Hello, I want some help for those questions for Java language. Please give me some examples to let me understand :

ArrayList Section

write code to create and fill an ArrayList of a given type. ( give example )

Modularity Section

write a method and its calling code with proper parm passing, return value and visibility. ( give example )

Inheritance Section

True or False Questions

T / F A super class constructor must execute to completion before any statements in its sub class constructor can be executed.

T / F You do not have to call a super class constructor explicitly. T / F Java allows you to inherit directly from only one class, but you may implement multiple interfaces.

T / F When declaring a class as a super class, you should never declare your fields private; use protected instead.

T / F An interface is often thought of as a form of a very restricted super class.

T / F An interface allows us to guarantee that any class that implements it will have the behaviors specified by the interface. It is a contract.

T / F A sub class is not required to override any methods it inherits from its super class.

T / F Instance fields should be initialized in the constructor(s) of the class they were declared in if at all possible.

T / F The two benefits of inheritance are code re-use and polymorphic behavior.
