RandomAccessFile：循环写入（字节）或写入（字节数组），哪个更有效？

Question

I am wondring what is more efficient should I use a for loop that invokes write with each byte x times, or I should have an array that will contain my data and write it with write(byte array)? Basically the question is write(byte array) more efficient than subsquent calls for write(byte) in a loop. I am programing in java and using RandomAccessFile.

Answer 1

Writing a byte array is always going to be quicker than repeated calls to write one byte at a time. There's much less overhead (method calls, IO).
