Java Code Names

Yesterday I was crawling web and found some intersting things about java. Firstly when java was release its name is Oak. After some time the creator of java found the name Java.
I found some of the intersting things like the code names of the reeases of the java which I am going to describe below.

You can these names on the sun website.
Here is the brief history of java. Some of you wanted to know that how many packages are there in java when it is officially released well here are the some facts.
Java 1.0 - 212 classes in 8 packages
Java 1.1 - 503 classes in 23 packages
Java 1.2/2.0 - 1,520 classes in 59 packages
Java 1.3 - 1842 classes in 76 packages
Java1.4 - 2991 classes in 135 packages
Java 5.0 - 3562 classes in 166 packages


  1. Should not there be Mustang-horse instead of Mustang-car? :)

  2. Hi

    Sorry for that!! You are right it is horse and not car


  3. The chance of them knowing Chelsea football club back then was very unlikely.

    I'd say it's more of an area in London, and not the football club. After all, they call it soccer!

Getting height and width of image in Java

Yesterday I was working on something that requires manipulation of image for getting its properties. After searching over the internet I found a very intersting class on Java i.e ImageIO and BufferedImage class. These classes are good enough to manipulate images. there are many other claases also. But what I need i got it from these. I found many developers searching over internet for getting properties of image and there is no good small example for that. Thats why I thought why not creating a simple code to manipulate the image and help the developers. Here is the small code that helps to get the height and width of the image. Enjoy it!! import java.awt.image.BufferedImage; import; import; import javax.imageio.ImageIO; public class GetImage { public static void main(String[] args) { try { File f = new File("E:/Vinod/Docs/Pics/krishna_01.jpg"); BufferedImage image =; int height = image.getHeight(); in

SSL in Spring Boot using GoDaddy certificate on EC2

In this article, we will be going to see how we can achieve the HTTPS in the spring boot application . You will get lots of items on how to use the self-generated certificate with Spring Boot. But today we are going to use the CA generated certificates with the Spring Boot so that our application will work on HTTPS. We need the following things to work: CA certificates including, private key and certificate. In this article, we are using the GoDaddy wild card certificate. Spring Boot application OpenSSL library Convert the certificate and private key to PKCS 12 First of all, we need to convert the CA certificate to .p12 format . We need to have OpenSSL on the system to work with command. Also, we need to have all files in the same directory where we are running this command. The command required to covert the same: openssl pkcs12 -export -in [ceritificate-name] -inkey [private-key] -name [host] -out [new-file.p12] Here replace the values: [ceritificate-name] with

Struts 2 Hello World Example

I had seen many new deveopers struggling against struts2 hello world example. So I decided to write a small example. Below are the required libraries to run this example which are easily availabel struts2-core- xwork-core-2.1.6 commons-logging-1.0.4 commons-logging-api-1.1 freemarker-2.3.8 ognl-2.7.3 commons-fileupload-1.2 The structure of the applictaion which I am following is (Eclipse IDE) Struts2Demo |---src | |----org | | |----vinod | | | |----action | | | | |----HelloWorld।java |---struts.xml |---WebContent | |---jsp | |---HelloWorld।jsp |---index.jsp |---WEB-INF | |---lib | |---web.xml Struts 2 in Action It is true that different IDE's use different structure, but at last when war is build they follow same structure. Lets start... import com.opensymphony.xwork2.ActionSupport; public class HelloWorld extends ActionSupport { String greetings = null; public String execute() throws Exception { setGreetings("Hel
