Too many loops?

Apr 9 '12, 02:47 PM

Hello All!
I would greatly appriciate some help given I'm just starting out in Java. I have written a pice of code which includes a lot of "for" statments (a few of them are called below). Since they are essentially doing the same thing, (Adding the last X elements of different arrays to a different variable) would it be possible to simplfy this into a process that keeps getting called instead of writting a new for loop everytime i want to do this?

Code:

for (int n = 1; n < 100; n++) { Variable1 += Array1.get(Array1.size() - n); for (int j = 1; j < 40; j++) { Variable2 += Array2.get(Array2.size() - j); for (int l = 1; l < 93; l++) { Variable3 += Array3.get(Array3.size() - l);

Thank you in advance for anyone that can help out with this

You can try with a function like:

Code:

public int addLast(int amount, List array, int initialValue) {
    for (int i = 1; i <= amount; ++i) {
         initialValue += array.get(array.size() - i);
    }
    return initialValue;
}

usage:

Code:

   Variable1 = addLast(100, Array1, Variable1);
   Variable2 = addLast(40, Array2, Variable2);
   Variable3 = addLast(93, Array3, Variable3);
