In the "New Project" dialog, select "Java" from the list of project types on the left-hand side. Then, select the version of the JDK that you have installed on your computer and click on "Next".

Select Project Type

Step 2: Configure Project Settings

In the "Project SDK" section, make sure the JDK that you have installed is selected. Then, click on "Next".

Configure Project Settings

Step 3: Create a New Java Class

In the "Create New Class" dialog, enter "HelloWorld" as the class name and click on "OK".

Create New Class

IntelliJ IDEA will create a new Java class file with the name "HelloWorld.java" and the following content:


public class HelloWorld {
    public static void main(String[] args) {

Server-Side Pagination with React-Table and Spring Boot JPA with H2 Database

Pagination is a common technique used to split large amounts of data into smaller, more manageable chunks. With server-side pagination, data is retrieved from the server in smaller batches, reducing the amount of data transferred over the network and improving application performance. React-Table provides a wide range of built-in features such as sorting, filtering, pagination, row selection, and column resizing. These features can be easily configured and customized to fit specific requirements. For example, you can customize the sorting behavior to handle multiple sorting criteria, or you can add custom filters to the table to handle complex data filtering scenarios. Additionally, React-Table provides a flexible API that allows developers to extend its functionality with custom hooks, plugins, and components. This means that you can easily add custom functionality to the table, such as exporting data to CSV or integrating with external data sources. In terms of styl...
