Java BigInteger variable -

-

in code have check if string valid number following

try{     new bigintger(numericstring);  }catch(numberformatexception e) {   throw numberformatexception; }

i know sort of hack/workaround whatever it, wanted know

new bigintger(numericstring) must creating object in heap if assign value variable biginteger val = new bigintger(numericstring) variable val stored ?

it sounds basic not able imagine difference between two.

val reference object itself, object stored in heap , pointer stored in stack.

the actual value of val in stack address of object in hep.

the new reserved word in java, says reference returned, in first case dont save object usual created in stack collected in short while. in second case, while val still in stack , pointing object, stay in heap
