(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.

Problem: On the form window, after pressing the button, it doesn't give any error and doesn't give any output. It doesn't reply and i have to stop compiling to exit. Why does the IDE do that, is it about my Java codes or Form Window codes ? ( I have two classes named Lexical.java and window.java. Working with Eclipse)
Details: I am working on a project that makes Lexical and Syntax analiysis of commands written in SQL Language. My form is in the attachment. If will be necessary i'll put my codes too.
Below is a method that is suppose to insert a value inside a stack based on the index. 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. After in which it would copy the holder value and place it at the top of the stack. (topOfStack variable is what the holder is copying too.)
public void pushExact (int index, String input) { String holder = ""; if (maxSize == 0) { theStack[topOfStack] = input; topOfStack++; } else if (topOfStack + 1 < maxSize) { for (int n= maxSize - 1;n >= 0;n--) {
I'm sure the solution is simple, but I cannot find it.
/*reads a hexadecimal number input by the user and gives the corresponding base-10 value */
public class HexConverter { static int i; //used to keep place in the hexadecimal sequence given by user public static void main(String[] args) { //declaration of variables String hexgiven; //the hexadecimal sequence given by user
I am having problems with writing a simple program to see if a number is divisible by 6.
public void run() { println("This program will display all numbers divisible by"); println(" 6 between 1 and 100."); int x =1; boolean divide =(x%6==0);
[Code] ....
It is telling that every number is not divisable by 6?
Why this extremely simple program seems to be giving me a negative value for amount of calculations done within one minute ( Just using it as a bit of fun to see how different computers in the office perform).
Java Code:
class Benchmark { public static void main(String[] args) { long endTime = System.currentTimeMillis() + 60000; int count = 0; for (int i = 0; System.currentTimeMillis() < endTime; i++) { double x = Math.sqrt(System.currentTimeMillis()); count = i; } System.out.print(count + " calculations per minute"); } } mh_sh_highlight_all('java');
I am getting results between -2.1billion and -3.4billion which to me would make sense since they are not the best computers in the world but I would be expecting a positive value?
I am having issues with the first part of my program. When I got to display what is in the textfile, it only gives me one name two times. I cannot figure out what to do with my outer loop in order for it to read and output the entire data file.
I am having trouble figuring out why java is giving me an error for the symbols. I will post the errors below the code.
Java Code: import java.util.Scanner; public class ShelbyHarms_3_02 { public static void main(String[] args) { Scanner console = new Scanner(System.in);
I have printed the result of my program into an output file.
For some reason I can't figure out how to get the file output.txt to actually print.
I've tried printing it like I would normally print a file but it's not working.
Java Code:
final PrintStream console = System.out; File file = new File("output.txt"); PrintStream out = new PrintStream(new FileOutputStream(file)); System.setOut(out); System.out.println(collection.toString()); System.setOut(console);
What do I do after this? mh_sh_highlight_all('java');
It seemed to me that the bufferSize is limited so that I can only have it less than a default one, how to increase it?
My question now is how to increase the size of buffer in order to read a larger InputStream ? BufferedInputStream() default size is private static int defaultCharBufferSize = 8192; private static int defaultExpectedLineLength = 80;
How to make it larger and working? I tried to increase the defaultCharBufferSize to 500000000 but it did not work!
I have this error that keeps coming up any time I select one of my buttons. It actually doesn't hinder the performance of the project, everything works. But I am concerned I missed something and errors are never a good sign.On a slightly different note, I would like to figure out what the best way to format my output would be? I would like it to display as "100.00 F". I have a couple ideas on how to get the F symbol (or other symbol) by inserting something like
String degreesymbol = "F" or whichever it is and then returning that in the output string later. I can't get the decimal formatted correctly and I don't know how to print the degree symbol.Here is the code
I'm doing to create miles/kilometers converter. If I put the mile, converting to kilometer is right. However, if I put the kilometer, converting to mile comes out wrong value. Which part is wrong?
I made a web app to test the ServletContextListener in tomcat according to the book head first servlets and jsps and used the code
out.println("test context attributes set by listener<br>"); Dog dog = (Dog) getServletContext().getAttribute("dog"); out.println("Dog's breed is: "+dog.getBreed());
in the listener class.But the output is showing the first line only and the second println() is not showing any output whereas my Dog class compiled successfully and I didn't see any NullPointerException as expected in the book but somehow it seems like the problem is in the 2nd line of code only but I don't know what.
I also tried to add a 4th line at the end with println() only but with a simple text even that is not running but when I put that same line after the 1st line, the output is shown.I am unable to see what has gone wrong in the 2nd line of code.
How do I put this code in a way that it works because I know it is probably something obvious but I cant find how to make the array readable without error. It is supposed to intake two values and output what day of the week it is.
Testing Program
Initial day: Monday Next day: Tuesday Next day again: Wednesday Previous day: Tuesday Next week: Tuesday Add 4 days from initial day: Friday
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;
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", "Kilograms", "Pounds"); System.out.println("---------------------------------------------");
I have a signed certificate from Entrust which I used to sign a DeploymentRuleSet.xml file. I placed the DeploymentRuleSet.jar in the proper location C:WindowsSunJavaDeployment, afterward the java control panel's security tab shows a link to "show the active deployment rule set" which did not exist prior to coping the file to the directory. When I click on the link a new window opens and says "Rule Set not found" ....
I have just tried to learn java this week [COLOR="#000000"]and I am being held back by this once installed java jdk I nav to the java file and the bin file and then the javac file to find that the below tab does not exist
A new window should pop up giving the properties of the javac, there should be an attribute called Location..I can see the location option in my documents but in no other folder
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 am having some serious difficulty getting my project off the ground. I have the following code:
