Q12.
1.public void count(){
2.for(int i=1;i<10;i++){
3.String tmp=Integer.toString(i);
4.System.out.println(tmp);
5.}
6.System.out.println("BOOM!");
7.}
When the program reaches line 6,how many of the String objects created in line 3 are eligible for garbage collection?(Assume the System.out object is not keeping a reference)
(a)None
(b)1
(c)8
(d)9
The answer mentioned is (c).Should'nt it be (d) because,8 objects are eligible for garbage collection when control is within the for loop scope.Once control moves out of the for block scope,the reference to the ninth object is lost thus,making the last String object(ninth object)too eligiible for garbage collection.
Pls let me know ur opinion.
Thanks.

You are right. Also just have a search with the word "BOOM" and you will get a lot of explanations for the answer

Hey !
U can look up "BOOM" in the search and get to a lot of such
code. In addition to this, Please LOOK at the Question, if
there is any code like System.gc() or not, and then at what
point in the code you are talking abt the objects etc etc
