Write A Class Called Coin Which Will Be Used By A Program Called CountFlips

May 1, 2014

i am trying to write a coin program:Write a class called Coin which will be used by a program called CountFlips.

1. The class, is an object created from this program. It is composed of data values and methods. It should contain a main method and should output the number of flips done (an integer that will be read from the user), the number of heads and tails that occur.

2. The CountFlip class will flip a coin multiple times and counts the number of ‘heads’ and ‘tails’ that result. This class should have a method called flip() of type void; a method called isHead() of type Boolean and a toString() method that will return the current face of the coin as a string.

So i created 2 classes, one called Coin.java & the other CountFlips.java,

PHP Code: package test;
public class Coin {
private final int heads = 0;
private final int tails = 1;
private int facetype;
private int flips;

[code]....

Write A Program Called GeometricMean

Nov 24, 2014

Write a program called GeometricMean that prompts the user to

1.Enter the number of values (total number of instances) that should be processed

2.A set of values to be processed (in a while loop)and then calculate the geometric mean of the values entered. You should use a while loop to perform the multiplication part of the calculating the geometric mean. The program should output the initial data and the labeled geometric mean. Consider printf, and DecimalFormat.

My Program:

import java.util.Scanner;
public class GeometricMean{
public static void main(String[] args) {
Scanner keyboard= new Scanner(System.in);

How To Write Instance Method For Rectangle Class Called Contains

May 29, 2014

Write an instance method, contains, that has one explicit parameter of type Rectangle. The method should return true if every point of the rectangle determined by the explicit parameter is on or within the rectangle determined by the implicit parameter. It should return false otherwise.

This is what i did so far?

public boolean contains(Rectangle other) {
Rectangle intersect = Rectangle.intersection(this, other);
if ((intersect.left == this.left) && (intersect.bottom == this.bottom) && (intersect.width == this.width)
&& (intersect.height == this.height)) {
return true;
} else {
return false;
}
}

Write A Method Called AddToOverThirty Which Takes Array Nums3 As A Parameter

Apr 22, 2014

i have to "Write a method called addToOverThirty which takes the array nums3 as a parameter. It adds 1 to all numbers that have a value greater than 30 in the array.

Add a call to the addToOverThirty method, then display a message telling what the output is followed by the results For example:The nums3 array after adding 1 to all numbers greater than 30 is10 6 15 and so on (check with the values you assigned to nums3)"its pointless because we were told not to make the array have a number over 30.

import java.lang.*;
import java.util.*;
public class LastProject
public static void main(String[] args) {
int nums1[] = new int[15];
int nums2[] = new int[15];
int nums3[] = {5,2,15,8,26,22,1,29,4,23,30,11,19,6,24};

My team DBA told me that " The user server process is oracle". My script shell resides in all RAC server file system the last result looks as follows:

Create A Class Called Dice To Represent SINGLE Cube

Apr 15, 2014

I need to work on this "Dice" program. I've done it twice already. I've also been pouring over examples on here and elsewhere online, but none of them exactly match what I'm doing, as they all say "Pair of Dice".Mine says: "Create a class called Dice to represent a SINGLE cube". It should have a method called roll() that randomly selects a number from 1-6 for the value of the dice."

It has to use java.util.random, not math.java, and it has to have numberShowing:int, roll():int, and main() all in it.The last part reads "Create a test main method for the Dice class that creates a dice and rolls it many times. Can you keep track of how many times a number comes up? Describe how or implement it in the program." I have started at this computer for hours, and read as much info as I can.

Swing/AWT/SWT :: Program Doesn't Close Though WindowClosing Event Called

Mar 25, 2014

I use the right term, release resources because after clicking the close button, the DOS prompts becomes unresponsive. So I have to close the DOS prompt, then reopen it, then type in the path again for the Java folders. Can you check where did I go wrong with my code? Is my placement of the WindowListener and WindowAdapter incorrect? Please refer to my code below:

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.io.*;
public class Proj6exe1 extends JFrame implements ActionListener
{
DataOutputStream dataLabas;
JTextField rainFallField;
JButton submit;
String strRainFall;
JPanel proj6Panel;

[code]...

I have other programs where the placement of the WindowListener and WindowAdapter are as exactly like this (within the class constructor block) where they close correctly and some that behave like this, that renders the DOS prompt unresponsive.

JSP :: Custom Tag Not Called At All

Jun 30, 2014

I am working on a project that uses a custom tag in a JSP file. Here is the tag descriptor

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE taglib PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.1//EN"
"http://java.sun.com/j2ee/dtds/web-jsptaglibrary_1_1.dtd">
<taglib>
<tlibversion>1.0.0</tlibversion>
<jspversion>1.1</jspversion>

[code]...

Everything seems working fine except that the custom tag handler does not get called at call. I set breakpoint and it never stops there. The JSP page is displayed fine, only not showing the custom tag content and there is no logged error/warning from the log. The tld is found fine. Like what classes called/validated the tag handler so I can logging those classes at DEBUG level to see what goes wrong.

