What is java beans? Differentiate it with java classes

-

.A java bean is a reusable software component written in java that can be manipulated visually in an application builder tool.This idea is that one can start with a collection of such components, and quickly wire them together to form complex programs without actually writing any new code.


A JavaBean is a software component that is written in a java programming language. It is similar to a java except for following differences:

● A JavaBean must adhere to certain conventions regarding property and event interface definitions whereas java classes need to be.

● A builder tool must be able to analyze how a Bean works through the introspection process. This is not necessary for java classes.

● Java Beans must be customizable. It should allow its state to be manipulated at design time. This is not necessary to be true in the case of java classes.

● JavaBeans must implement Serializable interface which is not necessary for java classes.

● Every JavaBean must have one public no-argument constructor which is not true for java classes

What are different steps used in JDBC? Write down a small program showing all steps.

-
 T he fundamental steps involved in the process of connecting to a database and executing a query consist of the following: Import JDBC packages. Load and register the JDBC driver. Open a connection to the database. Create a statement object to perform a query. Execute the statement object and return a query resultset. Process the resultset. Close the resultset and statement objects. Close the connection. These steps are described in detail in the sections that follow. 1. Import JDBC Packages This is for making the JDBC API classes immediately available to the application program. The following import statement should be included in the program irrespective of the JDBC driver being used: import java.sql.*; Additionally, depending on the features being used, Oracle-supplied JDBC packages might need to be imported. For example, the following packages might need to be imported while using the Oracle extensions to JDBC such as using advanced data types such as BLOB, and so on. import o...

Discuss classification or taxonomy of virtualization at different levels.

Taxonomy of virtualization Virtualization is mainly used to emulate the execution environment, storage, and networks. The execution environment is classified into two: – Process-level – implemented on top of an existing operating system.  – System-level – implemented directly on hardware and does not or minimum requirement of the existing operating system. OR,  Virtualization covers a wide range of emulation techniques that are applied to different areas of computing. A classification of these techniques helps us better understand their characteristics and use  V irtualization is mainly used to emulate  ● Execution Environments: To provide support for the execution of the programs eg. OS, and Application.  ○ Process Level: Implemented on top of an existing OS that has full control of the hardware  ○ System Level: Implemented directly on Hardware and do not require support from existing OS.  ● Storage: Storage vi...

Pure Versus Partial EC

Pure Versus Partial EC EC takes several forms depending on the degree of digitization (the transformation from physical to digital). Companies utilizing pure EC conduct all of their business online. Businesses utilizing partial EC conduct a portion of their business online and a portion of their business off-line OR,    Pure E-electronic commerce refers to a situation where a business transacts its business activities PURELY online. that is, the goods or services sold do not have any physical presence. take a business that sells software, for example, you just pay and download, or one that sells music files online. Partial E-Commerce on the other hand refers to a slightly opposite situation where a business has an online presence, but still has a physical location for the goods and services it sells. For example, Amazon, Walmart, and any other you can think of. you buy the goods online but receive them physically.                   ...
