Answer 1

I think you need use List or classes based on that.

For instance,

ArrayList integers = new ArrayList();
int j;

do{
    integers.add(int.nextInt());
    j++;
}while( (integers.get(j-1) >= 1) || (integers.get(j-1) <= 100) );

You could read this article for getting more information about how to use that.
