DevOps Real-Time Tip "Confused between JDK and JRE? 🤔

If you're a DevOps engineer, this is VERY important!" "First, let’s understand JDK. JDK stands for Java Development Kit. It provides a complete environment 👉 To write Java code 👉 To compile Java code 👉 To execute Java code So remember this: With JDK — You can WRITE code, You can COMPILE code, You can EXECUTE code."
