Java Vector addAll() Method

Java Vector

In Java programming, Vector is a dynamic array that can grow and shrink automatically as needed. The Vector class provides many methods to manipulate its elements, among which the addAll(Collection c) method is a very practical method used to add all elements from a collection to the Vector.

---

Method Definition

The addAll(Collection c) method is defined as follows:

public boolean addAll(Collection<? extends E> c)

• Parameter: c is a collection containing the elements to be added to the Vector.
• Return Value: Returns true if the Vector changed as a result of this call; otherwise returns false.

---

Method Functionality

The addAll(Collection c) method adds all elements from the specified collection c to the end of the Vector. If collection c is empty, the Vector will not change.

---

Example

Here is a simple example demonstrating how to use the addAll(Collection c) method:

Example

import java.util.Vector;
import java.util.ArrayList;
import java.util.Collection;

public class VectorAddAllExample {
    public static void m
