Mutliple inheritance in Java

[narain ashwin]

I am suspecting my understanding that JAVA doesn't support multiple inheritance

Consider this class

public class MyClass
{
}

We can say that this class extends the Object class.But if I modify the above class to implement threading

public class MyClass extends Thread
{
}

seems like MyClass extending both Object class (implicitly) and Thread class (explicitly).Doesn't that means multiple-inheritance?

one java class can not be extended from more than one superclass.

class A extends B,C is not working !!

but you can do eg:

class A implements B,C,...

seems like MyClass extending both Object class (implicitly) and Thread class (explicitly).Doesn't that means multiple-inheritance?

your class extends Thread and Thread extends Object or something else ..

a class cannot DIRECTLY extend more than one class. it can only have one parent. However, it can have a grand-parent, a great-grand-parent, etc.
