What is the cloud? Why cloud?
The short answer is that it's somewhere at the other end of your internet connection – a place where you can access apps and services, and where your data can be stored securely. The cloud is a big deal for three reasons:
It doesn't need any effort on your part to maintain or manage.
It's effectively infinite in size, so you don't need to worry about it running out of capacity.
You can access cloud-based applications and services from anywhere – all you need is a device with an internet connection.
This is important because there's a shift going on from office-based work to working on the home or move.
How cloud computing works
With a cloud app, you just open a browser, log in, and start working.
That means a field sales representative using cloud-based CRM can get all the information they need from their mobile device.

Bean life cycle in Java Spring
The lifecycle of any object means when & how it is born, how it behaves throughout its life, and when & how it dies. Similarly, the bean life cycle refers to when & how the bean is instantiated, what action it performs until it lives, and when & how it is destroyed. In this article, we will discuss the life cycle of the bean.
Bean life cycle is managed by the spring container. When we run the program then, first of all, the spring container gets started. After that, the container creates the instance of a bean as per the request, and then dependencies are injected. And finally, the bean is destroyed when the spring container is closed. Therefore, if we want to execute some code on the bean instantiation and just after closing the spring container, then we can write that code inside the custom init() method and the destroy() method.

What is ApplicationContext?
ApplicationContext is an interface for providing configuration information to an application. There are multiple classes provided by springframework that implements this interface and helps us use configuration information in applications. ApplicationContext provides standard bean factory lifecycle capabilities. An important capability which we will be using in below code example is, class implementing ApplicationContext should scan for ApplicationContextAware beans and invoke setApplicationContext by passing an implementation of its instance.

Cosmetic issues are present on UI part and most of the time they are very much visible. For example: spelling mistake, grammar mistake, font size, colours, tab order, text overlapping etc. Importance of testing cosmetic bugs.
Cosmetic Fault means a Fault which does not prevent the Software operating in accordance with its technical specification.

SQL Constraints
SQL constraints are used to specify rules for the data in a table.
Constraints are used to limit the type of data that can go into a table. This ensures the accuracy and reliability of the data in the table. If there is any violation between the constraint and the data action, the action is aborted.
Constraints can be column level or table level. Column level constraints apply to a column, and table level constraints apply to the whole table.

Software customisations can be cosmetic and functional. Cosmetic changes don't interfere with the business logic and touch only the design and visuals, like for example changing color schemes, images, fonts, hiding registration fields, etc. Functional changes usually require both visual changes and logical.

Taking note of it today I’m starting my own blog website www.cybersandy.com on which *I will be sharing basic information on today’s cyber crime and saftey tips to get secure.* Hoping ur positive response as previously u shown to my telegram channel.
*One safety tip may save your hard earned money & life so stay connected and feel free to ask*
*Note:- I’m not an expert author this is just small effort on request & suggestions of many friends & cyber victims hoping ur positive response, support and understanding*

What is Static Method in Java?
Static method in Java is a method which belongs to the class and not to the object. A static method can access only static data. It is a method which belongs to the class and not to the object(instance). A static method can access only static data. It cannot access non-static data (instance variables).
A static method can call only other static methods and can not call a non-static method from it.
A static method can be accessed directly by the class name and doesn’t need any object
A static method cannot refer to “this” or “super” keywords in anyway

Static variable in Java is variable which belongs to the class and initialized only once at the start of the execution. It is a variable which belongs to the class and not to object(instance ). Static variables are initialized only once, at the start of the execution. These variables will be initialized first, before the initialization of any instance variables.

What is Static Block in Java?
The static block is a block of statement inside a Java class that will be executed when a class is first loaded into the JVM. A static block helps to initialize the static data members, just like constructors help to initialize instance members.
