Write Java like a senior developer with these 10 tips. Most of these features exist since Java 9–21 but developers still don't use them. Records, var, switch expressions — are you using these? Drop a comment if you knew all 10 👇 #java #programming #softwareengineering #coding #javadeveloper

This one-page infographic covers everything from properties and methods to use-cases and performance. 💡 Key takeaway: ArrayDeque is a fast and efficient choice for stack and queue operations with O(1) performance at both ends. #Java #DataStructures #ArrayDeque #Programming #Coding #Developers #Tech TAP Academy @Bibek Singh

A friend told me new devs were grinding here 6 months to prep for interviews. In my day thought process was more important than syntax. I don’t care if you can remember if that language uses semicolons. I want to know if you jump right in without clarifying requirements. I want to see you correct yourself. I want you not to want to work someplace that treats you like a robot (because they will probably replace you with ai if you can’t do those other things).

A for loop that never ends 😳 No initialization. No condition. No update. Still runs forever. In Java, this behaves exactly like while(true). Miss this in real code and your application could hang. How would you stop this loop without using break? 👇 #Java #SoftwareEngineering #CodingTips #Programming #Developers #CleanCode #TechEducation

A common Spring Boot issue developers face: - Multiple beans of the same type This leads to: - NoUniqueBeanDefinitionException Why? - Because Spring doesn’t know which bean to inject. Solution: @Qualifier It allows you to explicitly specify which bean should be injected, removing ambiguity and making your code more predictable. This is also a frequently asked interview question. How do you usually handle multiple beans in Spring? #SpringBoot #Java #BackendDevelopment #CodingInterview #SoftwareDevelopment #Programming #Developers
