How to Start Learning Java from Scratch: A Step‑by‑Step Guide

This guide explains how to begin learning Java from scratch, distinguishing two learner types: those already familiar with programming languages and those with no prior coding experience, and advises the latter to follow the advice presented.

For programmers who already know another language, the article warns against superficial learning and emphasizes the importance of building a solid foundation before advancing.

For newcomers without any programming background, the article offers a step‑by‑step approach, starting with understanding Java's history, selecting a readable printed book (avoiding low‑efficiency e‑books), and optionally choosing a training institute.

The guide also discusses self‑study techniques, recommending video courses from Dongfang Roll teachers as easy‑to‑understand resources, and suggests using WeChat for additional support.

When choosing a Java book, it advises reviewing the table of contents, shortlisting several titles, comparing their content (noting that many beginner books share 60‑70% of material), and purchasing only if you can comprehend 80‑90% of the material.

To start the self‑learning journey, the article stresses reading at least ten pages daily, following the code examples in the book, and practicing until you can write the code without looking at the book.

After completing the first book, it recommends watching Java fundamentals videos to reinforce the basics, likening solid foundations to building a sturdy house.

Finally, the article alerts learners to join a Java study group (group number 495273252) for questions and resource sharing, encouraging community learning.
