8.24 lab: warm up: drawing a right triangle this program will output a right triangle based on user specified height triangle_height and symbol triangle_char. (1) the given program outputs a fixed-height triangle using a * character. modify the given program to output a right triangle that instead uses the user-specified triangle_char character. (1 pt) (2) modify the program to use a loop to output a right triangle of height triangle_height. the first line will have one user-specified character, such as % or *. each subsequent line will have one additional user-specified character until the number in the triangle's base reaches triangle_height. output a space after each user-specified character, including a line's last user-specified character. (2 pts) example output for triangle_char = % and triangle_height = 5:

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.
