Java Program Method To Calculate Distance

Feb 20, 2015

Write method distance, which calculates the distance between two points (x1, y1) and (x2, y2). All numbers and returned values should be of type double. Incorporate this method into an program that enable the user to enter the coordinates of the points, then calculate and display the distance by calling the method –distance.

I've tried numerous times to make it work and I'm on the right path, however I'm missing some things in the code to make my results look like this later on, which I've attached onto this post.

Loop That Calculate Distance Traveled - Why Java Not Printing Method Results

Apr 13, 2014

I am trying to write a loop that calculates the distance traveled (distance = speed * time). It should use the loop to calc how far the vehicle traveled for each hour of time. My program asks for hours and then mph but its not calculating time * speed. Here is my code.

public static void main(String[] args) {
 Scanner input = new Scanner(System.in);
System.out.println("Enter Hours Traveled ");
int hoursTraveled = input.nextInt();
System.out.println("Enter MPH ");
int mph = input.nextInt();

Modify DrawShape Method To Calculate Distance From Starting Point

Mar 13, 2015

I need to modify the drawShape method to calculate the distance from the starting point (the diameter) of any shape regardless of how many sides I give it, but I have absolutely no clue where to begin with this. The ultimate goal of the program is to calculate the value of pi using the shape that is drawn.

Java Code:

public class PiTurtle extends Turtle
{
private double mySize;
private int mySides;
private double diameter = 0;

Method Parameters - Two Fields Of Type Double / Calculate Distance To Another Point

Oct 18, 2014

I've just been having a go at an exercise where I have to create and use a class called Point, with two fields of type double. I have to create some methods for it, one of which is a distanceTo(Point) method, that calculates the distance to another point. I've tried to keep the distanceTo(Point) method short so have created some other methods to use within the method. My question is about the getDistance() method that I've made. As you can see below, I've given it two parameters, which are references to values within two Point objects (this.x and otherPoint.x).

double distanceTo(Point otherPoint) {
double distanceX = getDistance(this.x, otherPoint.x);
double distanceY = getDistance(this.y, otherPoint.y);
return calculateLength(distanceX, distanceY);
}

Java Program - Distance Traveled (Formatting And Decimal Place)

Apr 10, 2014

I'm having trouble formatting my output and issues with the decimal places. Here's my code:

import java.util.Scanner;
import java.text.DecimalFormat; // Imports DecimalFormat class for one way to round
 public class lab3 {
public static void main(String[] args) {
String heading1 = "Hour", heading2 = "Distance Traveled";
int timeElapsed, hour, speed;

[Code] ....

And here's my output (Click on the image since it's pretty small):

javaIssues.png

Issue:
1) The Hours 2 and 3 aren't aligned to 1.
2) The 80 and 120 in Distance Traveled have 6 decimal places when it should not have decimals.

Calculate Distance Between Two Coordinates And Determine How Much Of Which Axis To Increment / Decrement

Feb 1, 2015

Basically I'm looking for a way to make one object follow another. For example, if I move object A to one area of the screen I want object B to to move to object A's location but I also want object B to move at a fixed speed (movement variable). How do I go about doing this?

Both the x and y coordinates of object B would need to know the coordinates of object A to calculate the distance between the two and to determine how much of which axis to increment/decrement (if that makes sense?) with the inclusion of the speed variable. In other words I'm just trying to create a homing object.

Calculate Distance Between Two Points - All Numbers And Return Values Should Be Of Type Double

Jul 8, 2014

Write method distance to calculate the distance between two points (x1, y1) and (x2, y2). All numbers and return values should be of type double. Incorporate this method into an application that enables the user to enter the coordinates of the points.

Hints:

- The distance between two points can be calculated by taking the square root of

( x2 - x1 )2 + ( y2 - y1 )2

- Use Math class methods to compute the distance.

- Your output should appear as follows:

Type the end-of-file indicator to terminate

On UNIX/Linux/Mac OS X type <ctrl> d then press Enter

On Windows type <ctrl> z then press Enter

Or Enter X1: 1

Enter Y1: 1

Enter X2: 4

Enter Y2: 5

Distance is 5.000000

Type the end-of-file indicator to terminate

On UNIX/Linux/Mac OS X type <ctrl> d then press Enter

On Windows type <ctrl> z then press Enter

Or Enter X1: ^Z

Write A Program That Will Call A Method To Calculate Function

Dec 3, 2014

I have understood my programming class up to this point and now I have been given a lab that I can't figure out for the life of me. Here what I have to do: Write a program that will call a method (called f) to calculate the following function" f(x)=(x^2)-16...this is what the output should be:

x f(x)
1 -15
2 -12
3 -7
4 0
5 9
6 20
7 33
8 48
9 65
10 84

I guess it also has to print this output in a table even though my professor never mentioned it. Usually

public class Lab12 {
public static int f(int x)
{
return x*x-16;

[code]....

Java Program To Calculate Diameter?

May 6, 2014

Assume the tanker is a cylinder of length 19.35 feet and volume 1320 gallons. What is the diameter in feet of the tanker truck? To solve this problem, write a Java program to calculate the diameter. For full credit, your Java application must follow these specifications.

1. The program must interactively input the capacity of the tanker in gallons and its length in feet. This should be done in the main method of your Tester class.

2. The input data should then be used to construct a TankerTruck object. You will need to write the TankerTruck class.

3. A TankerTruck method should be used by main to calculate the resulting diameter of the truck in feet.

4. Your program should use the standard Java constant for the math constant PI.

5. The output should be displayed using fixed-point notation, rounding to one decimal place of precision

Trying To Calculate Fine Using Method Calls

Jul 3, 2014

I am trying to calculate a fine in a PoliceOfficer object with method calls to a ParkedCar and ParkingMeter object. The word problem is:

The fine is $25 for the first hour or part of it and $20 for every additional hour of part of it.

My code is:

public class PoliceOfficer
public static final int PARKING_FINE1 = 25;
public static final int PARKING_FINE2 = 20;
public static final int NUMBER_OF_MINUTES_OVER_PARKED = 60;
public double calculateFine(){

obviously the fine is not calculated correctly but I'm not sure how to proceed from here...

Create A Program That Will Calculate Different Tax Brackets

Oct 3, 2014

I have spent the past 12 hours on it and have gotten no where. I need to create a program that will calculate different tax brackets. I have tried all combinations I can think of and can't get it to work!!! I am literally about to go insane! I need the program to calculate tax will be 1% for anything up to $50000. If the tax is over $50000, you keep that 1% of $50000 and then add the remaining. So for an income in the second range, it would be 1% of $50000, and then 2% of (income - $50000). This then continues for each range.

The problem I'm having is getting it to display the correct interest rates. I am not asking for you to write it for me. I want to learn. But at this point I have exhausted all resources available to me.

import java.util.Scanner;
public class Project3taxinfo {
public static void main(String[] args) {
final double RATE1 = 0.01; //1% tax on the first $50,000
final double RATE2 = 0.02; //2% tax on the amount over $50,000 up to $75,000
final double RATE3 = 0.03; //3% tax on the amount over $75,000 up to $100,000
final double RATE4 = 0.04; //4% tax on the amount over $100,000 up to $250,000
final double RATE5 = 0.05; //5% tax on the amount over $250,000 up to $500,000
final double RATE6 = 0.06; //6% tax on the amount over $500,000
