1. Process
(1) Can act as an input stream or dilute an output stream
(2) Supports reading from the beginning of the file , write
(3) Support reading and writing (insertion) from any location
(4) The RandomAccessFile class needs to specify the access mode:
2. Example
public void RandomAccessFile(String src, String srcMode, String dest, String destMode) {
RandomAccessFile accessFile = null;
RandomAccessFile accessFile1 = null;
try {
accessFile = new RandomAccessFile(new File(src), srcMode);
accessFile = new RandomAccessFile(new File(dest), destMode);
byte[] bytes = new byte[1024];
int length;
while ((length = accessFile.read(bytes)) != -1) {
accessFile1.write(bytes, 0, length);
}
} catch (IOException e) {
e.printStackTrace();
} finally {
if (accessFile != null)
try {
accessFile.close();
} catch (IOException e) {
e.printStackTrace();
}
if (accessFile1 != null) {
try {
accessFile1.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
