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:

So I need to print out the table of conversions from kilogram to pound and from pounds to kilograms. I think I have done a while loop correctly, but it is hard to actually check it since I do not have proper output format. I have tried also %4.2f format option however could not find the proper position in the print.
public static void main (String[] args){
System.out.printf("%10s%10s | %10s%10s

"Kilograms", "Pounds");

When I click on the link a new window opens and says "Rule Set not found" ....

I thought it would be easier to copy the value, if any, that was in the index into the variable holder and replace it with the input value.

Okay so I need to be able to read a file and then be able to find the longest sequence of increasing numbers.
So if the file was this, (this is Ass1Q2_test4.txt)
97 47 56 36 60 31 57 54 12 55
35 57 41 13 82 80 71 93 31 62
89 36 98 75 91 46 95 53 37 99
25 45 26 17 15 82 80 73 96 17
75 22 63 96 96 36 64 31 99 86
12 80 42 74 54 14 93 17 14 55
14 15 20 71 34 50 22 60 32 41
90 69 44 52 54 73 20 12 55 52
39 33 25 31 76 45 44 84 90 52
94 35 55 24 41 63 87 93 79 24
the output should be,
(5,0) with cost 12
(6,0) with cost 14
(6,1) with cost 15
(6,2) with cost 20
(7,2) with cost 44
(7,3) with cost 52
(7,4) with cost 54
(6,3) with cost 71
(5,3) with cost 74
(4,3) with cost 96
Greatest path is of length 10.
Now, the code that I have works, kind of. Instead of recurring several times at each point, it only recurs once.
So say I'm looking at (1,1). With (1,1) being 57. The area around it looks like this.
97 47 56
35 57 41
89 36 98
Now when I look at it, there are several paths it can take. It can go 57, 97 or 57, 89 or 57, 98. However, I'm pretty sure that it just uses the first one that corresponds with the first if statement that is valid. So I start checking north of the value, then northeast, then east, then southeast, which at southeast is where I find my first greater than value. After it finds it's first valid number, it then continues from that number, instead of checking if there are other longer paths stemming from the original value.
In conjunction with that, you can see that the printout just returns all paths from each value. Which isn't what I want. I need a way to store the longest current path, then check each path after to see if it's longer. If it is, it's replaced, if not, it stays the same.
I've also attached Ass1Q2_test4.txt

You are given 2 files - "testcase.txt" and "validwords.txt".In testcase.txt, the sentences are written without any space inbetween/for ex: this is a sentence which looks ambigous.You are to insert a space at the proper place by breaking the sentence into correct words, ex o/p: this is a sentence which looks ambigous.validwords.txt contains all valid words (as 1 word per line). If you find a word that does not match, replace it with ####. After correcting

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'm going to make tiles for my RPG game, instead of drawing each shape of the tile, I will just draw the full tile in a spritesheet. I will create a sprite sheet of shapes that I want to clip somehow or use to cut the original full image into the shape I want. How can I, take a Buffered Image, cut it's shape and perhaps add something, giving me a Buffered Image of a cut tile with possibly added features that I can then draw with Graphics?

How do i center it to create the shape?
I'm making my 2D Java game, in my own style, in my own way. I'm trying to make it as code efficient as possible and compact, it usually is easier to change that way. I'm going to use BufferedImage subdivision on tilesets to take out tiles that I need, rather than creating multiple images with a tile each. Now, I've made multiple water tiles, for how they would be arranged differently.
So let's say you have a single water spot, it will be circular, you have two water spots, you have a tile-thick line with circular ends like two little water spots connected, this makes the game look more advanced, better, more realistic and good in many other ways. But, I found that an avarage amount of shapes needed is 25. I thought, how could I make this more efficient?
Could it be possible to use like shape cutting tools or something that would take out a specific shape of a single water tile to leave out all the different shapes, this is a good idea because I could use these tools for all kinds of different tiles in order to make specific features. By tools I mean simple black shapes which will remove the unwanted parts of the tile to form the wanted shape.

I am currently trying to make a Tetris game, so far I've got a class drawing that extends a JPanel as my canvas, a class Square that is 1 square(20 by 20) and a class LineShape that should draw 4 squares above each other. The class Frame way below is merely to set things up.
Currently i'm able to draw objects of my class Square, so I made a class LineShape that combines both and makes a 4Square long line.
My problem is when I try to draw an object of the class LineShape, it shows nothing, removes what is already painted(the square) and gives an error message:
Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException
at LineShape.<init>(Screen.java:96)
at Drawing.paint(Screen.java:79)
I put my classes together so you can copy paste and run, make a new screen to start, to see the problem occur, go to the drawing class's paint method and uncomment these lines:
// LineShape shape = new LineShape(this);
// shape.paint(g);
Below are my classes:
import javax.swing.*;
import java.awt.*;
public class Screen {
private Frame frame;
private Frame inputFrame;
private JPanel panel;

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.

Here is the code:

I am working on a UI in JavaFX and create several instances of a custom control class. The control consists of a Pane which wraps several other containers, one of which contains a Circle shape.
At one point, I instance this control and access the Circle shape directly. I transform it's center coordinates (which are always {0.0, 0.0} ) to Scene coordinates. The problem is, the transformation always yields coordinates that correspond to the upper left corner of the control's root pane.
In other words, it's as if the Circle is positioned at the upper left corner of the custom control (when, in fact, it's positioned near the lower right corner).
I have other instanced controls already in the scene, and they do not have this issue - converting the Circle's coordinates to scene coordinates works as it should.
It seems obvious that I'm accessing the Circle too soon - that perhaps the scene graph hasn't been fully traversed for the control and the Circle's position within the control's hierarchy hasn't been updated. I've verified that my attempt to access the Circle's center coordinates occurs after the control's initialize() method is executed, so how to ensure the control's scene graph has been fully updated before I try to manipulate the control...
Am stuck in a problem that asks to write a program using nested for loops to draw a V-shape of height "n" entered by the user with stars .
