Can I write the end of a 5GB file in Java? The question appeared in my office, and no one was sure what the answer was

Solution

This should be easily achieved using RandomAccessFile The following should be valid:

RandomAccessFile myFile = new RandomAccessFile(filename,"rw");

// Set write pointer to the end of the file
myFile.seek(myFile.length());

// Write to end of file here
