Question

I’m looking for a way to read a large number of ints from a DataInputStream and load them into an array. I know exactly how many ints I need to read, but it’d be nice if there was a cleaner way than to simply iterate.

There is already a way to do this with a byte array, just by using the DataInputStream#read(byte[]) method, but there is no equivalent for int[]. I could obviously read the data into a byte array by creating a byte array with the length multiplied by four, but I really need the data in ints.

The way I see it, there are three possibilities I could use:

1. Somehow load the data directly into an int[].
2. Somehow convert a byte[] into an int[].
3. Iterate through the array and just use readInt().

While the first two solutions are much preferred, I currently don’t know of a way to do either. Is there any simple way to do this without iteration?

Answer 1

It would appear that the only way to do this is a simple for loop and using readInt(). This is what I eventually opted to do.
