I want to implement any one sorting algorithm using TCP/UDP on Server application and Give Input On Client side and client should sorted output from server and display sorted on input side. Here, I have created program for multiplication of a number. I am not getting how to pass int array from client side and receive the same array. How can I do that.It would be a great help. Thank in advance.

BufferedReader and BufferedWriter are for character streams.
Consider using other ways, like ObjectInputStream and ObjectOutputStream.
(DataOutputStream / DataInputStream could be good too)

I am learning Java and I'm writing an example client - server application.
The sokcket connection is fine, everything works well until the second message from the client app. It does not reach the server. If I start another client it also succeed at the first message, and fails at the second.
Anyone has an idea? Thanks in advance!
Server code:

public class Server {

while (true) {

socket = serverSocket.accept();

Your while is misplaced in your server code, and in fact you need 2 while loops:
one for accepting new clients
one for manage several messages by client
In pseudo code it gives you:
while (true):
accept new client
while (client connected):
read message from client
write back message to client
close client socket
If you want to use threads, then it's the inner while loop task which you have to delegate to a new thread.
Note: accept is blocking until a new client comes. That why you could send only one message by client.
Your server is not set up to handle this. You are reading one line, then discarding the connection for the GC, without closing it. The server, reading one line, then ignores all other lines and starts listening for the next connection.
Also, consider using threads.
I am trying to write a simple and basic Java program where a client sends the server a string and the server is supposed to respond with a reversed string. I am sure I have the correct program structure and flow but my server is not read the string from my client. I have narrowed the problem to this line on the server side: string = inputStream.readLine();
Here is my code. What could be the problem?
Server1.java
import java.io.*;
import java.net.*;
class Server1 {
public static void main(String[] args) throws Exception {
String string = null;
ServerSocket myServerSocket = new ServerSocket(4000); //Create Socket
System.out.println("Server Running...");
Socket clientSocket = myServerSocket.accept();
DataInputStream inputStream = new DataInputStream(clientSocket.getInputStream());
PrintStream outputStream = new PrintStream(clientSocket.getOutputStream());
do {
string = inputStream.readLine();
if(string!=null){
//using StringBuilder method to reverse string
StringBuilder input = new StringBuilder();
// append a string into StringBuilder input1
input.append(input);
// reverse StringBuilder input1
input = input.reverse();
// print reversed String
for (int i = 0; i < input.length(); i++) {
outputStream.println(input.charAt(i));
}
}
} while (true);
/*outputStream.println("exit");
outputStream.close();
inputStream.close();
myServerSocket.close();
System.out.println("Server Closed!");*/
}
}
Client1.java
import java.io.*;
import java.net.*;
import java.util.Scanner;
class Client1 {
public static void main(String[] args) throws Exception {
Scanner sc = new Scanner(System.in); //Object to read keyboard input
String string = null, response = null; //Variable to store string
Socket mySocket = new Socket("127.0.0.1", 4000); //Create Socket
DataOutputStream outputStream = new DataOutputStream(mySocket.getOutputStream());
DataInputStream inputStream = new DataInputStream(mySocket.getInputStream());
System.out.println("Client Running...");
do {
System.out.println("Type in a string and Press Enter...");
string = sc.next();
outputStream.writeBytes(string);
response = inputStream.readLine();
if (response != null) {
System.out.println("Server Response: " + response);
}
} while (true);
}
}
The problem is that in this line string = inputStream.readLine();
it is searching for a line and if you wont add "\r\n" at the end of your massage it will keep searching for the lines end

when you close the input or the output socket stream,
when you close the object, which is directly or indirectly wrapping the input or the output socket stream, e.g. BufferedReader or Scanner.

//keep listens indefinitely until receives 'exit' call or program terminates
while(true){

//creating socket and waiting for client connection
Socket socket = server.accept();
//read from socket to ObjectInputStream object

socket.close();
//terminate the server if client sends exit request
if(message.equalsIgnoreCase("exit")) break;
}
System.out.println("Shutting down Socket server!!");
//close the ServerSocket object
server.close();
}
}
But it is not reading the String which I send from the android app. Instead when I submit from app, the java program shows the following errors:
Exception in thread "main" java.io.StreamCorruptedException: invalid stream header: 54657374

How can I fix this. Where is my error lays?? Is it on Server side or client side?? Please help me guys.
PROBLEM ANALYSIS:
You use a PrintWriter for sending from the client, but you use an ObjectInputStream on the receiving side of the server. These two are not compatible.
You have to use a pair of Writer and Reader together or a pair of ObjectOutputStream and ObjectInputStream, but you can't mix them.
SOLUTION:
We're going to use pairs of Writer and Reader. The client side already uses a Writer and a Reader, so we only need to change the server side.
On the server side, instead of the ObjectInputStream, use a BufferedReader:
BufferedReader reader = new BufferedReader(new InputStreamReader(socket.getInputStream()));
reader.readLine();
Moreover, use a PrintWriter instead of the ObjectOutputStream on the server side for sending back to the client:
PrintWriter writer = new PrintWriter(new BufferedWriter(
new OutputStreamWriter(socket.getOutputStream())),
true);
writer.println(str);
Alltogether, then the server side looks like this:
import java.io.IOException;
import java.io.BufferedWriter;
import java.io.BufferedReader;
import java.io.OutputStreamWriter;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.lang.ClassNotFoundException;
import java.net.ServerSocket;
import java.net.Socket;
public class SocketServerExample {
//static ServerSocket variable
private static ServerSocket server;
//socket server port on which it will listen
private static int port = 5000;
public static void main(String args[]) throws IOException, ClassNotFoundException{
//create the socket server object
server = new ServerSocket(port);
//keep listens indefinitely until receives 'exit' call or program terminates
while(true){
System.out.println("Waiting for client request");
//creating socket and waiting for client connection
Socket socket = server.accept();
// //read from socket to ObjectInputStream object
// ObjectInputStream ois = new ObjectInputStream(socket.getInputStream());
// //convert ObjectInputStream object to String
// String message = (String) ois.readObject();
// System.out.println("Message Received: " + message);
BufferedReader reader = new BufferedReader(new InputStreamReader(socket.getInputStream()));
String message = reader.readLine();
System.out.println("Message Received: " + message);
// //create ObjectOutputStream object
// ObjectOutputStream oos = new ObjectOutputStream(socket.getOutputStream());
// //write object to Socket
// oos.writeObject("Hi Client "+message);
PrintWriter writer = new PrintWriter(new BufferedWriter(
new OutputStreamWriter(socket.getOutputStream())),
true);
writer.println("Hi Client "+message);
//close resources
reader.close();
writer.close();
socket.close();
//terminate the server if client sends exit request
if(message.equalsIgnoreCase("exit")) break;
}
System.out.println("Shutting down Socket server!!");
//close the ServerSocket object
server.close();
}
}
Use this on the client:
PrintWriter out = new PrintWriter(socket.getOutputStream(), true);
Use this on the server:
BufferedReader is = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));
String message = is.readLine();
Use flush() after sending anything.
out.println(str);
out.flush();
I have received error message after the client side successful received one message from server side. The error message is: Exception in thread "main" java.net.SocketException: Software caused connection abort: recv failed
It seems in client class, line = inFromserver.readLine(); would not receive any message from server, making it become "null". But I dont know why. Could somebody please help me?

You are sending byte array from client to server and reading string on server side.
Insert somthing in your byte array and then Convert your byte array into String
String str = new String(dataToTransfer,int offset, 1000000);
then write:
outToServer.println(str);
