I have a weird scenario where I need to convert several million java.lang.Longs into primitive int types. I need to do this several times a day, every single day. Normally, I wouldn’t worry about this kind of simple casting, but since it’s happening so much, so often, I have to ask: what’s the most efficient way to do this, and why?
My first attempt:
Long myLong = getLong();
int x = Integer.valueOf(myLong.toString())
Although this seems like going 3 sides around the barn. Thanks in advance.
The
Longclass has an.intValue()method, I guess this is what you are looking for…(warning, you may lose precision etc etc — but you probably know that already)
