Introduction to JavaBeans
Reusability is one of the vital aspects of any software components model. Developers are always focusing on writing the software once and use that software whenever needed in the future. In Java, JavaBeans is the class with a purpose to develop reusable software components for the Java platform.
On Java platform, JavaBeans are nothing but the classes that consist of numerous objects into a single object (Bean). JavaBeans have Zero-argument constructors and are serializable. With getter and setter methods JavaBeans allow access to properties. In the application builder tool, JavaBeans can be manipulated visually.
As stated, JavaBeans helps in reusing software components in developing an application. With the help of JavaBeans, one can reuse software components that are written by other developers. This eliminates the need for understanding inner workings. As Beans consists of numerous objects into a single object, one can directly access this object from various places. Its maintenance is easy. The software component model deals with the creation and reuse of the software components to build an application. With the help of the builder tool, one can develop new beans or use existing beans to create an application. One can directly use these beans into the software.
If you are still confused, then consider the example of a worker assembling a car and radio is one of the components. Instead of manufacturing the radio from scratch, a worker can directly assemble radio to the car. This eliminates the need for manufacturing a radio for assembly.
Components of JavaBeans
Components of Java Beams are nothing but the class that contains the definition of beans. These classes have specific design convections. It consists of events, methods, persistence, properties. Non-GUI based and GUI based components are the two types of components. The classes are discussed below:
- Properties: This attribute consists of a label, font, color, size, display size, etc. It determines behavior, appearance, and the state of Beam.
- Methods: Methods in JavaBeans are similar to the normal Java methods. It does have any specific naming convention.
- Events: Events in JavaBeans is similar to Swing event handling.
- Persistence: It helps in storing the state of JavaBean.
What Can You do with JavaBeans?
As there are no restrictions on the capabilities of JavaBeans, one can design any type of component in this. With JavaBeans, one can reuse software components in any environment. From simple functions like spelling correction to complex functions like forecasting stock market, beans can perform different functions. Beans can be visible or invisible to the end user. With a set of distributed components, beans can work autonomously. From set data points software can generate a pie chart. This is the example of a locally executed bean. Bean that delivers real-time price information about the stock market is also one of the examples of this.

Beans can also be used to give interactive capabilities to web-based applications. Beans can run on any operating system. It can run inside numerous application environments such as word processors, browser and many other applications. A UI component such as trees, graphical buttons, and trees give a lively touch to applications and eliminates the need for writing custom components. One can develop the JavaBeans with Beans Development Kit (BDK) from Sun
Advantages of JavaBeans
1. Run anywhere; write once- Java Beans eliminates the need for writing software again and again.
2. One can work with JavaBeans on Numerous local platforms which make it valuable in the global market.
3. JavaBeans can capture the events that are sent by other objects. It enables the object communication.
4. An application developer is able to control Methods, events, and the properties of any Java beans.
5. Zero hassle at run time with auxiliary software, one can configure beans during design time.
6. Reusable: One can make a persistence configuration setting in JavaBeans. Persistent storage and restored later can save the configuration setting of the bean.
Required Skills for JavaBeans
- It is vital to have a proper understanding of computer fundamentals, algorithms, structure, etc. One should have an understanding of numerous operating systems of the computer.
- One must have a proper understanding of the Java 1.1 event model. One should be aware of different Java technologies.
- While developing operation names in the Java Bean class, it is important to follow certain ‘naming conventions.
- One should be aware of the information of the builder tools to develop JavaBeans.
- The basic knowledge of different frameworks and fluency coding will surely give one edge in developing JavaBeans.
Career Scope in this Technology
In today’s interconnected world programming language plays a pivotal role in the business world. Java is considered as one of the reliable programming languages in the world. It is a very popular language among developers. The scope and carriers in developing JavaBeans expected to rise in the coming years. Professionals with Java skills have a lot of opportunities in these sectors. Today Java is leading programming language in the back-end market and application development. The future looks promising for all java professionals across the globe. Millions of Java Developers prefer Java for its usability, practicality, compatibility, and ease of use.
There is plenty of Java opportunities present across the globe. Numerous reputed companies like Microsoft, Amazon web services, IBM, Oracle, and many others are always looking for Java professionals.
JavaBean Professionals can make a flourishing carrier in Information Technology. Everyone has different reasons for picking up different technology but having knowledge of JavaBeans surely adds benefit to one’s skill set and also offers a lot of growth opportunities and money.
This post gives information about JavaBean, its process flow, uses, along with the advantages. This technology is helpful in building flexible Java applications. Most of the New Java Development tools support JavaBeans. With technologies such as relational databases and ActiveX, JavaBeans can be used in the tandem.
To summarize, JavaBean is component architecture for Sun’s Java Language. JavaBean enables Java professionals to write applications easily and quickly. One can write any component as a JavaBean and then plugged into it into an application.
