Question

Why doesn’t Android throw a SocketException when the socket is closed?

I get an IOException if there is no permission added in the manifest file for Internet but when I grant it the Internet permission and check my program it gets stuck at

Socket obj=new Socket("*****",3000);

if the socket is closed? Why is that?
It should not keep waiting for the socket to open instead throw an exception

try {
    Socket obj=new Socket("*****",3000);
} catch (UnknownHostException e) {
    e.printStackTrace();
} catch (IOException e) {
    e.printStackTrace();
}

Answer 1

SocketException is a subclass of IOException, so the exception is being caught by your second catch clause which is the reason you don’t see it.
