raf.write報錯
public class RadomAccessFileTest {
public static void main(String[] args) throws IOException {
File file = new File("C:\\Users/Administrator/Desktop/a.txt");
RandomAccessFile raf = new RandomAccessFile(file,"rw");
System.out.println(raf.getFilePointer());
raf.seek(raf.length());
raf.write("a");
}
}

RandomAccessFile 一次只能寫一個字節，"a"是個字符串，可以換成'a'或者"a".getBytes();
getBytes()方法可以設置編碼類型如gbk,utf-8等
