In a class method (a method declared as static) can instance variables from the same class be used?
Choose one of the options:
True
False
Step by step
Solved in 2 steps
- ANSWER IN JAVA Create a class called Date that includes three instance variables-a month (type int), a day (type int) and a year (type int). Provide a constructor that initializes the three instance variables and assumes that the values provided are correct. Provide a set and a get method for each instance variable. Provide a method displayDate that displays the month, day and year separated by forward slashes (/). Add a main method to the class that demonstrates class Date's capabilities.In Java: Create a class called Date that includes three instance variables-a month (type int), a day (type int) and a year (type int).

Then change itsbrand to "Sharp" and switch it on. print the status of the 2 machines. declare and create an array that can hold up to 3 machines fill the array with suitable data print how many machines of brand "Dell" declare and create an ArrayList of machines fill the list with suitable data print how many machines are On.
- 30. True or False: The parameterized constructors of Java does not accept any parameters instead, using these constructors the instance variables of a method will be initialized with fixed values for all objects. False True Give an explanation for the answer. Thank youWrite a java class named Account which contains: private data field named number of type int private data field named balance of type double no argument constructor An argument constructor to create Account object with specified number and balance. A method toString() that returns number and balance as a String Set and Get Methods for all the data fields(Java) Question 2 Explain the answer step-by-step and include verbal explanation. Thank you! What is the difference between overriding a method and overloading a method? Select the correct option next to each statement, or select both options if the statement is true for both. Both methods have the same name: Overriding / Overloading Both methods have the same signature: Overriding / Overloading Both methods are defined in the same class: Overriding / Overloading
- Python Class and Objects 1. Create a class named "Account" and “Bank” 2. The class “Account” should have a parameter of id - integer type name - string type balance - float type # (Optional) You may add more parameters for your convenience 3. Create a method for “Account” class: checkBalance(self) - this will show the Account's remaining balance or money withdraw(self, amount) - this will withdraw an amount from the Account deposit(self, amount) - this will deposit an amount from the Account # (Optional) You may add more methods like sendMoney() etc.java -- Which declaration of the main method below would allow a class to be started as a standalone program. a. public static void main(String args) b. public static int main(char args[]) c. public static void MAIN(String args[]) d. public static void main(String args[])Static methods within a class are copied into each object created from the class. true or false java
