Strange problem in java
Hi,
I have a following program , this program call aother classes .
my problem is that if I run loop to call the classe
for (int i =3;i<=4;i++), I get a strange error saying :
Classification accuracy = 100.0 %
error accuracy = 0.0 %
Accuracy = 100.0 %
Error rate = 0.0 %
java.io.FileNotFoundException: dataf\iris\TrainingData.txt (Access is denied)
But when I run for evry single iteration for example
for (int i =3;i<=3;i++),
There is no problem, I need 10 iteration for this code so, it is not cconvenient to everytime for every iteration I run the program again and chnage the loob for every single iteration to get correct results like this:
for (int i =1;i<=1;i++), :
run again
for (int i =2;i<=2;i++), :
run again
for (int i =3;i<=3;i++), :
........
until for (int i =10;i<=10;i++), :
This gives correct results but as I mentioned this is not good coding, is there anyway to avoid that I just run oncefor (int i =1;i<=10;i++), :
My code is attached under"

static double [] AccuracyCal = new double [10];
