I'm new to JAVA and Android, sorry for dumb questions, and for my poor English

When i try to compile the code, it says that i must override the run method in both Server and Client classes. Or try to delete the @Override parameter it says

When i delete the @Override parameter, i can compile the code but it gives "java.net.SocketException : Permission Denied" error.

How can i resolve the problem ?

I also added the

<user-permission android:name="android.permission.INTERNET" />
<user-permission android:name="android.permission.NETWORK" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_MULTICAST_STATE" />

to the manifest.xml .

i get this error on DDMS
