The class given below tests your understanding of classes and their objects initialization.Given below the sample code :
class SuperClass {
SuperClass() {
}
public class SubClass {
SubClass() {
}
}
}
Which is the correct way to declare the object of public "Subclass" , which can be use outside the "Superclass" ?
1. SubClass Sub = new SuperClass().new SubClass();
2. SubClass Sub = new SuperClass.SubClass();
3. SuperClass.SubClass Sub = new SuperClass.SubClass();
4. SuperClass.SubClass nbc = new SuperClass().new SubClass();
Answer :
(4)
Explanation :
If the "Superclass" is declared as "static" it will be declared like this :
SuperClass.SubClass Sub = new SuperClass.SubClass();
But if the "Superclass" is declared as "public" it will be declared like this :
SuperClass.SubClass nbc = new SuperClass().new SubClass();
