We put a junior developer through a Java interview... with an AI interviewer 👀 New video is up. I ran a full mock interview with a community member, but the twist is the interviewer was an AI. Real questions, real pressure, real feedback at the end. We covered the stuff every junior gets asked: - The four pillars of OOP - Encapsulation and how immutability ties into it - Why the String class is immutable (it's not just performance) - ArrayList vs LinkedList and the real tradeoffs - The Stream API He held his own, but there were a couple of moments where he started rambling under pressure, which is honestly one of the most common things I see in real interviews. Watch it here 👉 https://youtu.be/1YBfizdkYls Then tell me in the comments: What's the one Java interview question that caught you off guard? Or if you've got an interview coming up, drop it below and the community will help you prep. Let's get more of you from junior to hired 🚀

Hello everybody 🤠 I want to test a program which receives a file containing a string object specified by the user and which produces a file containing another string object. Let's assume the business logic of the program is delimited in one single method. I have a question when it comes to creating unit tests for this use-case : how can i code a test which input is a file containing a string object i want to specify and which output is a new file containing another string object representing the result of this treatment ? Are there alternatives for this use-case for JUnit within a springboot application and for JUnit within a simple java core application ? Thank you for your help ! 😁
