Question Please boys. Help? hh

Alright, basically I'm trying to get amount of online players having a Minecart in their inventories. I'm totally confused. Help would be soooo appreciated.

 

Here's some code that you can base making yours off of.

Code:

// Make variable that will count how many mine
int amount = 0

// This will iterate through each player that is online
for (Player p : onlineplayers) {

// This will iterate through each slot in the player's inventory
    for (int i = 0; i < 36; i++) {

// If the slot is null, skip it and proceed to the next one
        if (inv.getItem(i) == null)
            continue;
// If the slot material is equal to a minecart
        if (inv.getItem(i) == minecart) {

// Add 1 to the amount
            amount++

// By making i == 36, you will go to the next player
            i = 36;
        }
    }
}

This could SHOULD work. It's up to you to figure out the actual code to use though, I've provided the logic of what you need to do.
