Introduction

Java is a versatile programming language, widely used in the field of software development. As MSBTE Diploma students studying diploma engineering, you'll encounter various data structures during your coursework. One essential data structure is a vector, which is similar to an array but can dynamically resize itself. In this article, we will explore how to implement vectors in Java.

Vector Implementation in Java

In Java, you can use the Vector class from the java.util package to work with vectors. Here's a step-by-step guide to creating and using vectors:

Step 1: Import the necessary packages

import java.util.Vector;
import java.util.Iterator;

Step 2: Create a Vector

Vector<Integer> vector = new Vector<>();

Step 3: Add Elements to the Vector

vector.add(10);
vector.add(20);
vector.add(30);

Step 4: Access Elements

int element = vector.get(1); // Accessing the second element (index 1)

Step 5: Iterate through the Vector

Iterator<Integer> iterator = vector.iterator();
while (iterator.hasNext()) {
    int value = iterator.next();
    // Process the value
}

Code and Output

Let's see a complete Java program that implements a vector and prints its elements:

import java.util.Vector;
import java.util.Iterator;

public class VectorExample {
    public static void main(String[] args) {
        Vector<Integer> vector = new Vector<>();
        vector.add(10);
        vector.add(20);
        vector.add(30);

        System.out.println("Vector Elements:");
        Iterator<Integer> iterator = vector.iterator();
        while (iterator.hasNext()) {
            int value = iterator.next();
            System.out.println(value);
        }
    }
}

When you run this program, you'll get the following output:

Vector Elements:
10
20
30

Conclusion

Implementing vectors in Java is a fundamental skill for diploma engineering students. Vectors provide dynamic sizing, making them valuable for various applications. In this article, we've covered the basics of creating and using vectors in Java. You can explore further and use vectors in your projects to manage and manipulate data efficiently.
