Question

I am implementing a client server application. from the server i am sending a String array, and now i want to read whats in that string array from my client code. How can i do this;

When i print the value from the client i get the output something like [Ljava.lang.String;@120d10

server:

try {
                    PrintWriter r= (PrintWriter) i.next();

                    String[] s={"f","ff"};
                    r.println(s);

                    r.flush();
                } catch (Exception ex) {

                }

client:

try {
                    while ((somestring= r.readLine()) != null) {
                        //When i print it i get something like [Ljava.lang.String;@120d10


                    }
                } catch (Exception ex) {}

You’re trying to println the array of strings, instead of each string in the array. Try something like this on the server:

    try {
                PrintWriter r= (PrintWriter) i.next();

                String[] s={"f","ff"};
                for(String sElement : s)
                {
                    r.println(sElement);
                    r.flush();
                }

            } catch (Exception ex) {

            }
