Question
Write a class RangeInput that allows users to enter a value within a range of values that is provided in the constructor. An example would be a temperature control switch in a car that allows inputs between 60 and 80 degrees Fahrenheit. The input control has "up" and "down" buttons. Provide up and down methods to change the current value. The initial value is the midpoint between the limits. As with the preceding exercises, use Math.min and Math.max to limit the value. Write a sample program that simulates clicks on controls for the passenger and driver seats.
PLEASE USE THE TEMPLATES PROVIDED AND ENSURE THAT IT WORKS WITH THE TEST CLASS
Transcribed Image Text:public class RangeInput{
private int currentValue;
private int highValue;
private int lowValue;
public RangeInput(int high, int low){
// this is the constructor
// your code here
}
public vsoid up(){
// this is a mutator method
// that increases currentValue if allowed
// your code here
// imagine high vlaue is 50 and currentValue is 40
}
public void down (){
// this is a mutator method
// that decreases currentValue if allowed
// your code here
}
public int getCurrentValue (){
// this is an accessor method
// your code here
}
Transcribed Image Text:public class RangeInputTester{
public static void main(String[] args){
RangeInput myInput = new RangeInput (30,20);
System.out.println("current value: " + myInput.getCurrentValue ());
for (int i=0;i<4;i++){
myInput.up();
}
System.out.println("new value:
+ myInput.getCurrentValue());
for (int i=0;i<50;i++){
myInput.down ();
}
System.out.println("last value:
+ myInput.getCurrentValue());

- 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.arrow_forwardCreate a class called SquareTester that will create a Square object. Print out the toString method with the object as your receiver. Print out the perimeter using the getArea method and the object as your receiver. public class SquareTester { public static void main(String{}args) { //create your Square object with any value as your argument //print the toString method //print the area of the square on a new line -ex: "The area is: 64" } }arrow_forwardDraw the UML diagram for the class. Implement the class. Write a test program that creates an Account object with an account ID of 1122, a balance of 20,000,ドル and an annual interest rate of 4.5%. Use the withdraw method to withdraw 2,500,ドル use the deposit method to deposit 3,000,ドル and print the balance, the monthly interest, and the date when this account was created.arrow_forward
- 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 }arrow_forwardWrite the code for the timeTick method in ClockDisplay that displays hours, minutes, and seconds, or even implement the whole class if you wish.arrow_forwardA getPaycheck method that implements the same method in the Employee class. Itcalculates the paycheck amount (m_hours ×ばつ m_hourlyWage) and returns the studentworker’s paycheck as a string in the following format (Note that the three fields areseparated by a hyphen, represented by the minus character. Do NOT add spaces beforeor after each hyphen. There are no commas in the number.):arrow_forward
- 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.arrow_forwardWrite a class RangeInput that allows users to enter a value within a range of values that is provided in the constructor. An example would be a temperature control switch in a car that allows inputs between 60 and 80 degrees Fahrenheit. The input control has "up" and "down" buttons. Provide up and down methods to change the current value. The initial value is the midpoint between the limits. As with the preceding exercises, use Math.min and Math.max to limit the value. Write a sample program that simulates clicks on controls for the passenger and driver seats. Please ensure that it works with the test class provided.arrow_forwardYou are given a Conversion class and need to complete it by adding two static methods. The first method should be called gallonsToPints and take a double gallons and return the number of pints as a double (1 gallon = 8 pints). The second method should be called feetToInches, also taking a double number of feet and returning the number of inches as a double (1 foot = 12 inches). Test your program in the ConversionTester class by printing out two conversions. In javaarrow_forward
- Pythonarrow_forwardAdd a new Java class to your project by right clicking on the src folder in the Project pane and select New > Java Class.Enter Hours as the name for this class, and IntelliJ will add it to the files in the src folder for your project. Remember tocopy and insert the standard heading for the main method as you did for Program 2.Write a program that prompts the user to enter a number of hours, and produces the equivalent number of days as a wholenumber along with the number of hours left over. Assume that a day has exactly 24 hours. The following example showsthe format to use for your output, where the input entered by the user is underlined.Enter the number of hours: 100100 hours is 4 days, plus 4 hours.Define Variables: The number of hours will be a whole number, and we would like to obtain results as whole numbers ofdays and hours, so use the int data type to declare the variables to hold the numbers of hours input, as well as the results(the number of days and number of hours left...arrow_forwardPythonarrow_forward
