Question

我不是一名java开发人员，但我想在这部分代码中修复项目中唯一的警告：

public abstract class SelectorThread<T extends MMOConnection<T, RP, SP>, RP extends ReceivablePacket<T, RP, SP>, SP extends SendablePacket<T, RP, SP>>
{
    protected static final Log _log = new MMOLogger(SelectorThread.class, 1000);

    private final AcceptorThread<T, RP, SP> _acceptorThread;
    private final ReadWriteThread<T, RP, SP>[] _readWriteThreads;


    protected SelectorThread(SelectorConfig sc, IPacketHandler<T, RP, SP> packetHandler) throws IOException
    {
        _acceptorThread = new AcceptorThread<T, RP, SP>("AcceptorThread", this, sc);
        _readWriteThreads = new ReadWriteThread[sc.getSelectorThreadCount()];

        for (int i = 0; i < _readWriteThreads.length; i++)
            _readWriteThreads[i] = new ReadWriteThread<T, RP, SP>("ReadWriteThread-" + (i + 1), this, sc, packetHandler);
    }

    ...
}

警告：

Type safety: The expression of type ReadWriteThread[] needs unchecked
conversion to conform to ReadWriteThread<T,RP,SP>[]

拜托，有人可以帮我解决这个问题，或者告诉我必须知道解决这个问题。我理解上面的行是由<T, RP, SP>修复的，但这不适用于数组。

更新：我看到我的问题是重复的，我的问题是：在数组中使用泛型是不安全的。但是，我如何更改代码来修复此问题？我所有的一切都是

_readWriteThreads = (ReadWriteThread<T, RP, SP>[]) Array.newInstance(ReadWriteThread.class, sc.getSelectorThreadCount());

但是这段代码也给了我一个警告。

你可以添加注释@SuppressWarnings（“unchecked”）
