The method selectionModel.getSelectedIndices() returns an ObservableList<Integer> and not an array. So you have to use that List, or convert that list into an array.
To get the size of the List you can just use the list.size() method. To get an Element from the List you can use list.get(index). Here are the complete java docs for ObservableList.
public void calculateTotal()
int wheelIndex = wheels.getSelectionModel().getSelectedIndex();
int deckIndex = decks.getSelectionModel().getSelectedIndex();
int truckIndex = trucks.getSelectionModel().getSelectedIndex();
ObservableList<Integer> miscList = misc.getSelectionModel().getSelectedIndices();
int miscTotal = 0;
for(int i = 0; i < miscList.size(); i++)
miscTotal += miscPrices[miscList.get(i)];
Alternatively you could use Java Streams:
int miscTotal = miscList.stream().mapToInt(i -> miscPrices[i]).sum();
If you want to transform the ObervableList to an array (I would not do that) you can use the list.toArray() method.

The method selectionModel.getSelectedIndices() returns an ObservableList<Integer> and not an array. So you have to use that List, or convert that list into an array.

public void calculateTotal()
int wheelIndex = wheels.getSelectionModel().getSelectedIndex();

int truckIndex = trucks.getSelectionModel().getSelectedIndex();
ObservableList<Integer> miscList = misc.getSelectionModel().getSelectedIndices();
int miscTotal = 0;
for(int i = 0; i < miscList.size(); i++)
miscTotal += miscPrices[miscList.get(i)];
Alternatively you could use Java Streams:
int miscTotal = miscList.stream().mapToInt(i -> miscPrices[i]).sum();
If you want to transform the ObervableList to an array (I would not do that) you can use the list.toArray() method.
