For example, instead of writing classes with SQL to load, save, and update data using the DAO design pattern, you can simply use the Hibernate framework in your project. It will allow you to deal with just objects while it will load, save, and update data in the background. It's also one of the top Java frameworks in my list of top 10 Java frameworks Programmers can learn.

The 2020 React.js Developer RoadMap - The Complete Guide to become a React Expert in 2020

Top 10 Advanced C++ (CPP) Books for Experienced Developers - Must Read

Once you know C++ and spends a couple of years of programming in C++, you started to feel that you know the basics and have good command over C++ programming. At this time, the programmer goes to two paths, one who chose to do just fire-fighting and daily work and never upgraded or forced to learn new or more by reading books, participating in forums, and giving presentations. The other group of programmers explores new books to learn C++ in detail and after reading a couple of books on this list, they also realize how much of C++ they know is incomplete and incorrect. That's why I recommend experienced C++ developers to read books to complete the journey from a junior developer to a senior developer.

If you have worked in any real-life JAva project which connects to Database using JDBC then you know that JDBC API is not very convenient to use as it requires a lot of boilerplate code. For example, to execute a simple SELECT query, you first need to create a Connection and Statement object to execute the query and iterate through a ResultSet Object to get the result of the query. Finally, you need to close all of these resources to prevent resource leak in Java.

Top 5 Soft Skill and Career Development Books and Courses for Programmers

Most of the software developers, programmers, and coders spend a considerable amount of their time and energy on learning technologies which get obsolete in few years like a new framework or a new programming language but they neglect something more important like soft skills.

Similarly, most of us put a lot of effort to get a job but after that, we don't put much effort to grow on that job, the result is many programmers and software developers stuck in their careers.

Self Join Example - SQL Query to Find Employees Earning More Than Managers - LeetCode Solution

Write an SQL Query to Find Employees Earning More Than Managers
The Employee table holds all employees including their managers. Every employee has an Id, and there is also a column for the manager Id as shown below:

+----+-------+--------+-----------+
| Id | Name  | Salary | ManagerId |
+----+-------+--------+-----------+
| 1  | Joe   | 70000  | 3         |
| 2  | Henry | 80000  | 4         |
| 3  | Sam   | 60000  | NULL      |
| 4  | Max   | 90000  | NULL      |
+----+-------+--------+-----------+

Given the Employee table, write a SQL query that finds out employees who earn more than their managers. For the above table, Joe is the only employee who earns more than his manager because Henry's Manager is Max who earns 90000 which is more than Henry's salary of 80000.

Those skills are quite valuable and just doesn't come when your experience increases, you need to work hard to acquire that. I know many programmers who have been programming for 7 or 8 years, but they still don't pose these skills. Some of them never bother to try, and some of them just don't know how to develop those skills. It's where these books come into the picture.

Difference between Inheritance and Polymorphism in Java and Object Oriented Programming

Both Inheritance and Polymorphism are key OOP concepts and similar to Abstraction and Encapsulation, they are also closely related to each other.

Inheritance refers to the ability for classes or objects to inherit properties of other classes or interfaces. It means you can write code for common functionalities and reuse it at different places by just using Inheritance and not re-writing those codes again and again. For example, you can write code to

Java HashMap ContainsKey and ContainsValue Example - Check if a Key or Value exists in the Map

Hello guys, one of the common problems many Java developers working with HashMap face is about how to check if the Map contains a particular key or value? You can use this to check duplicate keys or just to ensure that you are not overriding current value because if you insert a key that already exists in the HashMap, then you end up overriding its value. Since HashMap also allows duplicate values, it's also possible that the same value may be paired against multiple keys, so just removing a mapping may not be enough to remove that particular value. Not paying attention to these details has actually caused issues in Java application.

Top 5 Books to Learn Groovy for Java Developers - Best Of Lot, Must Read

Groovy is a programming language that is specially created for Java developers with a view to being a fast-paced, scripting companion to Java.

Because of this property, Groovy is heavily used in unit testing of Java application. Some popular unit testing frameworks like Spock is also built on Groovy.

There are also a lot of resources to learn productivity tips, like keyboard shortcuts, and debugging techniques, but there were not many for Intelli IDEA.

One of the questions my reader often ask me is, shall I learn Scala? Does Scala has a better future than Java, or why Java developer should learn Scala and so on.

Top 5 Courses to learn gRPC and Google Protocol Buffer in Java, Golang and C#

Hello guys, you might have heard about the gPRC, the Google Remote Procedure Call solution. It's the latest buzz in the tech circle, and people are talking enthusiastically about it. The buzz is evident because it's coming from Google like Angular, Golang, Flutter, Dart, TensorFlow, and other latest technologies. For those who don't know, gRPC is a super-fast, super-efficient Remote Procedure Call (PRC) system that will help you to develop distributed systems like Microservices. This means you can use gPRC to communicate between your Microservices at super-fast speed.

The server defines service and indicates that it can be called remotely with method parameter and return type and then provides implementation and an RPC server that can handle client calls.
