4️⃣ Can you force Garbage Collection?
Not really, but you can request it using:
System.gc();
Runtime.getRuntime().gc();
⚠️ No guarantees—JVM decides when to run it!

1️⃣6️⃣ Memory Management with Arrays
When you reassign an array, the old one might be removed from memory if it’s no longer needed (Java’s garbage collection!). This keeps memory use efficient. 🧹 #JavaMemory#GarbageCollection
Java memory management poses 2 limitations: limited heap sizes & garbage collection overhead. We dive into the elastic memory conversation in one of our recent whitepapers: bit.ly/3yUk5gZ#Java#JavaMemory#DataStorage
JVM memory has multiple regions, some are known (Young Generation, Old Generation, Metaspace). In this video clip, you will learn why your java process will occupy more than -Xmx value you had configured. ow.ly/fIxx30ojR6j#JavaMemory#YoungOldmetaspace
