JDBC Overview

-

 JDBC stands for Java Database Connectivity, which is a Java API that provides a standard way for Java programs to interact with databases. JDBC enables Java programs to connect to and manipulate data in relational databases like MySQL, Oracle, and SQL Server.

JDBC is based on a driver-based architecture, where a driver is a software component that enables communication between the Java program and the database. There are four types of JDBC drivers: Type 1, Type 2, Type 3, and Type 4. Each driver has its own advantages and disadvantages, and developers must choose the appropriate driver based on their requirements.

JDBC provides a set of interfaces and classes that enable developers to execute SQL queries, update data, and retrieve results from the database. Some of the core JDBC interfaces are Connection, Statement, PreparedStatement, CallableStatement, ResultSet, and ResultSetMetaData.

To use JDBC in a Java program, developers must first load the appropriate driver, establish a connection to the database using a Connection object, and then use Statement or PreparedStatement objects to execute SQL queries or updates. Finally, the program retrieves the results using a ResultSet object.

JDBC is a powerful API that allows Java developers to create robust and scalable database applications. It provides a standard way to interact with databases, which makes it easier for developers to switch between different database systems.

Cryptography API

-
Java offers a comprehensive set of cryptographic functionalities through its `java.security` package. This package provides various classes and interfaces for encryption, decryption, key generation, digital signatures, and more. Here are some key classes and concepts within Java's Cryptography API: 1. **Message Digests (Hashing):** Classes like `MessageDigest` help generate hash values for data using algorithms like MD5, SHA-1, SHA-256, etc. 2. **Encryption/Decryption:** The `Cipher` class allows encryption and decryption using various algorithms like AES, DES, RSA, etc. 3. **Key Management:** Java provides classes such as `KeyGenerator` for generating symmetric keys, `KeyPairGenerator` for key pairs (for asymmetric encryption), and `KeyStore` for managing keys and certificates. 4. **Digital Signatures:** The `Signature` class helps create and verify digital signatures. Here's a simple example demonstrating encryption and decryption using Java's Cryptography API: ```java im...

Java Applet Overview

-
  An applet in Java is a special type of program that is designed to be executed within a web browser. Applets are written in the Java programming language and can be embedded within an HTML page using the <applet> tag. When the HTML page containing the applet is loaded in a web browser, the applet code is downloaded and executed by the Java Virtual Machine (JVM) built into the browser. Applets are often used to provide interactive functionality on a web page, such as games, animations, and data visualization. They have access to a limited set of features and resources provided by the web browser, such as user input events and graphics libraries, but are restricted from accessing resources on the user's computer or network. In recent years, the use of applets has declined in favor of other technologies such as JavaScript, HTML5, and CSS. However, applets are still supported by some web browsers and can be a useful tool in certain situations where other technologies may not be...

Vector in Java

-
  In Java, a vector is a resizable collection of objects, similar to an array, but with some additional functionality. A vector can grow or shrink dynamically, and can be accessed using an index just like an array. To use a vector in Java, you first need to import the java.util.Vector package. Then you can create a new vector object using the following syntax: java Copy code Vector<Object> vectorName = new Vector <Object>(); Here, Object can be replaced with any data type that you want to store in the vector. For example, if you want to store integers, you can use: java Copy code Vector<Integer> intVector = new Vector <Integer>(); To add elements to the vector, you can use the add() method: java Copy code intVector.add( 1 ); intVector.add( 2 ); intVector.add( 3 ); To access an element in the vector, you can use the get() method: java Copy code int element = intVector.get( 0 ); // returns the first element (1) You can also use other methods provided...
