   if u have instance variables in class so memory for all instance variable will be allocated in heap. not in stack stack is for method variable

hi,

actually static variables ,local variables ,method parameters are stored in stack.somany stacks are created(one stack per one thread)

instance variables and java objects are stored in heap.only heap is created.

cheers

The JVM allocates memory in two ways1) Stack: for local variables (declared in methods and constructors). this is deallocated once the method exits.2) heap: everytime an object is created using new keyword, it is allocated in the heap. theses have a longer lifespan. it the JVM runs out of space in the heap it gives a Java out-of-memory error.

Hey!NO NO........everytime an object is created using new keyword, it is allocated in the heap. these have a longer lifespan. if the JVM runs out of space in the heap it gives a Java out-of-memory error........................and local variables and methods goes to stack...and this is deallocated once the method exits and variables goes out of scope......

stored in heap and the reference variables are stored in stack.if heap is filled then out of memory exception occurs

Here is my 2 cents worth.


(a) Simply put, all Java Objects are allocated memory in Heap.



(b) Primitives types (not *array* of primitives) and references to objects are allocated on the stack.



(c) Importantly, each thread in the JVM gets it own stack and the VM option



-Xss decides the stack size for each thread.



Note: If the stack size is too small, eventually you see "StackOverflowError".


Example:class FooBar{    
public void get(MyTest obj)   // obj a reference to an object - stack.   
{          
int x = 10;    // Stack         
Vector tmpObj=new Vector(); // Heap         
...         
...   
}
}
 
Note:  tmpObj will be garbage collection based on the rules 
(like reference count and others) that GC maintains to check its life span.
HTH.

Hai All,

   By using new operator we can allocate memory.ex:new A(); this statement

   allocates memory for the class A. suupose A obj;means one reference will be create for the class A.When u write obj=new A(); then only that reference become object.for reference memory will not created.For objects only memeory will be created...

 If i am wrong plz let me know

Thanks and Regards

when a jvm encounter the new keyword then it will try create object in heap only. But String is created in String pool which is one part of the heap.

hi

u asked what actually new does

it creates memory for the variables just nothing but an constructor

it is operator which is used to allocate memory in c++  as per my knowledge is concerned

a. ofcource the object will create on heap. When ever it will have live thread then only it will be on stack

Always object allocated memory in heap and method always memory allocated in stack.

When you declare a variable with new keyword its allocated space in heap.because we dynamically create a variable and we create a variable dynamically its allocated space in heap.

Whenever object is created,It store local and partial results in heap storage(for ex.int a=10) and instance of object is stored in stack as a form of frames.At the time of method invocation, a new frame created and destroy when method invocation is stopped.
