This is what i got so far:
Java Code: package assignment7;
public class Exercise3
{
public static void main (String[] args)
{
for (int count =0; count < 4; count++)
{
for (int j=0; j < count+1; j++)

I'm making a program that prints arrows of varying tail length, head width, and displacement.The shape algorithms are working properly, but the displacement isn't working. The first arrow has zero displacement, and the second one is supposed to be bigger and start the print at 10 spaces right and 5 spaces down from the default, but it's not working. I tried changing the displacement settings of the first arrow, and no changes happened, so I know that the positions aren't registering properly in general. How to pass the xAdj and yAdj (displacement) values? I think I have the empty space formula set up, but it's still not running.
Driver: public class Driver { //default values public static final int Arrow_Default_xAdj = 0; public static final int Arrow_Default_yAdj = 0; public static final int Arrow_Default_tail = 5; public static final int Arrow_Default_width = 5;
I am trying to draw at my mouse a certain shape that I have set. I defined some shapes where they extend shape and draw circles and stuff. But when I click on panel it seems the paint doesnt put anything there. Debugger tells me shapes are saved though.
Java 2D Drawing Application. The application will contain the following elements:
a) an Undo button to undo the last shape drawn.
b) a Clear button to clear all shapes from the drawing.
c) a combo box for selecting the shape to draw, a line, oval, or rectangle.
d) a checkbox which specifies if the shape should be filled or unfilled.
e) a checkbox to specify whether to paint using a gradient.
f) two JButtons that each show a JColorChooser dialog to allow the user to choose the first and second color in the gradient.
g) a text field for entering the Stroke width.
h) a text field for entering the Stroke dash length.
I) a checkbox for specifying whether to draw a dashed or solid line.
j) a JPanel on which the shapes are drawn.
k) a status bar JLabel at the bottom of the frame that displays the current location of the mouse on the draw panel.
If the user selects to draw with a gradient, set the Paint on the shape to be a gradient of the two colors chosen by the user. If the user does not chosen to draw with a gradient, the Paint with a solid color of the 1st Color.
Note: When dragging the mouse to create a new shape, the shape should be drawn as the mouse is dragged.
This is my code so far which is correct my only problem is that I have to make it so there doesn't become more than 50 asterisks on a line and I don't know how to do that I know the code is something divided by 50 but I dont understand where I would put it.
so instead of this
************************************************** ******************(pretend it was 100 asterisks) it would be ****************************************(x<50 asterisks or 42)
import java.util.*; public class Graph { private int [] counter; public Graph(int x) { counter=new int[5];
I need to make a loop that prints out a certain number of asterisks, depending on the random number generated (includes 0-24, not including 25). I'm just in basic java programming and am stuck on this task.
These are the directions given to me:
Write a loop to do the following tasks 10 times: -Generate a random number in the range of 0 to 24 and store in an int variable named: score -Write loop to print a bar of asterisks proportional to the value in score :
For example: , if value stored in score is 8, the bar chart should like as follows: (value of score spaced by a tab ( ) and a series of 8 asterisks in one line) 8 ******** //end of the loop
I've tried looking for other questions like this, but this one is a random number, with no input. Yes, I know there are easier ways, but my professor is extremely picky with everything.
This is what I have so far:
public class PA5LoopsA { public static void main(String [] args) { //Declare variables int score; //Generate random number between 0 and 24 score = (int) (Math.random() * 25);
[Code] ....
Clearly, none of my formatting went through...yes, I know how to space everything out!
Overview: Use the Eclipse Java environment to create and test a program using methods that will display a bar graph.
Specifics: This assignment is an extension of the Module 5 activity, the first bar chart (asterisk) display program. You should also make use of the Bar Chart printing program of Chapter 6 (Fig. 6 in the textbook, p. 217).
Your program should use methods to accept input from the keyboard, store it in an array, and use that data to display a bar graph.
Pseudocode for the program might look like the following.
Main declare an array of integers get the number of asterisks in each bar print the bar graph get the number of asterisks in each bar declare a Scanner input object declare an array to fill and return
[code]....
Problem is I cannot get it to display the number of asterisks I enter as input.
So currently I'm trying to learn how to draw a square with asterisks based on the input I give for it's sideLength.
So if I have a Square(5) it should draw a 5x5 looking like this:
***** ***** ***** ***** *****
but then in the main method, it should draw multiple squares of given sizes, so say 5, 6, and 7. Making a square for each of the given numbers. This is what I currently have so far ....
class Square { int sideLength; Square( int size ) { sideLength= size; } int getArea() { return sideLength * sideLength;
I have tried to print array elements using standard print statement. I am getting errors. How to print them. Here is my code:
class arrayEx1{ public static void main(String args[]) { int a[]=new int[3]; //Declaring Single Diomentional Array a[0]=10; a[1]=20; a[2]=30; int total=a[0]+a[1]+a[2]; System.out.println("Values stored in a[0],a[1],a[2]elements are :" + a[0] a[1] a[2]); System.out.println("Total values of a[0],a[1],a[2]elements is :"+ total); } }
if i give comma (,) in between above print stament (print statement 1) stil i am getting errors.
My current calculator (currently available on my site) launches your default webbrowser with the CalculatorHistory file allowing you to print through your browser, but I been working on self contain the html page in a the JEditorPane which is great it does what i want, so I started working on the printing side and I am stuck...
The code I have was from a example (modified) but when I run the code I get the following error:
Exception in thread "main" java.lang.IllegalArgumentException: services must be non-null and non-empty at javax.print.ServiceUI.printDialog(Unknown Source) at gcclinux.co.uk.PrintReport.main(PrintReport.java:28)
The Line 28 equals to PrintService service = ServiceUI.printDialog(null, 200, 200,printService, defaultService, flavor, pras);
I am working on a Java program to monitor meal consumption by members of an organization. They swipe their ID cards, enter PIN, and number of meals they want. System knows if dining room is open and what meal based on time. The system then prints out a receipt on an Epson TM-T88IV receipt printer.
The system is running in console mode. My problem is that when the system prints, a Notepad window pops up for milliseconds and then the Java program loses focus. The screen reverts back to Windows home screen. I'm using Windows XP, SP3 and the latest Java build.
I am working on an assignment but I am not getting any out put and I couldn't fix it?The class HighLow below asks for three integers and prints the highest and lowest of them on screen. Your task is to write the missing methods high and low, which receives the integers user inputs as parameters and return the highest and lowest integers respectively.
import java.util.Scanner; public class HighLow { public static void main(String[] args) { int number1, number 2, number 3, high, low; Scanner reader = new Scanner(System.in);

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();
why am I not getting a proper shape of "Leftarrow"? The result should look like the following (the system draws the arrow abnormally, so the beginning should a real ARROW:
*
* *
* *
* * * * * * * * *

here is the class:
Java Code: public class LeftArrow extends ShapeBase { private int lengthOfTail; private int widthOfArrowHead;
class shape{ public static void main(String [] args){ for(int x =0 ; x<=6;x++){ for(int y =0 ; x > y ; y++){ System.out.print(x); } System.out.print(" "); } } }
i java a project with java draw golf course and currently working on 2 combo boxes to change shape of the flag on the post and fill color as well on combo box item change. I have below code. as am new to java what to do next.
import java.awt.*; import java.awt.event.ItemEvent; import javax.swing.*; public class GulfCourse extends JPanel{ public void paintComponent( Graphics g){ super.paintComponents(g); //draw green oval
