原标题:Check for incoming data in Java Socket

我写了一份简明的Java聊天,我想检查一下是否有一些数据等待。 BufferedReader。 我读到了NIO,但我根本不理解。 我的一些法典是:

public void Send(String data)
{
    out.println(data);
}

public String Recv()
{
    if (dataIncomming)
    {
        try {
            return in.readLine();
        } catch (IOException e) {
            System.err.println("Send: Error on BufferedReader.readLine() - IOException");
        }
    }
    else return "";
}

我不知道填入<条码>的数据。

最佳回答

使用Stream.Available() 方法。 你们还可能要等到收到适当数量的 by子后再等,这样,read子就没有100%的时间。

while(Stream.Available() != 0); //block until there is data

try{  
    return in.readLine();  
} catch (IOException e) {  
    System.err.println("Send: Error on BufferedReader.readLine() - IOException");  
}
