Examples of java.util.List.indexOf()

java.util.List.indexOf()
Returns the index of the first occurrence of the specified element in this list, or -1 if this list does not contain the element. More formally, returns the lowest index i such that (o==null ? get(i)==null : o.equals(get(i))), or -1 if there is no such index. @param o element to search for @return the index of the first occurrence of the specified element inthis list, or -1 if this list does not contain the element @throws ClassCastException if the type of the specified elementis incompatible with this list (optional) @throws NullPointerException if the specified element is null and thislist does not permit null elements (optional)
