  Introduction to Java JDBC JDBC stands for Java Database Connectivity. JDBC API is a Java API which is used to access tabular data, especially which are stored in the relational database. JDBC works with Java on platforms like Windows, MacOS, and UNIX. What is JDBC? JDBC is used for connecting java programming language with databases. JDBC library has APIs for each task, which is mentioned below. Creating a connection to a database. Creating statements for SQL or MySQL. Executing queries using SQL or MySQL in the database. Viewing & modifying the resulting records. JDBC provides a complete set of an interface which allows access to the database. It can also be used by different types of executables, they are as follows: Java Applications Java Applets Java Servlets Java ServerPages (JSPs) Enterprise JavaBeans (EJBs). All these executables are able to use a JDBC driver to access a database. The java.sql package contains classes and interfaces for JDBC API. Following i...

  Introduction to Servlets Servlets are the Java programs that run on the Java-enabled web server or application server. They are used to handle the request obtained from the webserver, process the request, produce the response, then send a response back to the webserver.  Properties of Servlets are as follows: Servlets work on the server-side. Servlets are capable of handling complex requests obtained from the webserver. Servlet Architecture is can be depicted from the image itself as provided below as follows:  The Servlet Architecture The servlet high-level architectural diagram is shown below. Let’s have a look at how each component contributes to the operation of a servlet in more detail. Client : The client in the design above serves largely as a channel, making HTTP requests to the server and then processing the response it receives. The web browser, as shown in the diagram, is our client. Web server : A web server’s major purpose is to process th...

    Q. Explain JDK, JRE and JVM?   Q.Why is Java ‘write once and run anywhere’(WORA)? Java applications are called WORA (Write Once Run Anywhere) . This means a programmer can develop Java code on one system and can expect it to run on any other Java-enabled system without any adjustment. This is all possible because of JVM. How Java is WORA: In traditional programming languages like C, C++ when programs were compiled, they used to be converted into the code understood by the particular underlying hardware, so If we try to run the same code at another machine with different hardware, which understands different code will cause an error, so you have to re-compile the code to be understood by the new hardware. In Java, the program is not converted to code directly understood by Hardware, rather it is converted to  bytecode(.class file), which is interpreted by JVM, so once compiled it generates bytecode file, which can be run anywhere (any machine) which has...
