Example of Stack in Java
June 09, 2013
java.util.Stack behaves as Stack i.e. first in last out. push() and pop() methods are there in Stack. push() method pushes the element at the top of element. pop() method removes the element from the top. Find the example.
StackDemo.java
package com.concretepage.util; import java.util.Stack; public class StackDemo { public static void main(String[] args) { Stackst = new Stack (); st.add("A"); st.add("B"); st.add("C"); for(String s : st){ System.out.println(s); } //returns current capacity of Stack System.out.println(st.capacity()); //returns true if empty System.out.println(st.empty()); //returns first element System.out.println(st.firstElement()); //returns last element System.out.println(st.lastElement()); //gets the top element but does not remove System.out.println(st.peek()); //pushes the element at the top of element System.out.println(st.push("D")); //removes the element from the top System.out.println(st.pop()); } }
