Install HotSwap Agent for Java 21 (Save Time!)

With HotSwap Agent, you can save on the amount of time it takes you to develop your Java, Kotlin, or JVM based application by allowing for on-the-fly class reloading, practically cutting out compilation and restart time from your process.
In this video, I will show you how to download, install and set up HotSwap Agent for Java 21 using the JetBrains Runtime JDK and IntelliJ IDEA.
HotSwap Agent is amazing, too, because it is a completely free, open-source alternative to a paid, closed source plugin for Java (and the JVM in general) called JRebel, which, unless you're a corporate customer and have hundreds of dollars per year to spare, is basically not an option for you.
This video could save you hours. Enjoy!

IMPORTANT: If you haven't already got HotSwap enabled in your IntelliJ settings, you need to enable it! Go to the IntelliJ settings (Ctrl+Alt+S) > Build, Execution, Deployment > Debugger > HotSwap, and either change "Reload classes after compilation" to "Always" or "Ask".

Thanks, helped me a lot as a java beginner!
It also works with other application configurations. Tried it with Tomcat and as long as the VM options are set and the correct JRE is selected, it works totally fine!
