Skills for Core Java Developer

In this post, we would like to suggest the skills required to work on Core Java development.

Skills for Core Java Development

The below diagram shows skills required you to work on 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.

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.

To learn and master Data Structures and Algorithms in Java at Data Structures and Algorithms in Java

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)

In software engineering, a design pattern is a general repeatable solution to a commonly occurring problem in software design. A design pattern isn't a finished design that can be transformed directly into code. It is a description or template for how to solve a problem that can be used in many different situations.

As a core Java programmer, you should know the commonly used design patterns in Java.
    The GoF Design Patterns are broken into three categories: 
    1. Creational Patterns for the creation of objects; 
    2. Structural Patterns to provide relationships between objects
    3. Behavioral Patterns to help define how objects interact.
    Learn and master all the GOF design patterns at All GOF design patterns.

    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.
