TCP/IP is one of the most important protocol as its backbone of HTTP, internet and most of the communication happens today. It's also important from technical interview perspective, you might have already seen difference between TCP and UDP multiple time during interviews ( I have seen). I believe every programmer, not just Java developer should know what is TCP/IP protocol? How it works and the below points I am going to mention. These are basic points and most of you already know but during Interview I have found many developers who doesn't really know what TCP/IP offers and how it works and what are the pros and cons of TCP/IP protocol. That's where, I think this article will help you. Anyway, let's jump into technical details now.
How to send HTTP Request from a Java Program - Example Tutorial
If you are thinking is it possible to send an HTTP request from a Java program and if yes, how to send a simple HTTP GET request in Java, then you have come to the right place. In this article, I'll show you how you can use the HttpURLConnection class from the java.net package to send a simple HTTP request in Java. But, first, let me answer your first question, is it possible to send an HTTP request in Java? Yes, it's possible and you can send any kind of HTTP request like GET, POST, PUT, DELETE, HEAD, or PATCH. The java.net package provides a class called HttpURLConnection, which can be used to send any kind of HTTP or HTTPS request from Java program.
How to Fix java.net.SocketException: Broken pipe in Java - Cause and Solution
Hello guys, If you have worked in a client-server Java application then you may be familiar with the "java.net.SocketException: Broken pipe" error, It is one of the many socket-related errors you will see on the server-side application log. This error comes intermittently when many clients are connecting to a server and many clients closing the connection before a response is fully transferred. Some of the common causes of java.net.SocketException: Broken pipe exception includes
- The user closed the browser before the page loaded.
- Their internet connection failed during loading.
- They went to another page before the page loaded.
- The browser timed the connection out before the page loaded (would have to be a large page).
How to Fix with java.net.SocketException: Connection reset Exception in Java? Examples
Hello guys, for the past few months, I have been writing about different socket-related errors on Java applications, and today I am going to talk about another common socket-related exception in Java - java.net.SocketException: Connection reset Exception. There is no difference between exceptions thrown by the client and server. This is also very similar to the java.net.SocketException: Failed to read from SocketChannel: Connection reset by a peer but there is some subtle difference. The difference between connection reset and connection reset by peer is that the first means that your side reset the connection, the second means the peer did it. Nothing to do with clients and servers whatsoever
How to Convert Hostname to IP Address in Java - InetAddress Example
Hello guys, today, I am going to teach you about one interesting class from java.net package, the InetAddress. If you have never used this class before, let me tell you that it's an abstraction to represent an Internet address and it encapsulates both hostname and IP address. Since converting an IP address to hostname or hostname to IP address is a very common requirement, Java developers should know about this class, and, in general about java.net package, which contains many other useful class for networking and client-server applications. So, what is the best way to learn new APIs like java.net? Well, by writing small programs like this, which has a small focus and let you explore things. They are super useful and that's how I have learned the majority of Java API.
How to Find IP address of localhost or a Server in Java? Example
In today's Java programming tutorial, we will learn some networking basics by exploring the java.net package. One of the simple Java network programming exercises, yet very useful, is to write a program to find the IP address of the local host in Java. Sometimes this question is also asked to find the IP address of the Server on which your Java program is running or find the IP address of your machine using Java etc. In short, they all refer to localhost. For those who are entirely new in the networking space, there are two things to identify a machine in a network, which could be LAN, WAN, or The Internet.
