Sum of all even numbers up to but not including 100

First off- Hello everyone!! I am new to this forum and Java Programming.

My Structure of Computer Programming instructor has been pretty redundant the first couple of lectures, and then out of no where gave us like 5 assignments, 2 of which are way beyond the scope of what we talked about in class. I did some research online and found some tutorials that list even numbers using the ParseInt method but Im still lost.

I have to write a Java program that sums all the even numbers up to but not including 100. For example, the sum of the even numbers up to but not including 10 is:

2+4+6+8 = 20
