Mistakes i noted:
1. your union function is wrong. no items are ever added to result. an easy way to do it would be to have result contain the same contents of elements and then add items from s if...

masterhand,
ilan is correct. What you have written is for the while loop to run if at least one of them is under 100.
You want it to terminate when one goes over, so you check if both are under 100.

try:

int rand=(int)(Math.random()*ArrayListName.size());
System.out.println(ArrayListName.get(rand));

You just need a non-static final variable.

IB's void M doesn't really override IA's void M because IB's method restricts the arguments to only ID's so ID is different from IC. Therefore void M would be an overloaded method.

I have use multiple for loops, but i have had trouble getting it to print the middle line for example
I have been able to print(for ex.f) ffffff and ffffff eeeee dddd ccc bb a, but i cannot figure...

Use following code


Scanner keyb = new Scanner(in);
int a = keyb.nextInt();
int b = keyb.nextInt();
int c = keyb.nextInt();
double d = pow(b,2);
double f = sqrt(d-(4*a*c));
double g =...

You input a letter. Then you print it its place in the alphabet time(for example b would be bb).
Then you print it again and then add the letter before it, its corresponding position number of...

How do you print such problem?

Enter a letter
Ex. f

ffffff
ffffff eeeee
ffffff eeeee dddd
ffffff eeeee dddd ccc
ffffff eeeee dddd ccc bb
