hi all....although this is a widely discussed topic..i was hoping i cud get some clear insights here. I was wondering how a class can extend a class and the class Object at the same time. please help...thanks and regards

to be a little clearer, if class A extends class B, you can say "A is a B". if B then extends C, "B is a C". by the transitive property, you can say "A is a C". and so on and so on... if the class definition doesn't SAY it extends anything, it extends Object by default. so, A extends B extends C extends Object.
