After basic Java training, you have many options, either you can study more technologies related to Java or you can study other Java frameworks or you if you are looking for a job then you can prepare for technical interview questions.
If you have learned basic Java that means you have knowledge about core Java, that means you can learn advanced Java also. You also have an option of going into entry-level jobs where you can learn more about Java frameworks and technologies.
Java Technologies That You Can Learn After Learning Basic Java
- Java Server Pages
Java Server Pages is a server-side Java technology. Java Server Pages is used to develop dynamic web pages by controlling the appearance or content of Web pages. The developers of Java i.e. Sun Microsystems uses the term servlet Application Program (API) in place of JSP technology.
Java Server Pages (JSP) technology can also be compared to Microsoft’s Active Server Page (ASP) technology. The only difference is that in the Java Server Page (JSP) technology a Java program that is executed by the Web server is called whereas an Active Server Page contains a script and a script interpreter (such as JScript or VBScript) is interprets that script before sending the page to the user. The suffix.JSP is given to HTML pages that have a link to a Java servlet.
- Servlets
Servlet is a Java technology that is mainly used for creating web applications. Extending the capabilities of a server is the main function of a Java servlet.Servlets have the capability of responding to any type of requests and the most commonly implemented applications are the ones that are hosted on Web servers.
These are the Web servlets which are considered the Java counterpart to other dynamic Web content technologies such as PHP and ASP.NET.
- Multithreading
Multi-threading is similar to multi-tasking, the only difference is that in multi-threading we deal with threads (i.e. the smallest unit of processing). Multi-threading allows a program to run multiple tasks simultaneously within a program.
Java is integrated with multi-threaded efficiently as compared to conventional languages. Multi-threading helps in making Java efficient and increases speed of the processor. Java’s property of multi-threading gives it an edge over other programming languages because threads share a common area of memory, hence consuming less memory space.
Since, Java is differentiated from other programming languages because of multi-threading of Java, therefore, it is an important Java technology that you should learn after learning Basic Java.
- Generics
In generics, the methods and classes in Java are declared as parameters when classes are defined as well as interfaces and methods. These generic classes and methods ae known as type parameters.
The type parameters allows one to re-use the same code with different parameter, similar to the more familiar formal parametersthat are used while declaring methods. In type parameters the inputs are types while in formal parameters the inputs are values. A code that uses generics has a stronger type check at compile time.
Java Frameworks That You Can Learn After Learning Basic Java
- Spring
Spring is a very popular Java framework which helps in creating a high performing application that can be tested, hence it suggested to learn Spring framework after learning basic Java. In order to keep you focused on the important features of your project, Spring does all your trivial tasks and handles all the trivial usability features.
The unique role of this Java framework is that it makes it possible for you to connect various components. Hence, helping you in creating a solution for complex problems.The various features offered by this Java framework are support to traditional database RDMS as well as new NoSQL , cloud support, high security and compatibility to mobile phones.
- Struts 2
Developed by Apache foundation, Struts 2is a Java framework that helps increating flexible web applications that can be easily maintained and is based on standard Java technologies, such as JSP pages, JavaBeans, resource bundles, and XML.Struts 2 is a Java framework that is open source in nature and is widely used in App Development. Struts 2 has a unique collection of utilities and set of JSP custom tag libraries.
This Java framework plays an important role in App Development because it has a core architecture which is simple to work with and can be extended. Struts 2 and Spring MVC are somewhat similar when compared together based on their features, the only difference is that the UI supported by Struts is better and faster when compared to Spring MVC. This is a very old Java framework hence is advised to learn after learning Basic Java.
- EJB
EJB stands for Enterprise Java Beans which is a server side software component in which encapsulation of business logic is done. EJB is a development architecture that helps to build highly scalable enterprise level applications. EJB also ensures robustness of the same.
A runtime environment is provided by Enterprise Java Beans (EJB) for related software components like transaction processing, Java servlets management, computer security and various other web services.
Although, gaining more and more knowledge is always preferred because one can never have enough of knowledge. Java in itself is very vast and powerful. After learning Basic Java you have a lot of things you can gain knowledge about. A few things that can you can learn after learning Basic Java are given afore but there are always more things that you can learn.
