Java Course for Beginners
Programming is one of the most sought-after skills in the information technology domain. If you choose to do any graduation, engineering or commerce, software tools would form some part of your learning and later the job. If you are an expert in programming, your value is up in the job market. To become an expert you can start with a Java course for Beginners.
If you already have some exposure to programming before starting Java, it would be of advantage. If you do not have such exposure, do not worry. You can even start with Java programming as your first language. Once you start learning and understanding it, programming will be fun.
On a more serious note, if you can start mastering language nuances, it will be of great help in the long run. Typically, you might learn Java itself or any other similar programming language in your curriculum. If you develop good skills in Java and top it up with knowledge of frameworks like Spring, you can get a good career after your graduation.
Contents of Java Course for Beginners
If your aim is to develop some working Java application, here is what parts of Java you need to focus on.
When we learn any new language, we start with the alphabet. Then try to construct small sentences and then get on to bigger paragraphs. Similarly, programming languages also have a similar pattern. You will learn constructs like if, else, while, do, for, switch case, arithmetic operators, logical operators, and so on.
One of the greatest advantages of Java programming is that it is object-oriented. Object-oriented programming is better suited for developing large-scale applications which are robust and easier to maintain in the long run.
The course covers object-oriented features like abstraction, encapsulation, inheritance, polymorphism, etc. Using these crucial features you will learn how to create Java applications.
GUI, Exceptions, Collection APIs
Once you are through with OOP concepts, some of the important topics are studied. In the exception handling mechanism, you will know how to handle errors. One can write multi-threaded Java applications using concurrency-related packages. Java AWT or Swing can be used to create graphical user interfaces like forms. A framework like Java collections is handy for using lists or sets of items in any application.
Database Connectivity in Java
Software’s main task is to process data. Take user input, perform calculations based on the business logic and show the output to the user based on the requirement. To store data, we use relational databases like Oracle, SQL Server, MySQL, etc. We know that these databases use SQL(structured query language) for the manipulation of data.
When you want to store or retrieve data stored in such databases in a Java application, you use a package called JDBC. It provides you with various functions to connect to databases. JDBC package also provides you facilities for executing SQL queries, stored procedures, and so on.
Java course should cover how to use features of JDBC and interact with databases. Typically this data may be displayed in a Java application on a desktop or on the web.
Java language is the most in-demand skill proficiency for Java developers. It is one of the most used and leading programming languages that can seamlessly move from one system environment to another. Java frameworks, such as Spring and Hibernate, are gaining unprecedented traction. – Mercer Mettle Tech skills and Trends report
Beyond Java Course for Beginners
Doing a Java course is not an end unto itself. It is just a starting point. Once you master the programming constructs and small application development in Java, you can easily move towards advanced features.
To get a job as a Java developer in the industry, you need to master the following technologies and frameworks in addition to Java. Knowledge of Java would be important from two perspectives: in some companies, you will end up giving a programming test in Java, and secondly, most of the listed frameworks are Java frameworks.
|Web Application Server Side||Servlet, JSP, Spring framework, Hibernet|
|Micro Services||Spring Boot|
|Databases||Oracle/SQL Server/ Mongo DB|
