just some questions I am struggling with, thank you.

Consider the following code: 2 poirnts) ArrayList a = new ArrayList 0; int value; a add(new Integer(6) value a.sizeO: System.out println(value): What happens when this code is compiled? OA compiler error occurs on Line 1 because you cannot instantiate an ArrayList in this way A compiler error occurs on Line 3 because you cannot add a numeric literal int to an ArrayList OA compiler error occurs on Lime 6 because value must be declared as a double. O A compiler error occurs on Line 5 because the parentheses are mismatched This code compiles without errors Multiple Choice 7. Which of the following describes an overridden method? (2 points One of several methods in a class with the same name but different parameter lists One of several methods in a class with the same name but different return values () A method in a subclass with the same method heading as a method in a parent class Any method that invokes superO. A method that contains a call to itself Multiple Choice The process of determining which method in a class hierarchy should execute is known as: f2fonts) nheritance. polymorphism is-a has-a parent class Consider the following code: 2 poirnts) ArrayList a = new ArrayList 0; int value; a add(new Integer(6) value a.sizeO: System.out println(value): What happens when this code is compiled?
