eden space java heap

What is Eden space in Java heap?
The heap space is divided into the old and the new generation.
The new generation includes the new object space (eden), and two survivor spaces.
The JVM allocates new objects in the eden space, and moves longer lived objects from the new generation to the old generation.
What is -Xmn JVM parameter in java? -Xmn : -Xmn sets the size of young generation.
It will set the size of young generation of JVM heap to 512 bytes.
It will set the size of young generation of JVM heap to 512 kilobytes.

How do I fix Java heap space error?

The easiest solution to remove such error is to increase the memory size of the JVM heap space.
To increase the size of the heap space, use “-Xmx” java options to solve the out-of-memory error.
This configuration will provide 1024 heap space to the application.
