Java client python server socket programming

Question

I have a client program in java that sends a message \"Hello\" to python server.

Java code

    import java.io.*;  
    import java.net.*; 
    public cla         


        

Answer 1

you are getting 'Hello' from client.

if ( msg == "Hello" ):
    print("Hii everyone")
else:
    print("Go away")

Answer 2

The problem is that you have to specify the decryption UTF-8 in the Python server and then you should use dout.writeBytes("Hello Server") in the Java client.

Answer 3

Just Use proper syntax. Since you are sending "Hello", "Go away" will be your output.

if ( msg == "Hello Server" ):
    print("Hii everyone")
else:
    print("Go away")

Answer 4

because the string you get on the server side has 2 hidden characters at the beginning, so you must remove these 2 characters before comparing it.

if ( msg[2:] == "Hello" ):

Answer 5

In the Java code you have written

dout.writeUTF("Hello");

But the Python server expects "Hello Server" to print "Hii Everyone".

Change Java Client code to

dout.writeUTF("Hello Server");
