Explanation of Solution
Naming conventions:
It is the set of rules used for choosing the character sequence of identifier name. The naming conventions denote variables, methods, classes, and constants.
Naming conventions for method name:
- Naming conventions for method are:
- If the name of the method consists of multiple words, join them into one.
- Make the first letter as lowercase and capitalize the first letter of each sub word.
- Examples: “numberOfPassmarks”, “calculateMarks()”, etc.
| Method Identifiers | a | b | c | ||
| Legal | Conventional | Legal | Unconventional | Illegal | |
| associationRules() | Yes | Yes | |||
| void() | Yes, the method identifier is illegal, since “void” is keyword | ||||

Create a Java program and name your file: FIRSTNAME. java (for example, lohn.java).
Work on the following:
Create three interfaces with the names "InterfaceOne," "IrnterfaceTwo," and "Interfacelhree"
In the first interface, declare a method (signature only) with a name "updateGear()."
In the second interface, dedare a method (signature only) with a name "accelerate()."
In the third interface, dedare a method (signature only) with a name "pusherake()."
Create two classes Car and Truck that implement these three interfaces at one time. Define a
new method "currentSpeed()" in both the classes to find the current speed after the brake.
• Define all the three methods inside each class. The data to these methods will be provided
during the object creation.
Invoke the two objects with a name c1 of class Car and t1 of class Truck.
• After creating the objects, call all the three methods defined above in both the classes.
Pass any of the…

This process should contain methods as follows: main(): This method should: 1. Call makeFrame() to get the inputs and create a Frame object. 2. Call calcCost() to determine the cost of the picture. 3. Display the cost of the picture along with the attribute values. 4. Ask the user if he/she wants another picture. 5. If the answer is No, display the total cost of the picture 6. If the answer is Yes, implement steps 1 and 2 again (without a loop), then display: ● the number of frames created (through a variable) • total cost of the picture(s), and • average picture cost. 6. The program should then end. Class methods: makeFrame() A function to prompt the user for inputs and accept the four (4) input values needed to create an instance of a Frame.

- Open the Palace Solution.sln file contained in the VB2017\Chap10\Palace Solution folder. Use Windows to copy the Rectangle.vb file from the VB2017\Chap10 folder to the Palace Project folder. Then, use the Add Existing Item option on the Project menu to add the file to the project. Modify the Rectangle class to use Double variables rather than Integer variables. Change the name of the GetArea method to GetAreaSqFt. Add another method to the class. Use Get AreaSqYds as the method’s name. The method should calculate and return the area of a rectangle in square yards. The application’s Calculate button should calculate and display the number of square yards of carpeting needed to carpet a rectangular floor. Code the btnCalc_Click procedure. Display the number of yards with one decimal place. Save the solution and then start and test the application.arrow_forwardWhich of the following statements is false? a.
