Consider the following partial class declarations for the Triangle and IsoscelesTriangle classes:public class Triangle{private int side1, side2, side3;public Triangle (int a, int b, int c){side1 = a;side2 = b;side3 = c;}// other code not shown}public class IsoscelesTriangle extends Triangle{public IsoscelesTriangle(int s1, int s2){< missing code >}// other code not shown}What code should replace < missing code >?super();super(s1, s2);super(s1, s1, s2);super(int s1, int s2);super(side1, side2, side3);

In the context of the box model, what is the difference between a margin and a padding? a. a padding lies outside a box border, while a margin lies inside it. b. a padding lies inside a box border, while a margin lies outside it. c. a padding can be adjusted independently, while a margin depends on the size of its box. d. a padding depends on the size of its box, while a margin can be adjusted independently.

File account. java (see previous exercise) contains a definition for a simple bank account class with methods to withdraw, deposit, get the balance and account number, and return a string representation. note that the constructor for this class creates a random account number. save this class to your directory and study it to see how it works. then write the following additional code: 1. suppose the bank wants to keep track of how many accounts exist. a. declare a private static integer variable numaccounts to hold this value. like all instance and static variables, it will be initialized (to 0, since it’s an int) automatically. b. add code to the constructor to increment this variable every time an account is created. c. add a static method getnumaccounts that returns the total number of accounts. think about why this method should be static - its information is not related to any particular account. d. file testaccounts1.java contains a simple program that creates the specified number of bank accounts then uses the getnumaccounts method to find how many accounts were created. save it to your directory, then use it to test your modified account class.
