In the code snippet above, we created anIntegerarray namedarray1, which contains a sequence of numbers. To find the index of a specific element (in this case,8), we first converted thearray1into anArrayListusingArrays.asList(array1). This conversion is necessary because theindexOf()method ...
public virtual int IndexOf(object? value, int startIndex); Parameters value Object The Object to locate in the ArrayList. The value can be null. startIndex Int32 The zero-based starting index of the search. 0 (zero) is valid in an empty list. Returns Int32 The zero-based index of...
Returns an index for which#valueAtwould return the specified key, or a negative number if no keys map to the specified value. Beware that this is a linear search, unlike lookups by key, and that multiple keys can map to the same value and this will fin...
