Question 382 pts Insert the missing code in the following code fragment. This fragment is intended to initialize an instance variable. public class Vehicle { int numAxles; public Vehicle(int axles) { numAxles = axles; } public Vehicle() { _________ } } Which of the following lines of code will allow the second constructor to call the first constructor? Group of answer choices this. numAxles(0); this(axles); this(0); this(numAxles);
Added by Amanda C.
Step 1
The first constructor `public Vehicle(int axles)` initializes the instance variable `numAxles` with the value passed as an argument. The second constructor `public Vehicle()` is a no-argument constructor that should initialize `numAxles` to a default value. Show more…

ArrayList< Integer > a = new ArrayList< Integer >(); int value; a.add(4); a.add(5); a.add(new Integer(6)); value = a.size(); System.out.println(value); What happens when this code is compiled? A 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 an int to an ArrayList< Integer >. A compiler error occurs on Line 5, because the keyword new is missing when adding an Integer. A compiler error occurs on Line 6, because value must be declared as an Integer. This code compiles without errors.
