3. Learn DSA Fundamentals

Data structure is a fundamental building block for all critical operations on data. It is the branch of Computer Science that deals with arranging large datasets so that they can be accessed and modified as per the requirements. Learning DSA helps to improve your coding capabilities and problem-solving approach and enhance your real-world project development techniques.

Data Structures

  • Arrays: A collection of elements of the same data type stored at contagious memory locations that can be randomly accessed with their index number.
  • Linked Lists: A series of connected nodes that are randomly stored in the memory.
  • Stack: Works on theLast In, First Out(LIFO) principle.
  • Queue: Works on the First In, First Out (FIFO) principle.
  • Graphs: It is composed of a set of vertices( V ) and a set of edges( E ).
  • Trees: They are also collections of vertices and edges, but there can only be one edge between two vertices.

4. Front-end development with Java

Front-end development is also referred to as client-side development. It means building a website or online application's User Interface (UI). It determines how each website element will appear and work. Everything you see when you visit a website, such as the buttons and UI components, media, messages, forms, and animations, is produced under the front end.

There are three fundamental front-end technologies that any front-end developer must know. The following are:

  1. HTML: It is the basic building block of web pages. You can build a single web page for the whole application using HTML. It is used to create any website's "skeleton" or foundation.
  2. CSS: CSS stands for Cascading Style Sheets, which allows you to apply styles such as colors, fonts, layouts, and animations to your web pages. It also allows you to create responsive websites that adjust their design and styles based on the resolution and orientation of the user's device.
  3. JavaScript: It increases the website's interactivity. You may design dynamic UI components using JavaScript. It determines what the page will do. It is a lightweight, open, and cross-platform programming language used by developers worldwide to build excellent websites.

  • Vue: Vue is a Javascript-based framework for building extensive user interfaces. It can power sophisticated Single-Page Applications (SPAs).

5. Back-end development with Java

The back end stores and arranges data and also ensures that everything on the client side of the website works fine. It is mainly the part of the website we cannot see and interact with.

Java consists of some popular frameworks for backend development. They are:

  • Spring: You can build applications from “plain old Java objects” (POJOs) and apply enterprise services non-invasively to POJOs. It provides comprehensive infrastructure support for developing Java applications to help you focus on application-level business logic. There's no need to worry about deployment environments.
  • Spring Boot is a module of the Spring framework that reduces development, unit test, and integration test time for programming standalone, production-grade Spring-based applications. There is no requirement for XML configuration (deployment descriptor).
  • Hibernate is an object-relational mapping tool for Java. It maps an object-oriented domain model to a relational database, eliminating the need for complex SQL queries for data persistence and retrieval. Hibernate provides its own query language (HQL), which is similar to SQL.

7. Knowledge of Databases

Databases are collections of organized data stored on a computer system. You need to perform CRUD(Create, Read, Update, Delete) operations on data present in databases. So, it's essential to have a good understanding of DBMS. There are several types of databases, including relational, NoSQL, object-oriented, hierarchical, network, and graph databases.

  • MySQL is a multithreaded, multi-user, open-source relational database management system based on Structured Query Language(SQL). It provides MySQL Connector/J to connect client apps developed in Java.
  • PostgreSQL is an advanced open-source object-relational database that supports both relational (SQL) and non-relational (JSON) queries. PostgreSQL JDBC driver connects a Java program to the PostgreSQL database server.
  • MongoDB is an open-source NoSQL database management system written in C++. It provides a Java driver and Spring Data MongoDB for seamless integration with Java.
  • MS-SQL Server: Microsoft developed this Relational Database Management System(RDBMS). It is designed to run on a central server so that multiple users can access the same data simultaneously.

8. Familiarize with Cloud Computing Concepts

Cloud computing has emerged as a critical component of modern software development in today's quickly changing technological landscape. It eliminates the need for individuals and businesses to self-manage physical resources themselves and only pays for what they use.
