A variable like userNum can store a value like an integer. Extend the given program to print userNum values as indicated.(1) Out

dimulka [17.4K]

Answer:

The program in Java is as follows:

import java.util.*;

public class Main{

public static void main(String[] args) {

int userNum;

Scanner input = new Scanner(System.in);

System.out.print("Enter integer: ");

userNum = input.nextInt();

System.out.println("You entered "+userNum);

System.out.println(userNum+" squared is "+(userNum*userNum));

System.out.println(userNum+" cubed is "+(userNum*userNum*userNum));

int userNum2;

System.out.print("Enter another integer: ");

userNum2 = input.nextInt();

int sum= userNum + userNum2; int product = userNum2 * userNum;

System.out.println(userNum+" + "+userNum2+" = "+sum);

System.out.println(userNum+" * "+userNum2+" = "+product); } }

Explanation:

This declares userNum

int userNum;

Scanner input = new Scanner(System.in);

This prompts the user for input

System.out.print("Enter integer: ");

This gets user input from the user

userNum = input.nextInt();

Number (1) is implemented here

System.out.println("You entered "+userNum);

Number (2) is implemented here

System.out.println(userNum+" squared is "+(userNum*userNum));

System.out.println(userNum+" cubed is "+(userNum*userNum*userNum));

This declares another variable userNum2

int userNum2;

This prompts the user for another input

System.out.print("Enter another integer: ");

This gets user input from the user

userNum2 = input.nextInt();

This calculates the sum and the product

int sum= userNum + userNum2; int product = userNum2 * userNum;

Number (3) is implemented here

System.out.println(userNum+" + "+userNum2+" = "+sum);

System.out.println(userNum+" * "+userNum2+" = "+product);

Please write a complete program to calculate monthly payment given

jasenka [17]

Explanation:

Code with comments:

#include <stdio.h>

#include <math.h>

/* math library is required to use pow() function

First we need to create a function to calculate the Monthly Payment

It would take three inputs Rate, Years, and Principle amount

Then we converted the Rate and Months according to problem statement

pow() function is used to find (1+R)^M

Then finaly this function returns the value of Monthly Payment */

float MonthlyPay(float R, int M, int P)

{

R=R/1200;

M=M*12;

float po=pow((1+R),M);

float PayM=(R+(R/(po-1)))*P;

return PayM;

}

/* In the main() function we get 3 inputs from the user Years, Rate and Principle amount

then we call the MonthlyPay function and pass it 3 inputs that we got from the user

then we calculated the total Payment by multiplying the Monthly Pay and total number of months

then we calculated the interest Amount by subtracting the Principle Amount from total Pay

Testing is performed and output result is given at the end and also attached in the image */

int main(void)

{

float Rate;

int Year, Amount;

printf("Enter Years: ");

scanf("%d",&Year);

printf("Enter Rate: ");

scanf("%f",&Rate);

printf("Enter Principle Amount: ");

scanf("%d",&Amount);

float Pay = MonthlyPay(Rate, Year, Amount);

printf ("Monthly Payment is: %f \n", Pay);

float totalPay=Pay*Year*12;

printf ("Total Payment is: %f \n", totalPay);

float interest=totalPay-Amount;

printf ("Interest Expense is: %f \n", interest);

return 0;

}

Output:

Enter Years: 5

Enter Rate: 7

Enter Principle Amount: 12200

Monthly Payment is: 241.572767

Total Payment is: 14494.367188

Interest Expense is: 2294.367188

Create a class named Horse that contains the following data fields: name - of type String color - of type String birthYear - of

kozerog [31]

Answer:

The program to this question can be given as:

Program:

class Horse //define class Horse

{

private String name; //define variables.

private String color;

private int birthYear;

//define set method.

public void setName(String name)

{

this.name = name; //set value of name.

}

public void setColor(String color)

{

this.color = color; //set value of color.

}

public void setBirthYear(int birthYear)

{

this.birthYear = birthYear; //set value of birthYear

}

//define get method.

public String getName()

{

return name; //return name.

}

public String getColor()

{

return color; //return color.

}

public int getBirthYear()

{

return birthYear; //return birthYear.

}

class RaceHorse extends Horse //define class RaceHorse

{

private String raceNum; //define variable.

public void setRace(String raceNum) //define set method.

{

this.raceNum=raceNum; //set value of raceNum.

}

public String getRace()

{

return raceNum; //return raceNum

}

public class Main //define main class.

{

public static void main(String[] args) //define main method.

{

Horse ob= new Horse(); //creating class objects.

RaceHorse ob1 = new RaceHorse();

ob.setName("XXX"); //calling function

ob.setColor("BLACK");

ob.setBirthYear(2008);

ob1.setRace("Five hundred meter");

//print return values.

System.out.println("The name of the horse is " + ob.getName()+"." +"\n"+

"The horse's color is " + ob.getColor()+"."+"\n"+ "It was born in " + ob.getBirthYear() +

"."+"\n"+ ob.getName()+" has taken part in " + ob1.getRace() + " races.");

}

Output:

The name of the horse is XXX.

The horse's color is BLACK.

It was born in 2008.

XXX has taken part in Five hundred meter races.

Explanation:

In the above program firstly we declare the class that is Horse in this class we define a variable that name is already given in the question which are name, color, and birthYear. In these variables are name and color datatype is string and the birthYear datatype is an integer because it stores the number. Then we use the get and set function in the get function we return all variable value. and in the set function, we set the values of the variable by this keyword. Then we declare another class that is RaceHorse this class inherit Horse class. In the RaceHorse class, we define a variable that is raceNum that's data type is a string in this class we also used the get and set function. Then we declare the main class in the main class we define the main method in the main method we create the above class object and call the set and get function and print the values of the function.
