Java – How to subtract two XmlGregorianCalendar objects to create one Duration object

java

I want to compute the delta of time, a subtraction, between two XmlGregorianCalendar objects, so as to create a Duration object.

But I haven't found clean ways of performing that subtraction. How would you do it?

Best Answer

That should be:

DatatypeFactory.newDuration(xgc2.toGregorianCalendar().getTimeInMillis() - xgc1.toGregorianCalendar().getTimeInMillis())

I found a one-line solution from the good old Apache Commons Lang library.
ArrayUtils.addAll(T[], T...)

Code:

String[] both = ArrayUtils.addAll(first, second);

Yes, it is possible:

public class Foo {
    private int x;

    public Foo() {
        this(1);
    }

    public Foo(int x) {
        this.x = x;
    }
}

To chain to a particular superclass constructor instead of one in the same class, use super instead of this. Note that you can only chain to one constructor, and it has to be the first statement in your constructor body.

See also this related question, which is about C# but where the same principles apply.
