This puzzle is tripping me up for some reason. For instance, result = result + obs[x].doStuff(x); Why the need for doStuff(x)? Also, it doesn't give "factor" a value and it seems it should have one? Here is the code and the output for the puzzle:
public class Puzzle4 {
public static void main(String[] args) {
Puzzle4b[] obs = new Puzzle4b[6];
int y = 1;
int x = 0;
int result = 0;
while (x < 6) {
obs[x] = new Puzzle4b();
obs[x].ivar = y;
y = y * 10;
x = x + 1;
}
x = 6;
while ( x > 0 ) {
x = x - 1;
result = result + obs[x].doStuff(x);
}
System.out.println("result " + result);
}
}
class Puzzle4b {
int ivar;
public int doStuff(int factor) {
if (ivar > 100) {
return ivar * factor;
}else{
return ivar * ( 5 - factor );
}
}
}
Output:
%java Puzzle4
result 543345
