Garbage collect with String Objects

[P Malhotra]

Hello everyone

I am using string and I know that we can create string objects by two different ways:

1) String s="Hello"; //Line1
2) String s1= new String("Hello"); //Line2

so if we are using the code written in Line1 that means we are creating a String object in the String literal pool
and
the Line2 will create an String object in Heap

So what is String literal pool ?
Is it like heap or it is a table where we can store actual objects reference.

and

when will garbage collect remove the String objects from the heap


Thanks

Remember objects are always created on heap only. //created in line1 and line2
String pool is an constant memory location which is store the literal objects reference.

Thanks for your reply

and what about the garbage collect if pool is holding the address of the object than when will garbage collect remove the Objects.

You have 2 objects on the heap (i am not too sure about the string pool ..so there might be only 1 object in heap)

The objects are eligible to remove from the memory when they are no longer referenced. Eg. if i say s = null, then there will be no way to get "Hello" object on the heap (assuming there are 2 objects on the heap)

Could please someone clarify how many objects would be in the heap? Thanks

On the real exam GC questions NEVER use objects of type String.