Polymorphism - Which Method Gets Called

Jan 29, 2015

While studying polymorphism , i have some doubts that i am unable to clarify ..... Here they are :

Suppose our inheritance ladder be :
C1 <- C2 <- C3 <-....... <- C100
where C1 is most general (superclass) and C100 is most specific class .
Now , if i write java code in my main() :

C21 Obj = new C100();
Obj.someMethod();

So, what will happen in scenarios as given below :

Scenario - 1) If someMethod() is only defined in C1 ? How will compiler search for this someMethod() ?Will it be executed ?
Scenario - 2) If that someMethod() is static and only defined in C1 , then how will it be searched and executed ?
Scenario - 3) If someMethod() is only present in C100 , then what will happen ?

Method Called At Start?

Nov 24, 2014

So, I have a gameOver() method that should when oval goes out of bounds abort game but, as soon as I start the game it runs the gameOver method. I've been looking over it for a while trying different things. I think what stood out to me is removing the abort sequence the game runs mostly as it should after, popup is closed and that if I replace game.gameOver(); with ya = -1 the ball bounces off the wall.

gameOver()
public void gameOver(){
JOptionPane.showMessageDialog(this, "Game Over", "Game Over", JOptionPane.YES_NO_OPTION);
System.exit(ABORT);

Servlets :: Filter Not Being Called

Nov 10, 2014

I have Filter that is randomly being called and randomly not being called without any logical reason...The mapping is very simple:

<filter>
<filter-name>MyFilter</filter-name>
<filter-class>com.me.MyFilter</filter-class>
<init-param>
<param-name>ignorePaths</param-name>
<param-value>res/</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>MyFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

[code]....

So, init is called, so it works... but most of the time the doFilter method is not being called at all... what am I doing wrong?

Recursive Method Called RangeSum

Oct 3, 2014

I'm trying to understand the concept behind this recursive method called rangeSum. This method sums a range of array elements with recursion. I tried summing the elements of 2 through 5, and I tried writing down what actually happens when java executes the program, but what I get when I try to figure it out by paper is different from what netbeans gives me. Here is a snapshot of my scratch work as well as my source code. Netbeans gives me "The sum of elements 2 through 5 is 18" when I try running it but it I get 12 when I do the recursion on paper. I know that the source code is correct because it's out of the book but what am I doing wrong when I try figuring it out by hand?

XML Code:

package recursivecall;
import java.util.Scanner;
/**
* Author: <<Conrado Sanchez>> Date: Task:
*/
public class RecursiveCall {

public static void main(String[] args) {

Loss Of Data In ArrayList When Paint Is Called

May 23, 2014

Java Code:

public void draw(ArrayList<int[]> good,ArrayList<int[]> bad){
drawing = true;
goodToDraw=good;
badToDraw=bad;
System.out.println("Canvase/draw: Calling paint with a size of "+goodToDraw.size());
middleMan();

[code]....

What this does is two ArrayList are sent to the draw function.one called good and the other bad. Right now I am only working on good. What is suppose to happen is paint takes all the good coordinates and paints them but I seem to loose the arrayList size when repaint is called. You can see in the picture below of my console that it starts of with 20. Then because I was wondering if the scope was to short i called middleman to make sure that it held its size outside of the first function. Then finally it calls paint and tells me the array is empty. To simplefy..Why does my arraylist size go to zero when I call repaint?

Swing/AWT/SWT :: WindowListener Not Being Called When Clicking X To Close Window

Oct 14, 2014

I have added a windowListener to my JFrame but for some reason it is not being called when I click X to close the window. I need to send a message to a server to notify it that the client window is closed. Some code snippets below (some lines excluded for brevity):

public class ChatGUI extends javax.swing.JFrame {
....
setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE); // I have all the window constants here but has no effect other than closing the window without calling the listener...
addWindowListener(new java.awt.event.WindowAdapter() {
public void windowClosed(java.awt.event.WindowEvent evt) {
formWindowClosed(evt);
}
});
....
private void formWindowClosed(java.awt.event.WindowEvent evt) {

[code]....

This is resolved, needed to use...

addWindowListener(new java.awt.event.WindowAdapter() {
public void windowClosing(java.awt.event.WindowEvent evt) {
formWindowClosing(evt);
}
});

... instead.

JSF :: Lifecycle Is Not Getting Called After Servlet Filter Forward Or Redirect

Jul 11, 2014

I have a scenario here where the JSF lifecycle is not getting invoked. I have a filter, whose responsibility is to filter only authorized requests.the code of the filter is given below

public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
HttpServletRequest httpRequest = (HttpServletRequest)request;
HttpServletResponse httpResponse = (HttpServletResponse)response;

[code]....

now in the else block i am filtering the unauthorized requests, and sending them back to the Login.xhtml page of the application.The problem i am encountering here is that, the images and styles associated with the page are not getting loaded, what i am thinking is that when i am using redirect or forward, the FacesServlet is not getting called, and it is directly going to Login page i.e. no Lifecyle is being called.how to Filter the requests and at same time not lose the styles?
