I want to write an average method in java such that it can consume N amount of items, returning the average of them:
My idea was:
public static int average(int[] args){
int total = 0;
for(int i=0;i<args.length;i++){
total = total + args[i];
}
return Math.round (total/args.length);
}
//test it
average(1,2,3) // s**hould return 2.
how can I change my method to consume any amount of parameters instead of int[] args so can work the way I want ? Cheers
Java 5 supports varargs, which is what you want.
e.g.
public static int average(Integer... ints) {
for (Integer i : ints) {
// sum here...
}
}
Since Java 5, there is a feature commonly called varargs which achieves what is desired.
Here's a little example:
public static int add(int... nums) {
int total = 0;
for (int n : nums)
total += n;
return total;
}
public static void main(String[] s) {
// The following prints "10"
System.out.println(add(1, 2, 3, 4));
}
