Question

Write a Java code to implement the concept of vector and stack.
Generate the correct output.

Answer 1

To implement the concept of vector and stack in Java, you can use the Vector and Stack classes provided in the Java Collections framework. This allows you to store and manipulate data in a way that follows the principles of vectors and stacks. You can create a Vector object and add elements to it, and then access those elements using the get() method. Similarly, you can create a Stack object and push elements onto the stack using the push() method, and then pop elements off the stack using the pop() method.

Step-by-step explanation:

To implement the concept of vector and stack in Java, you can use the Vector and Stack classes provided in the Java Collections framework. Here's an example:

import java.util.Vector;
import java.util.Stack;

public class VectorStackExample {

public static void main(String[] args) {
// Creating a vector
Vector<String> vector = new Vector<>();

// Adding elements to the vector
vector.add("Element 1");
vector.add("Element 2");
vector.add("Element 3");

// Accessing elements from the vector
System.out.println(vector.get(0)); // Output: Element 1
System.out.println(vector.get(1)); // Output: Element 2
System.out.println(vector.get(2)); // Output: Element 3

// Creating a stack
Stack<String> stack = new Stack<>();

// Pushing elements to the stack
stack.push("Element 1");
stack.push("Element 2");
stack.push("Element 3");

// Accessing elements from the stack
System.out.println(stack.pop()); // Output: Element 3
System.out.println(stack.pop()); // Output: Element 2
System.out.println(stack.pop()); // Output: Element 1
}
