Simple Java Overriding Methods -

i wondering if possible override java methods in simpler way. basic problem have collection of methods, example can calculating mean of array of values. problem want have method work number variables types (int long double float etc.) there way besides creating:

1. a new method each parameter type
2. having new methods call 1 base method parsed parameters

any appreciated.

when reviewing answer, noticed have been using generics, didn't know called. here example of mean snippet.

   public double arithmeticmean(list<double> data) {          double sum = 0;         (double number : data)             sum += number;         return sum / data.size();     } 

i wondering if there anyway generalize other number variables (besides forms listed above.)

have investigated using generics , define new calculator object double, float, integer etc. ?
