Spring Boot

December 17, 2022 / jaswindersingh / 0 Comments

Spring Boot is a framework for building Java applications that makes it easy to create stand-alone, production-grade Spring-based applications. It takes an opinionated view of the Spring platform and third-party libraries, so you can get started with minimum fuss. Most Spring Boot applications need very little Spring configuration.

Spring Boot provides a number of useful features, including:

Embedded Tomcat, Jetty, or Undertow web servers, so you can run your applications in a standalone jar
Automatic configuration of Spring and third-party libraries based on the classpath and various other factors
Command-line tools for running Spring Boot applications
A wide variety of “starter” dependencies that allow you to add jars to your classpath and get automatic configuration for common libraries
Automatic metrics, health checks, and externalized configuration

To get started with Spring Boot, you can create a new project using the Spring Initializr, which is a web-based tool for generating Spring Boot projects. You can choose the dependencies that you need for your project, and the Initializr will generate a project structure and build file for you. Alternatively, you can use the Spring Boot CLI to generate a new project from the command line.

Once you have your project set up, you can use the Spring Boot Maven or Gradle plugins to build and run your application. Spring Boot also provides a number of developer tools, such as the Spring Boot DevTools, which can be useful for live reloading and debugging your application during development.

What is an API?

December 17, 2022 / jaswindersingh / 0 Comments

An API (Application Programming Interface) is a set of rules and protocols that specifies how two software systems should interact with each other. It defines the way in which one system can access the functionality or data of another system, and allows developers to build applications that can communicate with other software or services.

APIs are commonly used to allow different software systems to work together, or to allow developers to access the functionality of a particular service or platform. For example, a social media platform might provide an API that allows developers to access user data or post updates on behalf of a user.

APIs are often designed as a set of functions or methods that can be called by other software, and they usually include detailed documentation that explains how to use them. APIs can be used to expose data or functionality over the internet, so that they can be accessed by remote systems or devices. They are an important part of modern software development and are used in a wide range of applications and industries.

How to use an if-else statement in Java:

int num = 5;

if (num > 0) {
  System.out.println("num is positive");
} else {
  System.out.println("num is not positive");
}

In this example, the if statement checks to see if the value of num is greater than 0. If it is, the code inside the first set of curly braces ({ }) will be executed and the message “num is positive” will be printed to the console. If num is not greater than 0, the code inside the else block will be executed and the message “num is not positive” will be printed.

An if-else statement is a basic control flow construct that allows you to execute different blocks of code depending on whether a certain condition is true or false. It has the following syntax:

if (condition) {
  // code to be executed if condition is true
} else {
  // code to be executed if condition is false
}

You can also include an optional else if clause to check for additional conditions:

if (condition1) {
  // code to be executed if condition1 is true
} else if (condition2) {
  // code to be executed if condition1 is false and condition2 is true
} else {
  // code to be executed if both condition1 and condition2 are false
}

My First Java Program

Welcome to Java Programming world. Let’s learn how to write our first Java program. We’ll first talk about the requirement you need to set up for your development work.

1. IDE / Code Editor

IDE stands for Integrated development environment. It helps you speed up your development work. It also helps with the syntax using intellisense. Code editor is an advanced Text editor that is light weight, does not bring anything extra than you require to start your programming. It helps you reduce the complex part of understanding IDE at initial stage and you get to know more about how code compile and runs. Personally, I feel code editors are better to start the programming than switching to IDE on first day.

Laravel is one among the top PHP frameworks used today for the web development. May it be developing dynamic websites with multiple modules or collection of REST APIs for a mobile app, you will always find Laravel at top choices.

Though i am writing up this series of posts on Laravel 5.2 , greater version have been released. To start with Laravel, you need to have some good knowledge of Object Oriented Programming in PHP. Laravel depends on Composer for installing all it’s dependencies(packages).
