Show the output of running the class test in the following code lines:
interface a { }
class c { }
class b extends d implements a { }
public class test {
public static void main(string args) {
b b = new b();
if (b instanceof a)
system. out. println("b is an instance of a");
if (b instanceof c)
system. out. println("b is an instance of c");
}
}
class d extends c { }
a. nothing.
b. b is an instance of a.
c. b is an instance of c.
d. b is an instance of a followed by b is an instance of c.

Simon says is a memory game where "simon" outputs a sequence of 10 characters (r, g, b, y) and the user must repeat the sequence. create a for loop that compares the two strings starting from index 0. for each match, add one point to userscore. upon a mismatch, exit the loop using a break statement. assume simonpattern and userpattern are always the same length. ex: the following patterns yield a userscore of 4: simonpattern: rrgbryybgy userpattern: rrgbbrybgy

Which of the following statements is false? a. a class can directly inherit from class object. b. if the class you're inheriting from declares instance variables as private, the inherited class can access those instance variables directly. c. a class's instance variables are normally declared private to enforce good software engineering. d. it's often much more efficient to create a class by inheriting from a similar class than to create the class by writing every line of code the new class requires.
