以下程序段执行后将有（）个字节被写入到文件afile.txt中。 try { FileOutputStream fos = new FileOutputStream("afile.txt"); DataOutputStream dos = new DataOutputStream(fos); dos.writeInt(3); dos.writeChar(1); dos.close(); fos.close(); } catch (IOException e) {} 3 5 6 不确定，与软硬件环境相关
try { FileOutputStream fos = new FileOutputStream("afile.txt"); DataOutputStream dos = new DataOutputStream(fos); dos.writeInt(3); dos.writeChar(1); dos.close(); fos.close(); } catch (IOException e) {}
C int 4 char 1 然后加上结束符 1 就是6
