class Test
{
private Demo d;
void start()
{
d = new Demo();
this.takeDemo(d); /* Line 7 */
} /* Line 8 */
void takeDemo(Demo demo)
{
demo = null;
demo = new Demo();
}
}When is the Demo object eligible for garbage collection?

Question

Option D is correct. By a process of elimination.Option A is wrong. The variabledis a member of theTestclass and is never directly set to null.Option B is wrong. A copy of the variabledis set to null and not the actual variabled.Option C is wrong. The variabledexists outside thestart()method (it is a class member). So, when thestart()method finishes the variabledstill holds a reference.

Accepted Answer

After thestart()method completes

Answer

After line 7

Answer

After line 8
