In this post, we would like to suggest the skills required to work on Core Java development.
Skills for Core Java Development
I highly suggest you to watch my YouTube video to understand more about the Java Developer Road Map - Learning Path for Java Developer.
Learn and master in Core Java at https://www.javaguides.net/p/java-tutorial-learn-java-programming.html
Core Java
Core Java is a base for all the Java EE frameworks and technologies so make sure that you have a good foundation in core java.
You can learn and master core Java at Java Tutorial | Learn Java Programming with Examples
Data Structures and Algorithms
Data Structures and Algorithms are the building blocks of any programming language.
As a programmer, you should have a good understanding of data structures and algorithms.

Java Testing
Check out the JUnit framework and Mokito for unit testing in Java. As a Java programmer, you should have good knowledge of testing your core logic using the JUnit framework.
To learn and master the JUnit framework at JUnit tutorials
Knowledge on Databases
As a core Java developer, you should have good knowledge of databases.
Here are the commonly used relational databases and No SQL databases:
RDBMS:
- MySQL
- PostgreSQL
- MS-SQL server
- Oracle
No SQL Databases:
- MongoDB
- CouchDB
- Elastic Search
Design Patterns(GOF)
- Creational Patterns for the creation of objects;
- Structural Patterns to provide relationships between objects
- Behavioral Patterns to help define how objects interact.

Desktop Application Development
In the Java community, you have Swing and JavaFX to develop desktop-based applications.
Swing is legacy library for building the desktop app and JavaFX is modern so we suggest you use JavaFX for desktop applications.
