thanks for correcting me. Anonymous class can implement only one interface or can extend only one class. My question is why only one interface?

Anonymous inner class can extend only one class and can implement only one interface. Please correct me if i am wrong. if not, please do let me know why only one interface or one class

Thanks Christophe

Hi Jesper,

thanks for the guidance

class Inc{
public static void main(String argv[]){
Inc inc = new Inc();
int i =0; inc.fermin(i);
i = i++;
System.out.println(i);
}
void fermin(int i){
i++;
}
}

In above problem 0 is printed on console.

if we will use other variable j=0 & if we say i=j++; then j will incremented to 1

Please guide me in above case

Thank you very much

List<String> myList= new ArrayList<String>();

we can also create ArrayList using ArrayList object reference.

ArrayList<String> myList=new ArrayList<String>();

Then why such polymorphic-interface reference is used to create such concrete collections object.

Thanks a lot for the helpful information .

I want to know how much depth of Garbage Collection, Thread synchronization concepts is neccessary for SCJP5. To score maximum on questions including above concepts what more preparation is needed along with its basic info.

These are concepts which I find bit tedious. If anyone can guide Please share the thoughts.
