Hello bluekswing.

Why don't you just create a class that can compare two Double numbers. For example:

Code:

public class NumberCompare{
    public enum TOperation {equals, greater, smaller, greaterOrEqual, smallerOrEqual};
    private TOperation operation = TOperation.equals;
    public void setOperation(TOperation operation){
        this.operation = operation;
    }
    public TOperation getOperation(){
        return this.operation;
    }
    public boolean compare(Double first, Double second){
        switch (operation){
            case equals :
                return first == second;
                break;
            case greater:
                return first > second;
                break;
            case smaller:
                return first < second;
                break;
            case greaterOrEqual:
                return first >= second;
                break;
            case smallerOrEqual:
                return first <= second;
                break;
            default:
                return false;
        }
    }
}

Now you can create a single NumberCompare object and change its operator as you need. Then you can call its compare() method. You can create a similar class for preforming the calculations. You can do the same for String objects.

This code has been checked by hand. I hope this helped.
