Get ArrayList Length

To get the length of the array list, we use the size() method. For example,


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

Output


\begin{lstlisting} ArrayList: [Dog, Horse, Cat] Size: 3 \end{lstlisting}
