IntelliJ IDEA Tips & Tricks

on YouTube ↗27m

" summary

Live demo shows IntelliJ reading lines from lines.txt into a BufferedReader, building an ArrayList, converting to streams, applying multiple filters, and extracting methods — all using real edits, refactorings and live templates so the example compiles and runs. Highlights include Full Line code completion running locally, customizable live templates, ligature-aware font display, lambda breakpoints in the debugger, and Trace current stream chain to visualize each filter step. Tips for shortcuts include Key Promoter X and the built-in Feature Trainer; examples consistently work and shorten the code.
