive tried so far:

Code:

Block look = p.getTargetBlock((Set<Material>)null, 1);
if(look instanceof Chest)
{
        //Do something
}

Code:

Block look = p.getEyeLocation().getBlock();
if(look instanceof Chest)
{
        //Do something
}

Code:

Material look = p.getEyeLocation().getBlock().getType();
if(look == Material.CHEST || look.equals(Material.CHEST))
{
        //Do something
}

and its not working, if anyone can help that'd be great, thanks.

The first option was sort of correct; The 1 should have been replaced with a 6 (since that is the maximum distance bukkit will check for).

I changed it to this now and still isn't working

Block look = p.getTargetBlock((Set<Material>)null, 6);

Edit: It does work but now i have a new problem, how to I change the block to be a chest, i tried to do

Chest c = (Chest) look;
and it gives me this error:

27.08 16:15:13 [Server] INFO Caused by: java.lang.ClassCastException: org.bukkit.craftbukkit.v1_11_R1.block.CraftBlock cannot be cast to org.bukkit.block.Chest

Edit: I fixed it, i forgot to do look.getState(); :/
