Is there a function in java to get moving average

Question

I have a situation where I need to process 5000 samples from a device in every 0.5 sec.

Lets say the window size is 100, then there would be 50 points resulting fro

Answer 1

static int[] myIntArray = new int[16];
public static double maf(double number)
{
    double avgnumber=0;
    for(int i=0; i<15; i++)
    {
        myIntArray[i] = myIntArray[i+1];
    }
    myIntArray[15]= (int) number;
    /* Doing Average */
    for(int  i=0; i<16; i++)
    {
        avgnumber=avgnumber+ myIntArray[i];
    }
    return avgnumber/16;

}

this algorithm can also be called as Moving Average Filter which is working well for me ... i implemented this algo in my graph project!
