debugging with intellij idea: a comprehensive tutorial by anton arhipov (adapted & expanded)
this tutorial aims to provide a comprehensive understanding of debugging in intellij idea, inspired by the teachings of anton arhipov (author of "java performance companion"). we'll cover various debugging techniques, explore idea's powerful features, and provide practical code examples to solidify your understanding.
*why debugging is crucial*
debugging is an essential skill for any software developer. it allows you to:
*identify and fix errors:* uncover the root cause of unexpected behavior in your code.
*understand code flow:* trace the execution path of your program to gain a deeper understanding.
*verify assumptions:* confirm that your code is behaving as you expect, particularly in complex scenarios.
*optimize performance:* find bottlenecks by observing execution times at different points in your code.
*1. setting up your debugging environment*
*intellij idea installation:* make sure you have intellij idea (community or ultimate edition) installed.
*project setup:* create a java project in intellij idea or open an existing one.
*2. the basic debugging workflow*
*breakpoints:*
*what they are:* markers in your code where execution will pause.
*how to set them:* click in the gutter (the area to the left of the line numbers) to set a breakpoint. you'll see a red dot appear. alternatively, you can press `ctrl+f8` (windows/linux) or `cmd+f8` (macos) on the desired line.
*disable/enable:* click a breakpoint again to disable it, or right-click and choose "disable". you can also disable all breakpoints by clicking the "mute breakpoints" button in the debug toolbar.
*conditional breakpoints:* these breakpoints only trigger when a specified condition is met. right-click on the breakpoint and enter a boolean expression in the "condition" field.
*logpoints (non-breaking breakpoints):* introduce ...
