Reading huge textfiles Java

Question

I've got a .txt with 1 Billion digits of pi. I read in the file as a String but i get an OutOfMemoryError. It worked with 1 MIllion digits tho. I save the String as a char[] array. Is it possible to somehow stream the .txt when i cycle through the whole array? I simply need a way to have access to all the 1 Billion digits as an array.

Answer 1

There is BufferedInputStream since java 1 or FileReader with

public int read(char cbuf[], int offset, int length) throws IOException 

I suggest you start from there
