IMPORTANT: This is a continuation of the previous part of the project and assumes that you are starting with code that fulfills all requirements from that part of the project.
Modify the your code from the previous part of the project to make it modular.
In addition to the main method, your code must include the following static methods:
Method 1 - displayTitle
A method that creates a String object in memory to hold the text “Computer Hardware Graphics Quality Recommendation Tool” and displays it
Method 2 – getResolutionString
A method that accepts an integer value (1, 2, 3, or 4) that denotes the monitor resolution. The method should return the appropriate String representation of the monitor resolution. For example, if the method is passed an integer value of 1, it should return a String with a value of “1280 x 720”. (See Step 4 of Project 1)
Method 3 – getMultiplierValue
A method that accepts an integer value (1, 2, 3, or 4) that denotes the monitor resolution and…
Design and implement an application that presents three buttons and a label to the user.
The buttons should be labeled Increment, Decrement, and Randomize.
Display a numeric value (initially 50) using the label.
Each time the Increment button is pushed, increment the value displayed.
Likewise, each time the Decrement button is pushed, decrement the value displayed.
When the Randomize button is pushed, the number displayed should be randomized between 1 and 100,
inclusive.
Java Program - GUI Number Guessing
Look at the code, notice that the actionPerformed method is not complete. It just contains code that will print to the console when buttons are pressed. Make the following modifications to the code.
When the Higher button is pressed invoke this.guesser.higher(), and then put the new guess into the this.guessField
When the Lower button is pressed invoke this.guesser.lower() and then put the new guess into the this.guessField
When the Reset button is pressed, invoke this.guesser.reset() and then put the new guess into the ghis.guessField
When the Correct button is pressed, exit the app using System.exit(0).
Wrap the invocation of lower() and higher() in try catch blocks that catch NumberGuesserIllegalStateExceptions. Show a JOptionPane that alerts the user that you are onto their schemes.
Change the guessing algorithm from random-guess to binary search. You can do this by changing the object created for the guesser to a plain old NumberGuesser. It…

The three picture boxes, each containing a flag, are on top of one another, but only one should be visible at a time. For each picture box: Be sure to add the image as a local resource. Set the Size property to 100, 50 Click the Size Mode list arrow, then click StretchImage in the list.

The below form will represent the main form from which the user will navigate to the other forms. Meaning each button should be linked to the appropriate form. E.g. If button Manage Addresses is clicked the form managed addresses should be displayed. The Exit button should successfully terminate the program. Create a void method for each button and name them as follow: LinkToAddresses (), LinkToCustomers (), LinkToDrivers (), LinkToStatus (), and LinkToFreight (). The methods should be called under the appropriate button. For the exit button create a void method named AppExit () this should terminate the program.arrow_forward

Question 11 options: A Visual C# project can have multiple forms. Every form in a Visual C# project has a class. If a Visual C# project has a form named Form1, then the project cannot have a class named Form1. When you create event handlers for a specific form's controls, you write them as methods in that form's class.arrow_forward3. Miles Per Gallon Calculator In Python, write a GUI program that calculates a car’s gas mileage. The program’s window should have Entry widgets that let the user enter the number of gallons of gas the car holds, and the number of miles it can be driven on a full tank. When a Calculate MPG button is clicked, the program should display the number of miles that the car may be driven per gallon of gas. Use the following formula to calculate miles-per-gallon: MPG=miles/gallonsarrow_forward
