yawa3891 [41]

Answer:

The following program are written in JAVA Programming Language.

//inherit the Calculator class

public class CalculatorWithMemory extends Calculator {

private double memory = 0.0; //initialize double type variable

public void save() { //define function

memory = accumulator;

}

public void recall() { //define function

accumulator = memory;

}

public void clearMemory() { //define function

memory = 0; //initialize the value

}

public double getMemory() {

return memory; // return the value in "memory" variable

}

Explanation:

Here, we inherit the property of the "Calculator" class.

Then, we define the private double type variable "memory" and assign value 0.0.

Then we set the function "save()" inside it we assign the value of "memory" in "accumulator" and close the function.

Then, we define the function "recall()" inside it we assign the value of "accumulator" in "memory" and close the function.

Then we set the function "clearMemory()" inside it we assign "memory" to 0.

After all, we set the double type function "getMemory()" inside we return the value of the "memory".

One lap around a standard high-school running track is exactly 0.25 miles. Write a program that takes a number of miles as input

salantis [7]

Answer:

import java.util.Scanner;

public class Miles {

public static void main(String[] args) {

//initialization

double Number_Miles;

//print the message

System.out.print("Enter the number of miles: ");

Scanner scn1 = new Scanner(System.in);

Number_Miles = scn1.nextDouble(); //read the input from user

//calculate the laps

double yourValue = Number_Miles/0.25;

//display the output on the screen

System.out.printf("%.2f", yourValue);

}

Explanation:

First import the library Scanner than create the class and define the main function. In the main function, declare the variables.

print the message on the screen and then store the value enter by the user into the variable.

Scanner is a class that is used for reading the output. So, we make the object of the class Scanner and then object call the function nextDouble() which reads the input and store in the variable.

After that, calculate the number of laps by dividing the number of miles with the given one lap running track value (0.25 miles).

$Number\,of\,laps = \frac{Number\,of\,miles}{0.25}$
