Questions on Garbage Collections

[Nikhil Jain]

Hello Friends,

I find really confusing when I tried to solve questions like "How many objects are eligible at garbage collection". Can you please suggest me some trick

Secondly in question like

obj a=new Integer();
boj b=new Long();
a=null; ....1
a=b; ....2

Will the object a be eligible for gc at line 1?

thanks
