How To Debug Java Code The Right Way - Eclipse Debugger Full Tutorial

How To Debug Java Code The Right Way With The Eclipse Debugger
Full tutorial on using the Eclipse Debugger!
Do you still just use print statements everywhere to debug your Java code?
Many beginners don't know there's a MUCH better way to debug their Java programs, and it's built into Eclipse and every other modern IDE.
The Eclipse debug tools make debugging your Java programs incredibly simple and (dare I say it) even fun.
In this beginner's Java tutorial video, we'll do a full walkthrough of using the Eclipse Debugging tools.
Learn or improve your Java by watching it being coded live!
Hi, I'm John! I'm a Lead Java Software Engineer and I've been in the programming industry for more than a decade. I love sharing what I've learned over the years in a way that's understandable for all levels of Java learners.

It's a shame that debugging isn't usually explained or taught in most courses even though it's one if not the best tool a developer has. It's a good thing that people like you make videos about this to let learners know about it. I want to share a little tip with everyone: you can use a conditional breakpoint to execute whatever piece of code you like, for example automatically edit a variable's value instead of doing it yourself everytime or log something with a print without even touching the code

[@tibettenballs4962]

its a shame. JS HASSSS NO DEBUGGGERRRR

[@ylananderson6291]

@@tibettenballs4962 it kinda does, any browser should have the dev tools, you have to find your js file in the sources tab and do the debugging thing there. Otherwise for IDEs you can attach the process which is kinda like the first option but you do all the debugging from the ide window

[@tibettenballs4962]

@@ylananderson6291 still sucks, no matter how you package it

[@sairos4057]

I hope someday I can do this, right now as a beginner I couldn't... :(

[@_Anna_Nass_]

I’m in my second year of computer science classes and they’re just now showing us how to use a debugger. They really should show us this stuff earlier. It would have been sooo helpful.

[@davidx5828]

That’s so funny because I did put print statements throughout my code to figure it out 🤣🤣🤣

[@CodingWithJohn]

You're not the only one!

[@findlestick]

Same here, and I thought I was being so clever. 😑

[@bagzhansadvakassov1093]

We all did

[@MrSkinkarde]

The fastest way to debug for me still

[@priyanandshukla8388]

I do the same even after watching this video 😂

[@Redcodes]

I am coding in Java for 2 years and I always used print Statements to Debug. You just changed my entire life with that Video.

[@abscodes9587]

I honestly learnt a lot from this video John. I’ve spent nearly an hour and a half trying things with you and experimenting. PS I was one of the ones that throw print statements everywhere and it kinda gets messy most of the time hahah so thank you!

[@josema294]

Hi John, I've recently start studding coding, computers were my passions since ever, and now I've made the jump and pretend to quit from my job and do this for full time, also recently I've discovered your channel, is a huge pool of knowledge and inspiration for me, some topics are still out of my reach as a new student, but i can appreciate the value of this videos, soon some of them would become gold for me. So congratulations for your efforts, it,s something big, and just want to cheer you up!! i will keep having and eye on your videos even if still cant follow every topic. Thanks!!

[@gunsmass93]

At the moment as far as I looked at KZbin, this is the only one Chanel where you can fully understand what he is talking about. Even if you are new to programing. Thank you verry much for the amazing content and your clean way to explain this amazing things to us! 😇😇😇

[@illiazo]

The fact that I watch your videos just for entertainment and to learn even though I'm not working on a specific task, makes you no less than a great content creator! please keep it up!

[@shirotaku686]

Thanks for the tutorial. I knew most of it except for the conditional breakpoint. I used to help myself by creating dummy if-clauses to check for the condition. Very helpful, especially for beginners!

[@khurrambhatti9470]

Thank you very much. I had been programming for over 7 years without using the debug mode. Even after all tge experience, I always learn something new from your videos.

[@neeve-gg7kz]

Thank you John. This is the first video i am watching to learn how to debug java code and i think i dont have any other video. It is that clear.

[@mraymond5346]

Hi John, as usual, well-explained and fun to watch. Thanks for taking the time to prepare and present the videos. Could you perhaps do one on streams... ? Thank you

[@christyndall2009]

Hey John, thanks a ton for your videos! I am currently an online student pursuing a bachelors in software development and your videos are better than the etexts they use at school. They really make learning Java much easier! I especially love this one and your videos on sorting, but I haven't made it through this series yet and can't wait too. Thanks again and please keep them coming!

[@gladyslemus1798]

I agree with you, watching his video made more sense than the live lecture 😅

John, your videos are probably the most helpful ones I came across. Thank you!

A new thing I learned from here is the conditional break point. Awesome video. Thanks to John.

I am new to Java, but quite good at a few other programming languages. I've been so lazy to learn the conditional breakpoint that I've modified my source codes instead to create the condition. Now that you showed it in such a quick step, I feel quite dumb :-). Thanks for the helpful video!

[@ekjotnanda6832]

Excellent content 👍🏻👍🏻

[@JTBanks]

Really great job with this video!! I can't explain how life changing some of this information is. I was wondering John, at some point in the future would you be willing to do code reviews occasionally? It could help with content, and personally I find myself at a standstill currently in my coding life. My friends and co-workers say my code is good, but I'd really appreciate an unbiased opinion. But, regardless, amazing job, thank you so much!

[@CodingWithJohn]

That's a very interesting idea! I can't guarantee anything, but if you would be willing to potentially have your code shared in a video, you can either leave your code here in the chat or email it to me ([e-mail]), and I'll see if a code review for it might make a good format for a video that would be informative to others.

[@QuadeSan]

Man, you are incredible 10/10

[@jvsnyc]

Quite excellent. While watching I had some "Yeah, but" or "but what about?" moments and I can say that by the end of the video you quite literally covered all of them. Many larger places with more legacy code might have painted themselves into a corner with Eclipse dependencies. I am going to very soon find out for my next/current work environment, but I've worked at least two places where you pretty much were forced to use Eclipse for various reasons, grumbling about how your favorite IDE was better and more productive was optional.

[@CodingWithJohn]

Yep, the comment I've received the most here was, "Why not IntelliJ?" Although I mainly use IntelliJ, I had assumed most newer learners tended to use Eclipse, but that may not be the case anymore. So I'm planning to do a subscriber poll soon to try and get an idea of the most used IDE, and might end up making a switch for future videos.

[@mayankpant1596]

@@CodingWithJohn ..from the first year in university we were told to use intellij because it's more commonly used in the industry nowadays. But here in KZbin most of the guys I have seen use eclipse so I don't really know how true is that.. Tbh it really doesn't matter cause they have mostly the same functionality imo..
