2 days ago · When a Java application creates an object, it is allocated memory from the heap. The heap is a shared resource, meaning that all threads in the application can access and modify it. The JVM manages the heap memory, including garbage collection, which automatically frees up memory by removing unreferenced objects.
4 days ago · Garbage collection is a widely used technique that frees the programmer from having to know the lifetimes of heap objects, making software easier to produce and maintain. Many programming languages rely on garbage collection for automatic memory management.
2 days ago · This common question checks your understanding of how generational garbage collection works in Java: Minor GC – Performs garbage collection on the young generation only. This is fast since the young gen is small and contains many short-lived objects. Major GC – Performs garbage collection on the old generation in addition to young.
3 days ago · The class represents a group of objects having similar properties and behavior. For example, the animal type Dog is a class while a particular dog named Tommy is an object of the Dog class. In this article, we will discuss Java objects and classes and how to implement them in our program.

4 days ago · From Java 7 onwards, the Java String Pool is stored in the Heap space, which is garbage collected by the JVM. The advantage of this approach is the reduced risk of OutOfMemory error because unreferenced Strings will be removed from the pool, thereby releasing memory.
3 days ago · In Java, the Collection interface (java.util.Collection) and Map interface (java.util.Map) are the two main “root” interfaces of Java collection classes. What You Should Learn in Java Collections?
5 days ago · In computer programming, there is a technique called garbage collection. “Garbage collection (GC) is a memory recovery feature built into programming languages such as C# and Java . A GC-enabled programming language includes one or more garbage collectors (GC engines) that automatically free up memory space that has been allocated to objects no longer needed by the program.
