Why is the young generation divided into Eden and Survivor (S0, S1)?

In Java JVM, the Young Generation is divided into three areas: Eden and two Survivors (S0 and S1). This is done to optimize the work of the garbage collector.

• Eden — where new objects are created. Most objects quickly become unnecessary and are removed here.
• Survivor Spaces (S0 and S1) — two areas between which objects that have 'survived' a garbage collection are alternately moved. This helps track the age of objects and decide when to move them to the old generation.

This division allows for efficient memory management, minimizes pause times during garbage collection, and improves application performance.
