Have you attempted to work this out on your own? Are you stuck on a particular concept or do you have no idea where to start?

The thing is, we're not here to do your homework. I suggest you do the following:

1. Read your textbook and try to create a very simple Java program. There may even be a simple "Hello World" program for you to try.

2. In that program, you will probably have a main() method. You can add your own code to that main() method. That's where you can add your statements.

3. For Question 1, you can use a*for*loop to iterate through all of the numbers from 1-20. To determine if a number is even, use the*modulus*(%) operator. For example 8 % 2 will return 0. That means 8 is an even number.

4. Once you have determined that a number is even, add it to your running total.

5. When the for loop ends, display your running total.

After you get through Question 1, you will be better prepared to tackle Question 2.

Lets not spoonfeed him such simple code.

@op: we try not to give you code, you won't learn that way.

This is pretty easy(and logical)

Just google how loops work and then think how you would do this by hand and you can easily figure it out.
