This week's book giveaway is in the Servlets forum. We're giving away four copies of Murach's Java Servlets and JSP and have Joel Murach on-line! See this thread for details.

Hey! can somebody help me doing this please? i will really appreciate it!

Write an application that reads the lengths of the sides of a triangle from the user. Compute the area of the triangle using Heron's formula (below), in which s represents half of the perimeter of the triangle, and a, b, and c represent the lengths of the three sides.

The philosophy of JavaRanch is that we help you to learn Java, but you don't learn Java if someone else would just do your homework for you. So, please show some effort - what have you tried yourself, and where do you get stuck.
