Vector in java

In the previous post, we have seen how to replace element with a new value in LinkedList. In this post, we will see about vector in java.

Vector has the following features.

• It implements List interface.
• Vector is synchronized. That’s why it is slow because in multiple-thread environment , it will hold the other threads in runnable or non-runnable state until current thread releases the lock of the object.
• Vector is a legacy class.
• Similar to array , elements of vector can be accessed using an integer index.
• Vector increments 100% means doubles the array size if total number  of elements exceeds than its capacity.
• Vector can use Enumeration interface as well as Iterator interface.

Let’s understand Vector with examples.

• Add an element to Vector
• Add Element at a Specified index in vector
• Remove Element from Vector
• Remove Element at a specified index from Vector
• Get SubList From Vector
• Sort a Vector using Collections.sort()
• Iterate Over a Vector using Enumeration
