Contents [ hide ] What is SQL Injection, and how can you prevent it? SQL Injection is a malicious attack where an attacker manipulates input data to execute unintended SQL statements. It can lead to unauthorized access, data breaches, and data manipulation. To prevent SQL Injection, follow these best practices: 1.1. Use Prepared Statements: Prepared statements or parameterized queries separate SQL code from data input, preventing attackers from injecting malicious SQL code. Here's an example in PHP: $stmt = $pdo->prepare('SELECT * FROM users WHERE username = :username'); $stmt->bindParam(':username', $username); $stmt->execute(); 1.2. Sanitize User Input: Validate and sanitize user input

Java interview questions - Must to know concepts

Contents [ hide ] How does Java achieve platform independence, and what is the underlying principle? Java programs can run on diverse operating systems and hardware setups without requiring modification. This feat is primarily achieved through the concept of the Java Virtual Machine (JVM). The Java Virtual Machine (JVM) The JVM acts as a bridge between the Java code you write and the underlying hardware and operating system . When you compile your Java code, it is translated into an intermediate form called bytecode, which is not tied to any specific platform. The JVM then comes into play. It takes this bytecode and dynamically translates it into machine-specific instructions that the host system can execute. This means that a Java program can be written once and executed on any system with the appropriate JVM for that system. Example: Running a Java Program on Different Platforms Consider a simple Java program that calculates the sum of two numbers: package codeKatha

Introduction- We will learn here Spring Data JPA, perform CRUD operation, Clear concept of Relationship mapping like one-to-many, many-to-one with Example. Spring Data JPA is a powerful framework that simplifies the process of working with relational databases in Java applications. It provides an easy-to-use API for working with JPA, allowing developers to focus on their business logic instead of worrying about the details of how JPA works. With Spring Data JPA, you can easily define entities that map to database tables, and then use them to perform CRUD (create, read, update, delete) operations on those tables. In addition, Spring Data JPA provides support for more advanced features like querying and pagination, making it an excellent choice for both small and large projects. Contents [ hide ] In this blog, we will explore Spring Data JPA by building a sample application that uses it to manage users and packs. But, before let

Java interview questions for 5 years experience

Contents [ hide ] What is difference between Heap and Stack Memory in Java, and shed light on their utilization? In Java, memory management plays a crucial role in determining how objects are stored and accessed during program execution . Heap and Stack Memory are two distinct regions where different types of data are managed. Understanding their differences is essential for efficient memory utilisation and managing object lifecycles. Stack Memory Stack Memory is a region used for storing method calls, local variables, and references to objects . It operates in a Last-In-First-Out (LIFO) manner , resembling a stack of items. Each method call creates a new frame in the stack, containing variables specific to that method. Stack Memory is relatively fast for allocation and deallocation because it follows a strict order. However, it has limited space and is typically used for small, short-lived data. Primitive data types and references to objects are often stored here. Ex
