Selection Sort in Java

Here is the implementation of selection sort using Java as my programming language. Our program will ask the user how many items to be sorted and then it will ask the user to give a series of numbers and then it will be sorted using selection sort algorithm. I hope you will find my work useful. 

I am currently accepting programming work kindly contact me in the following email address for further details. Thank you.
