Stack Class In Java

#BackCoding

The stack is a linear data structure that is used to store the collection of objects. It is based on Last-In-First-Out (LIFO). Java collection framework provides many interfaces and classes to store the collection of objects. One of them is the Stack class that provides different operations such as push, pop, search, etc.

import java.util.*;

class StackDemo{

public static void main (String args[]){

Stack<Integer> st=new Stack<>();

int choice=0;
int position, element;

Scanner scr=new Scanner(System.in);

while(true){

System.out.println("Menu");

System.out.println("1..Push an Element");
System.out.println("2..Pop an Element ");
System.out.println("3.. Search an Element");
System.out.println("4.. Exit");

System.out.print("Enter your choice:-");
choice=scr.nextInt();

switch(choice){
case 1:
System.out.print("Enter element :");
element=scr.nextInt();
st.push(element);
break;

case 2:
Integer obj=st.pop();
System.out.println("Popped ="+obj);
break;

case 3:
System.out.println("which element? :");
element=scr.nextInt();
position=st.search(element);
if(position==-1){
System.out.println("Element not found");
}else{
System.out.println("Position :"+position);
}
break;

case 4:
System.exit(0);

default:
return;
}
System.out.println("Stack Contents "+st);
}
}
}

It's recommended to use the Deque collection instead of the Stack

You have to type this much in java lol, In python we can finish it with less than 10 lines
