Examples of java.io.RandomAccessFile.readFully()

java.io.RandomAccessFile.readFully()
Reads bytes from this stream into the byte array buffer. This method will block until buffer.length number of bytes have been read. @param buffer the buffer to read bytes into @throws IOException If a problem occurs reading from this DataInputStream. @see DataOutput#write(byte[]) @see DataOutput#write(byte[],int,int)

        byte[] buf = new byte[5];
        RandomAccessFile raf = new java.io.RandomAccessFile(fileName, "rw");

        raf.seek(0);
        raf.skipBytes(5);
        raf.readFully(buf);
        assertEquals("Failed to skip bytes", "World", new String(buf, 0, 5));
        raf.close();
