public class A { public static void methodl () { } } public class B { public static void method1 () { } System.out.println("B1"); } public class C { } System.out.println("C2"); public static void methodl () { Statement System.out.println("B1"); } And assuming the following objects have been defined: A a = new A(); B b = new B(); B other2 = new C(); In the table below, indicate in the right-hand column the output produced by the statement in the left-hand column. If the statement causes an error, fill in the right-hand column with either the phrase "compiler error" or "runtime error" to indicate when the error would be detected. Output a.methodl (); a.method2 (); b.methodl (); b.method2 (); other2.methodl (); other2.method2 ();

Correct and detailed answer will be Upvoted else downvoted. Thank you!

Partial Question 3 Consider: class A { } public void doA() { } class B extends A { } public void doB () { } Which of the following are allowed? B x = new B(); x.doB(); A x = new A(); x.doA(); A x = new A(); x.doB(); B x = new B(); x.doA();

Find the error(s) in the following class definition: public class TestClass private int value1; private int value2; public void TestClass(int num1, int num2) { value1= num1; value2 = num2; }

Incorrect Question 4 Consider public class Species { } // fields private String name; private int population; private double growthRate; // constructor public Species () { } name = "No Name Yet"; population = 0; growthRate = 33.3; Which of the following is the best setter method for the population instance variable? public boolean setPopulation(int newPopulation) { } if (newPopulation>= 0) { } population = newPopulation; return false; } return true; public public void setPopulation (int newPopulation) if (newPopulation>= 0) { } population newPopulation; public void setPopulation (int newPopulation) { population } = newPopulation;

Single responsibility (from our SOLID principles) means that classes must implement only ONE method. In other words, a class defining multiple methods breaks the SOLID guidelines A) True B) False

class IndexItem { public: virtual int count() = 0; virtual void display()= 0; };class Book : public IndexItem { private: string title; string author; public: Book(string title, string author): title(title), author(author){} virtual int count(){ return 1; } virtual void display(){ /* YOU DO NOT NEED TO IMPLEMENT THIS FUNCTION */ } };class Category: public IndexItem { private: /* fill in the private member variables for the Category class below */ ? int count; public: Category(string name, string code): name(name), code(code){} /* Implement the count function below. Consider the use of the function as depicted in main() */ ? /* Implement the add function which fills the category with contents below.
