empty() Method

To check whether a stack is empty or not, we use the empty() method. For example,


\begin{lstlisting} import java.util.Stack; \par class Main { public static void... ...); System.out.println(''Is the stack empty? '' + result); } } \end{lstlisting}

Output


\begin{lstlisting} Stack: [Dog, Horse, Cat] Is the stack empty? false \end{lstlisting}
