Sum and Count using array, vector???

[meracle]

here's my condition:

int count =0;

if (percent >100){
count = 1;
value = 50;
}
else if (percent >=90 || percent <100){
count = 1;
value = 40;
}
.
.
.


I want to get the counter in the particular ramge of percentage and sum the value up...for example if i get the counter of 4 in the percentage range > 100, the result will return the count = 4, the sum value =(4*50) = 200.
The question is, how to store the value and sum up of them as well as to get the counter?? Becoz the data will loop inthe database...Using vector, or linklest, or array???
Who can show some sample codes for me??

// you should tell us more details about your problem
// check the following code if this suits you
class sum
{
public static void main(String args[])
{
final int VALUE50 = 0;
final int VALUE40 = 1;
final int VALUE30 = 2;
final int VALUE20 = 3;
final int VALUE10 = 4;
int dataFromDb[] = new int[1000];
int count[] = new int [5], sum[] = new int [5];

// select percent from myTable into dataFromDb
int dataCount = 6;
dataFromDb[0] = 101;
dataFromDb[1] = 92;
dataFromDb[2] = 83;
dataFromDb[3] = 70;
dataFromDb[4] = 60;
dataFromDb[5] = 55;
for (int i=0; i<dataCount; i++)
{
if (dataFromDb>=100)
{
count[VALUE50]++;
sum[VALUE50]+= 50*dataFromDb;
}
else if (dataFromDb>=90 && dataFromDb<100)
{
count[VALUE40]++;
sum[VALUE40]+= 40*dataFromDb;
}
else if (dataFromDb>=80 && dataFromDb<90)
{
count[VALUE30]++;
sum[VALUE30]+= 30*dataFromDb;
}
else if (dataFromDb>=70 && dataFromDb<80)
{
count[VALUE20]++;
sum[VALUE20]+= 20*dataFromDb;
}
else if (dataFromDb>=60 && dataFromDb<70)
{
count[VALUE10]++;
sum[VALUE10]+= 10*dataFromDb;
}
}
for (int i=0; i<sum.length; i++)
{
System.out.println(&quot;Sum&quot;+i+&quot; =&quot;+sum+&quot;, &quot;+&quot;count&quot;+i+&quot; =&quot;+count);
}
}
