Write a Java program that implements a simple Client/Server application.?

Question

The client sends data to a server(remote machine). The server receives the data, uses it to produce a result, and then sends the result back to the client. The client displays the result on the screen. Implement the above scenario for Swapping two numbers.

Swapping of two numbers



static void swap(int i,int j){

int temp=i;

i=j;

j=temp;

System.out.println("After swapping i = " + i + " j = " + j);

}

public static void main(String[] args){

int i=1;

int j=2;

System.out.prinln("Before swapping i="+i+" j="+j);

swap(i,j);

}

Answer 2

Hi,



import java.io.*;

import java.net.*;

class Client

{

public static void main(String ar[])throws Exception

{

Socket s=new Socket(InetAddress.getLocalHost(),10000);

System.out.println("enter the radius of the circle ");

DataInputStream dis=new DataInputStream(System.in);

int n=Integer.parseInt(dis.readLine());

PrintStream ps=new PrintStream(s.getOutputStream());

ps.println(n);

DataInputStream dis1=new DataInputStream(s.getInputStream());

System.out.println("area of the circle from server:"+dis1.readLine());

}

}

import java.io.*;

import java.net.*;

class Server

{

public static void main(String ar[])throws Exception

{

ServerSocket ss=new ServerSocket(10000);

Socket s=ss.accept();

DataInputStream dis=new DataInputStream(s.getInputStream());

int n=Integer.parseInt(dis.readLine());

PrintStream ps=new PrintStream(s.getOutputStream());

ps.println(3.14*n*n);

}

}

dude try to use arraysto store each input and print each value of array without using prinln , e.g using system.out.print(array[1]+" "+array[2]+" " + ...araay[5])"
