Answer 2

I started to write a code snippet for you, but realized you have a few too many undefined bits to your question.

1) Does the array need to store the integers 1-20 or the multiples of 5? This either makes it an array of 20 elements or an array of 4 elements.

2) Are you including the integer 20 in that computation?

3) What do you need to happen when a multiple of 5 is found? Display the value, put it in an array, increment a counter?

I'll take some liberties here...First obtain or create the array. If it's an array of 20 elements:

                              int[] numberArray = new int[20];

Now fill up your array if you have to:

              for (int i = 0; i < numberArray.length; i++){

                     numberArray[i] = i + 1;

              }

Here's where I don't know what you need to do with the multiples. You can use the same type of loop as above to do a few different things. You can use a switch statement (some logic that says "if the number in question is 5, 10, 15, or 20, do this action. Otherwise, do that action") to increment a counter, display the value, or put the value into another array, among many other things you could do when you find a value that fits the criteria.

I would be glad to elaborate on a more appropriate solution if you provide all the details of what you are trying to do, exactly.
