Elsa { st.push(x); (st.isEmpty()) ends a and static void insertat_bottom(char x) call the function print the stack System.out.println(Original Stack); #push elements into the stack public static void main(String[] args) static Stack<Character> st = new Stack<>(); public class Test3 import java.util.Stack; When the stack becomes empty, the st size becomes 0. Java code to reverse a stack using recursion. All items are held in Function Call Stack until we reach the end of the stack. Below is a recursive function that inserts an element at the bottom of a stack insert_at_bottom to insert a character at the bottom of the stack.
