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) {
Stack st = 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());
}
}
