Socket Closed Error

[mackey333]

Assuming that socket is Socket which may or may not be closed or connected and inputStream = socket.getInputStream().

if (socket.isClosed() || !socket.isConnected())
{
	return null;
}
			
try
{
	i = inputStream.read();
}
catch (Exception e)
{
	System.out.println(e.printStackTrace());
				
	return null;
}

How is it possible for inputStream.read() to throw this error?

java.net.SocketException: Socket closed
        at java.net.SocketInputStream.socketRead0(Native Method)
        at java.net.SocketInputStream.read(SocketInputStream.java:129)
        at java.net.SocketInputStream.read(SocketInputStream.java:182)

Shouldn't the if statement catch this?

inputStream = socket.getInputStream() may throw an error, if the socket is closed.

So you should check for (socket.isClosed() || !socket.isConnectd()) before doing the inputStream = socket.getInputStream()
