public Class ComputePrimeSum
{
int sum = 0;
public void main (String [] args)
{
for (int i = 2; i <= 20; i++) // RULE OUT 1 AS WE ALREADY KNOW IT'S CASE
{
for (int c = 2; c <= i; c++)
{
if (((int) i/c == i/c) && (c < i)) // IF DIVISIBLE BY A NUMBER LOWER THAN IT
{
c = -1; // EXIT THE SECOND FOR LOOP
}
else if (((int) i/c == i/c) && (c == i)) // DIVISIBLE ONLY BY ITSELF
{
sum += i; //ADD TO THE VALUE OF SUM
}
}
}
System.out.printl // PRINT RESULT
}
}
I haven't tested it, so it may not work. I will test later, but the logic makes a lot of sense to me.

This stupid thing won't let me edit my answer!!! Arrghhhhhhhh
Anyway, the last bit is:
System.out.println(sum)
Anyway, the last bit is:
System.out.println(sum)
I don't know how this works.
