also need help Write a second constructor that takes a String array of pages as input and sets the String array instance variable equal to the input. Continue to default the page number to zero. Part 2: Write a getter and a setter method for the current page number variable. The setter should check to make sure that the input is a valid page number and only update the variable if the new value is valid. Part 3: Write a getCurrentPage method that returns the String of the current page indexed by current_p

The first version of Abby’s Eggs worked but was a bit cumbersome. I.e. you couldn’t edit a single parameter, you had to always re-enter all of them. Store the parameters (number of chickens, eggs laid per day, etc.,) in static fields of the class. Have separate methods for updating the parameters. Use a switch statement to take menu selections for updating parameters or outputting results. If the menu choice is 0, the program should terminate, invalid inputs should be ignored and any prompt repeated. Before displaying updated menu, "clear the screen" I got most of the code working, but I can't find a way to clear the sceen before displaying the updated menu. I tried using "System.out.print("033円[H033円[2J"); System.out.flush();", but it is not working. I am using the Apache NetBeans IDE.

Description is " A MathVector object will be passed to your method. Return its contents as a String. If you look in the file MathVector.java you'll see there is a way to output the contents of a MathVector object as a String. This makes it useful for displaying to the user. You might have noticed that there's an @override term there. That's because many objects already have a "toString()" method associated with them... because Java was designed to include them by default. Here, the override tells Java "I know, I know. You already have a toString() that you'd assign here. But it's not good enough. Here's a better one for this particular kind of object." It's a little bit like saying "Most humans have two legs. So, by default, I'll give everyone two legs. But sometimes we override that and give no legs, or just one leg to a person. And sometimes we give them four so that they can be a centaur!" To use this in a println() method, just name your object. The toString()...

For this lab task, you will work with classes and objects. Create a class named text that works similar to the built-in string class. You will need to define a constructor that can be used to initialize objects of this new class with some literal text. Next, define three methods: to_upper() that will convert all characters to uppercase, reverse() that will reverse the text and length() that will return the length of the text. After you have completed this part, copy the following mainfunction to your code and check if the implementation is correct. int main() { text sample = "This is a sample text"; cout << sample.to_upper(); // This should display "THIS IS A SAMPLE TEXT" cout << endl;cout << sample.reverse(); // This should display "txet elpmas a si sihT"cout << endl; cout << sample.length(); // This should display 21 }

Write a modified Button class that creates circular buttons. Call your class CButton and implement the exact same methods that are in the existing Button class. Your constructor should take the center of the button and its radius as normal parameters. Place your class in a module called cbutton . py. Test your class by modifying roller . py to use your buttons.

using eclipse part 1 Create a different package session5a. Create a class SquareDemo. Create an instance of Square in the main() method with sideLength set to 10. along with output screenshot for this part. Part 2 Create 12 Square instances in SquareDemo class with random size (1-100) and print out: If divisible by 2, print out side length If divisible by 3, print out area If divisible by 6, print out side length and area Otherwise, print out "Side length and area are hidden" along with output screenshot for this part.

In netbeans, Write a method named findLastTwoLetters that is passed a String parameter and that prints the last two letters of the string. For example, "ta" is returned if the parameter is "Roberta". You are guaranteed as a precondition that the parameter will have a length greater than 1. This method can be completed using substring().

Currently, there are two draw rectangle methods in the DoodleController class. Since two different turtles need to draw a rectangle, create a draw rectangle method in the DoodleTurtle class that will take the width and height of the rectangle as parameters and draw a rectangle of the specified size. The size will be the number of steps by the turtle. With the new method introduced, the calls to drawRectangleWithLittleTurtle and drawRectangleWithBigTurtle can be replaced with a call to the turtle’s drawRectangle method passing in the desired size of the rectangle. Refactor the DoodleController accordingly. Note: When you are done with the refactoring the drawRectangleWithLittleTurtle and drawRectangleWithBigTurtle method in the DoodleController need to be deleted. After this refactoring, do not move on until you verify the program works as it did before.
