This program takes the number of years and iterations to be runned. It then calculates the scores and stores them in the 2 dimensional score array based on the number of iterations and years.

For example,if the program is runned five times(iterations=3 and years=2), this could be the output.


               Iterations 1   Iteratons 2   Iterations 3
Years   1  2.666667       2.66667         2.66667  
Years  2   3.2224           3.2221          3.4

so what i need to do is to find the percentage for the range based on years
For example, for year 1 , how many times got value between 2.6 to 2.7

For example, for year 2,how many times, got value between 3.2 to 3.3, 3.3 to 3.4

I just realized that the map below takes all the value in and does not consider it based on years..Is there a way to make the map think in years.

Map <Double,Integer> map=new HashMap<Double,Integer>();

for(int i=0;years+1;i++)
for(int j=0;j<iterations;j++){
Integer val=map.get(score[i][j]);

int newVal=val+1;

use 2 maps, one for year 1 and the other for year 2.
If there could be even more years then use a list of maps

I get error ambigious...

I hope, it is ok if put ArrayList in front instead of List..When i compile,it is ok...

ArrayList<Map <Double,Integer>> maps= new ArrayList<Map <Double,Integer>>(years+1);
