Servlets - Githubissues

zhamri commented 6 years ago

Write a Java Servlets to sum 10 random numbers between 100 and 200. Then list all the numbers and the result.

Example of output: Random numbers: 105, 150, 199, 133, 171, 175, 101, 188, 111, 136 Total: 1469

To answer this issue, you need to follow the guideline below:

Paste the servlets source codes here.
Attach the screenshot of the result here
Paste the link of the servlets here
Paste your references here
