Hi,

I have confusion about following two cases

How many objects will be eligible for GC just after the method returns?

public void compute(Object p)
{
Object a = new Object();
int x = 100;
String str = "abc";
}


When does the String object “ hi ” instantiated on line 2 become eligible for garbage collection?
public class Hello {
String greeting = “hi”;
public static void main(String [] args) {
Hello h = new Hello();
h.greeting = null;
System.gc();
return;
}
}


The answer to first is
"abc" is a string literal which goes to the string pool and is not GCed.

I want to clarify whether the same holds for second also. Will the local string and instance member string both not be GCEed?

Yes, neither of them will be GCed.
HTH,
Paul.
