![]() ![]() The old generation is home to objects have been around long enough. There is still memory in the old generation. Note only the memory space for the nursery is full. When the nursery is full, garbage collection cleans it out. The nursery is the younger generation where the new objects are stored. Young-generation, old-generation helps prioritize objects for garbage collection by dividing Java Heap Space into two generations. Clearing them ensures they don’t take up space in the Heap. These are objects that are no longer being used. Garbage collection works to free memory by clearing any by objects without any references in the methods. It is managed by two concepts: Garbage collection and young-generation, old-generation. That means all objects can be referenced from anywhere in the application. When an object is created, it is always created in Heap and has global access. Java runtime uses it to allocate memory to objects and Java Runtime Environment (JRE) classes. The memory is used as long as the application is running. It is created by the Java Virtual Machine when it starts. The Java Virtual Machine (JVM) divides memory between Java Heap Space and Java Stack Memory in a way that only uses memory that’s needed. To keep application memory requirements lean, it is partitioned in ways that require less memory and allows the application to run more quickly. Simply designating enough memory to hold every value declared and run each method would lead to a bloated application. ![]() Each time an object or variable is declared, it needs more RAM. Java applications need a certain amount of RAM on a computer to run. ![]()
