convert code into a method with header:
I just wrote a code to multiply two polynomials together but I dont know what it means to convert it into a method with a header, thanks..
public class MultPoly // tests multiplication of two polynomials
{
public static void main (
String[] args)
{
int[] p = {2, 5, 3, 4};
int m = p.length - 1; // degree of p
int[] q = {4, 6, 8};
int n = q.length - 1; // degree of q
int[] r = new int [m + n + 1];// This will store the product.
for (int i = 0; i < p.length; i++)
{ //increments leading coefficient
for (int x=0; x < q.length; x++)
{
r[i + x] += (p[i] * q[x]);
}
}//for
int k;
for (k = 0; k < r.length - 1; k++)
{
System.out.print (r[k] + ", ");
}
System.out.println (r[k] + "."); // prints out final digit of polynomial
}//main
}//class
