Compound Interest in Java

 A Java program that I wrote to ask the user to give the principal amount, rate, and years to be paid by the user.

I am currently accepting programming work, IT projects, school and application development, programming projects, thesis and capstone projects, IT consulting work, computer tutorials, and web development work kindly contact me in the following email address for further details.  If you want to advertise on my website kindly contact me also in my email address also. Thank you.
