Using removeAll() method

To remove all elements from an array list, we use the removeAll() method. For example,


\begin{lstlisting} import java.util.ArrayList; \par class Main { public static ... ...ls); System.out.println(''Final ArrayList: '' + animals); } } \end{lstlisting}

Output


\begin{lstlisting} Initial ArrayList: [Dog, Cat, Horse] Final ArrayList: [] \end{lstlisting}
