Java Vector:
The Vector class implements a growable array of objects. Like an array, it contains components that can be accessed using an integer index. However, the size of a Vector can grow or shrink as needed to accommodate adding and removing items after the Vector has been created.
Each vector tries to optimize storage management by maintaining a capacity and a capacityIncrement. The capacity is always at least as large as the vector size; it is usually larger because as components are added to the vector, the vector’s storage increases in chunks the size of capacityIncrement. An application can increase the capacity of a vector before inserting a large number of components; this reduces the amount of incremental reallocation.
Example
package com.candidjava.core;
import java.util.Vector;
public class VectorExample {
public static void main(String[] args) {
Vector<String> vt = new Vector<String>();
vt.add("hai");
vt.add("123");
vt.add("mathan");
vt.add("lvt");
vt.add("mathan");
vt.add("lvt");
vt.add("ramya");
vt.add("suji");
vt.add("ravathi");
vt.add("sri");
System.out.println("Vector .. " + vt);
System.out.println("size ... " + vt.size());
}
}Output:
Vector .. [hai, 123, mathan, lvt, mathan, lvt, ramya, suji, ravathi, sri] size ... 10
