How to convert a List of Strings to a Comma Separated String with Single Quotes In Java

You can convert a list of strings to a comma-separated string with single quotes around each element in Java by iterating through the list and constructing the desired string. Here's how you can do it:

Explain the 'CASE' expression in Oracle SQL statement

In Oracle SQL, the CASE expression is used to add conditional logic within a SQL statement. It allows you to perform different actions based on different conditions. The basic syntax of the CASE expression is:

Here's an example to demonstrate how to use the CASE expression:

Suppose we have a table named employees with columns employee_id, first_name, last_name, and salary. We want to create a new column called salary_category that categorizes employees based on their salary into three categories: "Low", "Medium", and "High".

Explain Disaggregation with Simple Example

Disaggregation simply means breaking down a whole into its smaller parts. It's like taking apart a Lego set to see the individual bricks. Here's a simple example to understand disaggregation:

Imagine you run a small bakery. At the end of the month, you see you made a profit of $1,000. That's great! But to understand how you got there, disaggregation can be helpful.

Without Disaggregation:

You only know the total profit: $1,000

With Disaggregation:

Break Down Revenue:
- You sold $2,000 worth of bread.
- You sold $1,500 worth of cakes.
- You sold $500 worth of cookies.
- Total Revenue: $4,000

? and ! symbol in Angular

In Angular, both ! and ? serve different purposes and have specific meanings.

!: This symbol is primarily used in Angular template expressions to indicate a non-null assertion. When you use ! after a property or expression, you're telling TypeScript that you're confident that the value won't be null or undefined. It's often used when you know for sure that a value exists, but TypeScript's static analysis cannot infer it.

How to set up a custom domain with Blogger?

Here's a step-by-step guide on how to set up a custom domain with Blogger:

Steps:

Access your Blogger dashboard: Go to https://www.blogger.com/ and sign in using your Google account.
Select your blog: On the left-hand side menu, click on the blog where you want to set up the custom domain.
Go to Settings: Click on the "Settings" option from the menu.
Access "Publishing": Under the "Settings" menu, locate the "Publishing" section.

Two Options for Connecting your Domain:

A. Using Google Domains:

If you purchased your domain through Google Domains, you'll see an option to connect it directly.
Click on "Continue with Google Domains" and follow the on-screen instructions. Google will handle the necessary DNS (Domain Name System) configuration steps.

ROWNUM vs LIMIT in SQL

ROWNUM and LIMIT are both mechanisms used in different database management systems to restrict the number of rows returned by a query, but they are used in different contexts and have some differences:

ROWNUM:
- ROWNUM is a pseudo-column in Oracle databases that returns a unique sequential number for each row retrieved by a query.
- It is typically used in conjunction with a WHERE clause to limit the number of rows returned.
- For example:
```
SELECT * FROM table_name WHERE ROWNUM <= 10;
```
- This query will return the first 10 rows from the table table_name.

Pros and cons of SCSS (Sass) compared to CSS

SCSS (Sass):

Pros:

Variables: SCSS allows you to declare variables, making it easy to reuse values throughout your stylesheets. This promotes consistency and reduces redundancy in your code.
Nesting: SCSS allows for nested CSS rules, which can help to organize and structure your stylesheets in a more hierarchical way, resembling the HTML structure. This can improve readability and maintainability.
Mixins: SCSS supports mixins, which are reusable blocks of styles that can be included in multiple selectors. This enables you to encapsulate common patterns or sets of styles, promoting code reusability and maintainability.
Functions: SCSS includes built-in functions that allow for more advanced and dynamic stylesheet generation. These functions can perform calculations, manipulate colors, and more, providing greater flexibility in your stylesheets.
Partials and Importing: SCSS supports the use of partials, which are separate files containing segments of CSS that can be imported into other SCSS files. This modular approach can help to organize your stylesheets into smaller, more manageable pieces.
Extends: SCSS provides the @extend directive, which allows one selector to inherit styles from another selector. This can help to avoid code duplication and maintain a more DRY (Don't Repeat Yourself) codebase.
