Solved Skipping Iterations in BukkitRunnables?

Hi yall, I've got a BukkitRunnable that has a number and I want it to act like a for loop in some ways. So right now I have it with an int that increased each time it runs, and that int is the index for a list like this:

Code:

int x = 0;
public void run(){
//blocklist is a ArrayList that has blocks
Block block = blocklist.get(x);
}

but I'm testing if the block is TNT, and if it is, I just want to move onto the next block so I have this:

Code:

if(block.getType() == Material.tnt) ...

I don't know where to go from here. Ive tried just doing return; but it just cancels the runnable. I do have a null checker with the block to make sure its not null, too, and I want to do the same with that. So I just want to skip the rest of the code in the loop to make sure I don't have the tnt or null blocks
thanks!

edit I have realised a mistake I made so I don't need help
