implementing stack java code example

Example 1: java stack methods

import java.util.Stack<E>;
Stack<Integer> myStack = new Stack<Integer>();
myStack.push(1);
myStack.pop();
myStack.peek();
myStack.empty(); // True if stack is empty

Example 2: stack in java

// Java code for stack implementation 

import java.io.*; 
import java.util.*; 

class Test 
{ 
	// Pushing element on the top of the stack 
	static void stack_push(Stack<Integer> stack) 
	{ 
		for(int i = 0; i < 5; i++) 
		{ 
			stack.push(i); 
		} 
	} 
	
	// Popping element from the top of the stack 
	static void stack_pop(Stack<Integer> stack) 
	{ 
		System.out.println("Pop Operation:"); 

		for(int i = 0; i < 5; i++) 
		{ 
			Integer y = (Integer) stack.pop(); 
			System.out.println(y); 
		} 
	} 

	// Displaying element on the top of the stack 
	static void stack_peek(Stack<Integer> stack) 
	{ 
		Integer element = (Integer) stack.peek(); 
		System.out.println("Element on stack top: " + element); 
	} 
	
	// Searching element in the stack 
	static void stack_search(Stack<Integer> stack, int element) 
	{ 
		Integer pos = (Integer) stack.search(element); 

		if(pos == -1) 
			System.out.println("Element not found"); 
		else
			System.out.println("Element is found at position: " + pos); 
	} 


	public static void main (String[] args) 
	{ 
		Stack<Integer> stack = new Stack<Integer>(); 

		stack_push(stack); 
		stack_pop(stack); 
		stack_push(stack); 
		stack_peek(stack); 
		stack_search(stack, 2); 
		stack_search(stack, 6); 
	} 
}

Example 3: stack class in java

import java.util.Stack;
class Main {
    public static void main(String[] args) {
        Stack<String> animals= new Stack<>();
        // Add elements to Stack
        animals.push("Dog");
        animals.push("Horse");
        // Remove element from Stack
      	animals.pop();
      	// Access element from top of Stack
      	animals.peek();
    }
}
