Java 64 Now

: 64-bit pointers (references) are larger than 32-bit ones. This can increase memory usage and slightly slow down cache performance because less data fits into the CPU cache.

When developers see the phrase they usually aren't talking about a specific JDK version. Instead, they refer to running Java applications on a 64-bit architecture using the 64-bit Java Virtual Machine (JVM). While 32-bit Java served us well in the early 2000s, modern applications—especially in big data, cloud microservices, and enterprise backends—demand the vast memory space and performance optimizations that 64-bit Java provides. java 64
