Well, when you make an object, it is stored on the "heap". When that object has no reference variables, it is found by the garbage collector and deleted.

When does Garbage collection occur in java?
No one can force garbage collector to free memory, A java object is subjected to garbage collection when it can not be reached by the program in which it is being used. Programmer can request for garbage collection by System.gc() but JVM doesn't guarantee that is will start immediatelyActually, the specific method for GC and how it will be run is dependent on the JVM implementation being used.For instance, Sun (now Oracle)'s Hotspot JVM has several different GC designs, one of which (the RealTime engine) can be immediately triggered via a System.gc() call. Each type of GC will have different triggers and thresholds as to when it will be run, which allows the user to pick the GC option that they think will be least disruptive and most effective for their particular application.You must read the JVM documentation for your particular VM to see what available GC options there are, how each GC method works, and what the various thresholds are.
What is garbage collection answer?
Garbage collection is the phrase used to describe automatic memory management in Java. Whenever a software program executes (in any programming language for that matter), it uses memory in several different ways. We're not going to get into Computer Science 101 here, but it's typical for memory to be used to create a stack, a heap, in Java's case constant pools, and method areas. The heap is that part of memory where Java objects live, and it's the one and only part of memory that is in any way involved in the garbage collection process. So, all of garbage collection revolves around making sure that the heap has as much free space as possible. For the purpose of the exam, what this boils down to is deleting any objects that are no longer reachable by the Java program running. When the garbage collector runs, its purpose is to find and delete objects that cannot be reached. If you think of a Java program as being in a constant cycle of creating the objects it needs (which occupy space on the heap), and then discarding them when they're no longer needed, creating new objects, discarding them, and so on, the missing piece of the puzzle is the garbage collector. When it runs, it looks for those discarded objects and deletes them from memory so that the cycle of using memory and releasing it can continue.
Give the brief introduction of garbage collection?
Garbage collection in java is nothing but the process of freeing up unused memory from the JVM memory heap. Every time an object is created, it is allocated some space in the memory. Once the use for that object is over, that memory space needs to be released so that it can be used by other objects. In Java, this process is automated and the JVM takes care of doing this. Once in a while, a program that performs this garbage collection runs and frees up memory for other objects to use. All objects whose references are no longer used are cleared.
What is the collective noun for garbage?
The collective noun is a heap of garbage or a pile of garbage.
What is a collection of stones called?

What are stored in heap memory?
Objects are stored in heap.
Why smells bad on the garbage?
Explain why we will smell bad oddor when decaying heap of garbage
What is the difference between allocating memory through heap and malloc?
Nothing, malloc does allocate memory from the heap.
What do you mean by garbage collection in data structure?
all classes and variables created in a program are put on something called the Heap, which is stored in main memory (RAM). The Garbage collector gets rid of any class or variable that becomes impossible to reference ever again in the program. For example, say you have a main method and from there you call another method, any local variables created in that other method will be put on the heap while they are in use, ie that function is running. As soon as the method ends, the Garbage collector will come and "release" the memory where those variables were for use in other parts, because you can never access them again when the method finishes.
What is heap -short?
The microprocessor architecture divides the memory into distinct areas. Heap is one of them. This is where you can statically/dynamically allocate memory.
What is the collective nouns for rubbish?
There is no standardized collective noun for a group of rubbish. However, collective nouns are an informal part of language; any noun that suits the context can function as a collective noun; for example, a heap of rubbish, a bag of rubbish, a bin or rubbish, or barrel of rubbish.
Where the heap memory is allocated in c?
Main Memory (RAM).
