Nearly all of hte sample Java Applet is pre-made by the teacher. I'm running into the issue where, if I use the string arithmetic inverse method provided by the textbook, it refuses to recognize variables such as s1, s2, and i. So I'm now trying to use stringbuilder, and running into a similar issue. It doesn't recognize hte symbol "buffer". Under the "else if ( e.getSource() == inverseStr ) {" is where my code starts. The "Your Code Here" was put there by the teacher, and I'm just using it as an easy way to create blank lines if I delete a method that isn't working for me in the above section.

When I launch the applet in TextPad, there will be an Inverse button, and when I click that, it should reverse the word provided in the applet window, and show it in the inverse there. I had the StringBuilder working once, but it showed its result in a separate command prompt.
my idea is auto recognize when i put image like survey and that survey has shape box and it random area location and some shape box also character and number and can generated data that recognize in csv file.
I have this code that outputs the tfidf for all words in each file in the directory. I'm trying to transfer this to a matrix where each row correspond to each file in the directory and each column to all words in the files and I have some difficulty in doing it . Here is my try
public class TestTF_IDF { public static void main(String[] args) throws UnsupportedEncodingException, FileNotFoundException{ //Test code for TfIdf TfIdf tf = new TfIdf("E:/Thesis/ThesisWork/data1"); //Contains file name being processed String file; tf.buildAllDocuments();
I first time tried Java web service sample example using eclipse with axis2. First i wrote the provider class. Then by clicking create Web Service from the provider class It will show the following error "IWAB0014E Unexpected exception occurred." I have attached the screenshot for reference.
A getting started app is fine, need to understand of deploying a sample application to WebLogic server. Any particular configuration during WLS install?
My code below creates the 2 files successfully, but it is not able to write the sample data into the newly created file. I can't figure out the reason why.
Another strange thing is that when I tried inserting System.out.println calls for debugging, nothing prints out.
I'm using jdk7 and I get this error when I compile Exception in thread "main" java.lang.Error: Unresolved compilation problem: at First.main(First.java:16)
For a project I have to create an online survey, I cannot use a per-made online survey system because I have really specific needs that no pre-made system can satisfy, so my idea would be to create it in java and store the data in some simple text file, which are fairly easy to work with in java. My question is, is it possible, and if yes how difficult is it, to put the entire thing online? What worries me isn't putting the applet itself online, but the text files that should collect the data, I already have the website to host it.
I am trying to pass parameters from he following HTML file to an applet. the applet is not initializing and the iam getting the following error on the console. I also have both the html file and and the java applet under the same source file in eclipse.
java.lang.NumberFormatException: null at java.lang.Integer.parseInt(Integer.java:542) at java.lang.Integer.parseInt(Integer.java:615) at applet.DisplayMessage.init(DisplayMessage.java:16) at sun.applet.AppletPanel.run(AppletPanel.java:434) at java.lang.Thread.run(Thread.java:745)
Here is the html file
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>Insert title here</title>
I like to know how to write root function in java applet. I know it in java function. Ex:
import java.lang.*; public class Maths { public static void main(String[] args) { // get two double numbers numbers double x = 9; double y = 25; // print the square root of these doubles System.out.println("Math.sqrt(" + x + ")=" + Math.sqrt(x)); System.out.println("Math.sqrt(" + y + ")=" + Math.sqrt(y)); } }
working fine. but If I tried in applet it's not working. Ex:
I have an applet coded to recieve an image and upon mouse press i wish it to be cropped. For some reason its not implementing, I just think my brain is no longer doing what i think it should be or something, along those lines.
I am trying to go about making this applet a bit different then normal. The issue I am having is it is drawing an applet but, not the right dimensions, it's able to be resized, lastly the background color is not being set. I mean, I suppose I could call paint() and just draw it out but, I read that I could make the applet pop out to the dimensions I would like. None of this is working sadly.
I have An Issue With My Java Applet. Im Trying To Share My Variables With Another Class, But Its Not Working.
Class 1
package com.Tobysmith10.game.main; import java.applet.Applet; import java.awt.Graphics; public class Game extends Applet{ public void init(){ setSize(850,480); public void paint(Graphics g){ g.fillOval(x,y,20,20); } }
Class 2
package com.Tobysmith10.game.main; import java.applet.Applet; public class gameLoop extends Applet implements Runnable{ public int x, y; public void run(){ while(true){ x = 100; y = 100; } } }
So im sharing the x and y variables with the Class 1 , but I get yellow lines under it and when i run the program, it crashes, how do I get class 1 to recognize the variables from class 2 ?
Working on an assignment for a class: Create a DESKTOP application that allows you to open an image file and enables you to zoom in on or out from an image. I believe all I need is too create an open button to open the actual image file, instead of the html link, this code is an example that the teacher provided.My current code:
I've been using a Java applet for sports tables.It has been very useful for me. However, the recent developments from the people at Oracle have made this program impossible to use. The point is that I need this program and I need it fast.I've been in touch with the person who once created this applet and he has no intentions at all to upgrade it or do anything to make it function. How to make the program works with their new updates.

I am trying to design a generic RPG game. The issue I am having right now is in my Class I have a subroutine (think that is the correct term) that is basically set up to hold a series of Print Statements. I am really just trying to get some Values that are stored within the Applet, have them assigned to their correct variables and then returned in the print statement. Yet, when I run the applet it just pops up the Applet blank and gives me a long list of errors and I really don't understand when they mean.
Here is the code:
The Class
