What is the difference between these 2 lines of code?

boolean exists = groceryList.contains(searchItem);


int position = groceryList.indexOf(searchItem);






^groceryList is a class... using an arrayList:
private ArrayList<String> groceryList = new ArrayList<String>();

1st one returns true or false if searchItem is contained in the array or not

2nd one returns the location (index) of searchItem in the array
