Modify the above code to use the alternative method for multithreading (i.e., implementing the Runnable interface). Name your main class RunnableHelloBye and your subsidiary classes Hello and Goodbye respectively. The fi rst should display the message ‘Hello!’ ten times (with a random delay of 0–2 s between consecutive displays), while the second should do the same with the message ‘Goodbye!’. Note that it will NOT be the main class that implements the Runnable interface, but each of the two subsidiary classes.
I can't instantiate this template class in C++. The C++ classes are below. What am I doing wrong?

The Java Programming class has two types – remote and in-person. For remote students, the weighted score comprises of midterm, final, assignments and discussion. The weights for each are 30%, 30%, 30% and 10% respectively. For in-person students, the weighted score comprises of midterm, final and assignments. The weights for each are 30%, 30% and 40%. Write a generic class Students.java which has a constructor that takes three parameters – id, name, and type. Type will represent if the student is ‘remote’ or ‘in-person’. A toString() method in this class will display these details for any student. A generic method score() will be part of this class and it will be implemented by inherited classes. Write accessors and mutators for all data points. Write two classes RemoteStudents.java and InPersonStudents.java that inherits from Student class. Show the use of constructor from parent class (mind you, RemoteStudents have one additional parameter – discussion). Implement the abstract method…
Develop a java program to define an Symbol table class so that each symbol is associated with a numeric value. The two main methods are set() and get(): void set(String sym, int value); int get(String sym); The set() method associates the int value with the symbol sym, while the get() method performs the complement of retrieving the int value previously associated Define appropriate exceptions so that clients of the Symbol table may respond to conditions appropriately. For example, when they retrieve the value of a nonexist clients can either stop execution and display an error message or use a default value of 0 Symbol Numeric Value
IN JAVA intends to auto generate test cases for a function foo that has k integers as input arguments, i.e., foo(int n1, int n2, …, int nk). Each argument belongs to a different equivalence class, which are stored in a downloadable Eq.txt file. The content is shown below and may be modified to handle more inputs and equivalence classes. 1, 15; 16, 30 1, 10; 11, 20; 21, 30 1, 5; 6, 10; 11, 15 1, 3; 4, 6; 7, 9; 10, 12 1, 12; 13, 24 For this file, the nth row describes the nth input. Take the second row for example. There are five input arguments. The data 1, 10; 11, 20; 21, 30 indicates that argument n2 has three equivalence classes separated by the semi-colons. Develop an internal method “private int check(int val)” that returns the equivalence class the val is in. The result of check(val = 3) for n2 will be 1 and check(val = 25) for n2 will be 3. Regarding the function foo, it computes the sum of the returned values by the check function for all input arguments. Follow the contents…
I need to know how to do this in python: The base class Pet has attributes name and age. The derived class Dog inherits attributes from the base class Pet class and includes a breed attribute. Complete the program to: Create a generic pet, and print the pet's information using print_info(). Create a Dog pet, use print_info() to print the dog's information, and add a statement to print the dog's breed attribute. Ex: If the input is: Dobby 2 Kreacher 3 German Schnauzer the output is: Pet Information: Name: Dobby Age: 2 Pet Information: Name: Kreacher Age: 3 Breed: German Schnauzer
