Java debugging tips & tricks
summary
Demos show concrete techniques: live expression evaluation, IntelliJ IDEA’s JShell console and smart step into for lambdas, conditional breakpoints that inject code, and Eclipse / NetBeans equivalents. The debugger mutates private and final fields (even string bytes), can force-return values, track class load/unload and instance counts, mark objects, and create logical views of collections. Measurements claim low overhead when launching in debug mode and examples run interactively so the tricks actually work.
