Question

我正在为在Java服务器中连接的游戏构建Android客户端。我在服务器中有这个代码

for (int i = 0; i < diceRolled.length; i++) {
            diceRolled[i] = (int) ( 1 + Math.random() * 6);
}
List<int[]> dice = Arrays.asList(diceRolled);
output.writeObject(dice);

创建一个Object，它将它通过套接字传递给客户端。但在客户端我需要将其转换回数组。我试过了

try {
        ObjectInputStream what = new ObjectInputStream(socket.getInputStream());
        int[] myDice = (int[]) what.readObject();
    } catch (StreamCorruptedException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (ClassNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

但它没有用。我的错误在哪里？

Answer 1

服务器发送 List<int[]> dice = Arrays.asList(diceRolled);

申请尝试“重建”int[] myDice = (int[]) what.readObject();

你应该转换为不列出数组

在客户端中通过套接字将对象转换为数组
