Question

I want to set the fields of a given source date to a given target date using this method.

private static void setFields(final Date source, 
    final Date target, 
    final int ... fields)
{
    final Calendar sourceCalendar = Calendar.getInstance();
    sourceCalendar.setTime(source);

    final Calendar targetCalendar = Calendar.getInstance();
    targetCalendar.setTime(target);

    for(int field : fields)
        targetCalendar.set(field, sourceCalendar.get(field));
}

The minute of the target Date is not set.
How am I suppose to set it if I don’t want to break the reference by using.

target = targetCalendar.getTime();

Answer 1

To change the target date to the value in the targetCalendar, use:

target.setTime(targetCalendar.getTime().getTime());

Assuming that’s what you were asking, your question was a little unclear.
