Is it true or false - one problem with OOPS is that once a class is created it can never be changed?
If would have to say false. You would usually add a number of getters/setters to dynamically modify the contents of an object. You can also often respecify one object as another to allow access, for example, to its parent modifiers. You can also build a new class which inherits an existing class and builds upon it.

What is true about true about abstract data type Object of an abstract class type cant be created. We can derive classes from these abstract classes Object of an abstract class t?
True - an instance of an abstract class cannot be created. False - derive (subclass) from a class, not the object (the instance).
True or false All methods in an abstract class must be abstract?
False. In fact, it is possible to have no abstract methods in an abstract class.
The methods cannot have the same name in java true or false?
False. Methods in a class can have the same name as long as they have a different signature. You cannot duplicate method code inside a class but you can always have methods that have the same name but a different signature. Ex: Here I have created two methods in a class that have the same name "sum" but have a different argument types, and return types and hence perfectly allowable in a java class. Public class PolymorphismExample { public int sum(int a, int b){ return a + b; } public double sum (double a, double b){ return a + b; } }

Is it true that a derived class inherits all the members of its base class?
