Byte[] and java.lang.OutOfMemoryError reading file by bits

Question

I am trying to write a reader which reads files by bits but I have a problem with large files. I tried to read file with 100 mb and it took over 3 minutes but it worked.

Answer 1

You shouldn't open the whole file into memory. You need to create a byte array buffer with a fixed size, then you open your file from chunks of the size you defined.
