Java Program to Implement Sorted Vector

This is a Java Program to Implement Sorted Vector. Here Sorted vector is implemented using a vector and each inserted element is placed at correct position in the vector by insertion sort.

Here is the source code of the Java Program to Implement Sorted Vector. The Java program is successfully compiled and run on a Windows system. The program output is also shown below.
