Given the code fragment:
Which code fragment at line 10 prints Welcome 100? A.
B.
C.
D.
This is an interactive task on the real exam — a drag-and-drop, hotspot or ordering question. There is nothing to select here, so the answer is shown below for reference.
Answer: See figure below
The answer is letter B, it's a simple question, just be careful with the wording of the question because it can confuse, I read it fast the first time and almost marked the wrong one.

Given these requirements: ✑ Bus and Boat are Vehicle type classes. ✑ The start() and stop() methods perform common operations across the Vehicle class type. ✑ The ride() method performs a unique operations for each type of Vehicle. Which set of actions meets the requirements with optimized code?
Answer: A
both A and D are correct. in A, we define an abstract class with concrete methods for start() and stop(), and an abstract ride(). in B, we define default start() and stop(), and ride() we keep it abstract. meaning in both approaches we are defining a common operation, and require an overridden version for ride() for the code to work. the only difference is if we want to extend another class other than Vehicle, then we need option D, however with the requirements we have here, both options works fine.

Given:
What is the result?
Answer: D
The answer is the letter D and I tested it (Code below:). An object can be a variable, as it is not primitive, if we call it without assigning values it will have the value null as default, the double has the default value of 0.0 if we don't assign a value, so when passing the println command with the parameters it returns null:0.0 class Cart { Product p; double totalAmount; } class Product { String name; Double price; } public class Test { public static void main (String[] args) { Cart c = new Cart(); System.out.println(c.p + ":" + c.totalAmount); } }

Given:
What is the result?
Answer: A
The answer is the letter A. In the first line where the printing occurs, notice that we did not instantiate the value of "objBook.pages" and "obj.count", as they are int, the default value of this type of variable is 0, so we have already eliminated answers B and D. even passing the "obj.count" in the "method" method, its value does not change because it is an instantiation variable in the App class and not its value remains 0 and it is in the second "println" in the second place, and the only answer that has "0:0" in the first line and "0" in the second place of the second line is the letter A.

Given:
Which two code fragments can be inserted at line n1? (Choose two.)
Answer: AC
The correct answer is AC, I will explain: B -> You can't put a for loop outside the main method D -> This one is very wrong, you can only declare the package in the first line of code E -> This one is as wrong as the letter D, you can only import one package before instantiating the class and if you have a package declared, the declaration can only be made between it and the class declaration, anything outside of that is wrong

Examine the content of App.java:
Which is true?
Answer: C
I really didn't understand the purpose of the question, the same question which of the alternatives is true, but the letters A, C and D are correct and I still tested it just in case. Answer B is the only one that is wrong because to use the app class inside Test you need to do the import because they are in different packages... Now if the question refers to which answer fits the context of the utterance, it would mark answer C. NOTE: Following this logic, for the sake of conscience, I would mark the one that has more to do with the context, because it would be "the most correct".
