How to replicate Ruby´s binary file reading with Java?
Hello to all guys,
Maybe some expert could help me.
I have a working ruby script shown below that reads a big binary file (more than 2GB). The chunks of data I want to analyze
is separated by the sequence FF47 withing the binary. So, in the ruby script is defined as "line separator" = FF47 ($/="\xff\x47")
in order to read the file "line by line" avoiding to load the entire big file in memory.
The program works great and now I'm trying to apply this algorithm in Java. I've seen built-in ways in java to read not big binary files
but I don't know how to set as line separator the sequence FF47.
I'm having trouble with reading information back into a program from a binary file. when i try to display the contents of the file i get a Memory fault(coredump). would anyone be able to assist?
this is my fread line fread(&file_data,sizeof(struct book_type),1,fileSave); ive also tried it without... (3 Replies)

The data (arrays from various stages of radar processing) comes in various formats, but mainly... (3 Replies)
