Applet Won't Calculate Discount For Matinee Movies
Feb 21, 2014
I have an applet program here that allows the user to choose a movie then a number of tickets from a drop-down list. A check box should display for users to click so they can receive a discount for matinee movies. The user should be able to click a calculate price button to display the total cost and a clear button to clear each drop-down list and the check box. The program compiled but when I clicked the calculate button, it generated so many error codes like java.lang.nullPointerException and a lot more. I just wanted the program to work properly. Code below:
import java.awt.*;
import java.awt.event.*;
import java.applet.*;
public class Proj4exe2 extends Applet implements ItemListener, ActionListener {
Choice movieChoice = new Choice();
Button calcButton = new Button("CALCULATE");
i finished up a project here and seem to be running into some issues. I figured its my notation, when i ask a user to enter a number, if its below 10, it should *only* print "No Coupon." but what appears to happen is that the program prints "No Coupon" Plus the "discount coupon and % of purchase."
import java.util.Scanner; public class assign1c { /* Start of Class 1c */ static double cost; static double coupon = 0; static String x = "No coupon"; public static void main(String[] args) { // TODO Auto-generated method stub
These are the values I have. Basically I just need an explanation of how to code a statement so I receive the calculated discount of a Full or Compact.
Here is the excerpt from the code, I can copy the whole code in too if needed.
Java Code:
System.out.println("You selected Item1."); System.out.print("Have coupon? [Y or N]"); answer = kb.next(); if (answer.equalsIgnoreCase("n")) System.out.print("Price is 30.50 per day."); if (answer.equalsIgnoreCase("y")) >This is what I'm looking for< mh_sh_highlight_all('java');
i have created a frame with a menu bar displaying contents..now i want to set a username and password to that flame through an applet how to add applet to the frame??

import java.awt.*; import java.awt.event.*; import java.applet.*; class MenuFrame extends Frame{ String msg=""; int flag=0; CheckboxMenuItem debug,test;
I am facing problem when displaying my applet on jsp. I have convert my applet project into CustomColor.jar. my package is dcs.raj.MyApp
I have import my jar into project property. But still it is showing error on all browser, i have changed the java control panel > Advanced > Java Consol > Show console.
I have a java application in which when starting it a map is opened and a screen is captured. The capturing is in certain time interval. I want to enable the user to change the interval for the automatic capturing the map. I placed a text box in a JPanel. I want to pass the value which was entered in it to the html page which opens a Google map. Since I am new in java programming, I found that I can do it by using applets. I made an applet, and tried to call it in the html file. But now instead of opening the map file in a browser, it opens very quickly only black window.
Here is my applet:
package cege.ui; import java.applet.Applet; import java.io.IOException; import cege.ui.GuiMain; public class AppletTInterval extends Applet { private int TimeInterval=0;
[Code] .....
And the code in the html file where I try to call the applet, i.e. to pass the value which is returned by the applet is:
<script src= <!--"https://www.java.com/js/deployJava.js"></script> <script> var attributes = { id:'AppletTInterval', code:'cege.ui.AppletTInterval', width:1, height:1} ; var parameters = { jnlp_href: 'AppletTInterval.jnlp'} ;
[Code] .....
Can I use this way to pass a value from the java class file (from the JTextField into the html file?
I coded up a simple applet and some html with an applet tag and it tested out OK using the applet viewer. But it doesn't do anything (except draw a grey empty box 100x200) when executed from the application server. For the applicaton server test, I put the applet tag in the HTML Body of the JSP page i.e.
Technically, when you run the program, a gif page appears (that I put as a placeholder) and when you press the letter 'n' JCreator runs the program, displaying a character P on a .txt field made using the Notepad on Windows. You can move it left, right, down, and up andf it will move accordinly. However, each time I make such action, the compiler has to rewrite to whole .txt field with the new position.
My former tutor said that in order for it to be "real-time", we have to use an applet.
Is there any way to save variables while I'm using applet as single runnable .jar file?
For example if I start app first time some variable has value of 100. While using app it changes to 200. After closing app it disapear and next run gives me 100 again instead of 200. Is there any way to save that 200?
I need to create an applet that displays a grid of command buttons which I have done. I then need to create a new class that draws a silly picture of an alien, which I have also done. Where I am completely stuck and confused, is that I do not know how to get the drawing into the applet. My code is below. I really do not fully understand why this is not working or how to get it working.
import java.applet.*; import java.awt.*; import java.awt.event.*; import javax.swing.*; public class MartianGame extends JApplet implements ActionListener { DrawMartian aMartian = new DrawMartian(); DrawJupiterian aJupiterian = new DrawJupiterian();
I am a new to Java and currently doing a study on applets.
I was looking for the demo folder in the jdk but I cannot find it. I was previously using jk7_51 and now using jdk8. and both of them do ot have the folder. I downgraded to jdk6 but i still could not find the foler. I need it since i need to try out the applets that come with the jdk. What I should do?
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)
I am new to applets and I am trying to create a program to display color and font. See my code below, I am getting some errors below.

I am trying to run a Java applet (.jnlp) file through OSX. The purpose of the applet is to upload files to an SQL server. When I try to run the applet, I get an "Unable to launch the application" error because "No application resources are specified for this platform" After some digging , we noticed there are only resource instructions for "Windows".
Would there be any way possible to make this compatible in an OSX environment through a few alterations to the code, or would this be an issue that the original developers would have to resolve?
Here is the specific code pointing to the Windows Resources:
