I'm quite new in android programming and I've meet some problem in push and pull method. I have created 2 activity in my app 1 of them call Push_activity and Pull activity(Code are shown below). The String that I keyed in PushActivity have to "transfer" to the PullActivity when the button is pressed:
I have designed an applet to simulate a stack (last-in, first-out) of strings. The applet consists of:
Two JButtons Two JTextFields Two JLabels A TextArea
The user enters text in the first text field then clicks the push button and it goes in the textArea. After entering several strings the user can click the pop button and the top string goes into the second text field. I am a total newbie and am stuck. I can get a string of text to push to the textArea and then pop it out; however I can't stack them LIFO. Most examples I've seen use integers and I'm not sure how to translate the concept to strings. I'm just not sure how the stack concept works even though I read the API webpage.
I have some data in the database and values can be added on demand. so when ever the value added to the database i need to promt that message to all users which are accessing my website, so how can i acheive this....
I'm unable to get the output for "AverageDriver" to print correctly(5 scores in descending order and average). The output displays the scores the same way they are entered and the average is always zero. The output for the Average program works fine and with the correct output.
import java.util.Scanner; //This class keeps 5 scores entered by the user public class Average { private int[] data; private double mean; public Average()
I'm trying to pull the authors from this Json object but I'm having issues trying to pull the author only, I'm only able to get a huge string which is a valid JSON object i tested it in [URL]
This method keeps throwing a NullPointerException. Not only that, but its not doing what I want it to do.
Heres the code:
/* Remove all the numbers from the queue and push onto the stack until an operator is reached */
private static void processQueue() { // Check what is at the front of the queue. If an operator is found or the queue is empty, exit method. while(queue.front() != null || !queue.front().equals("*") || !queue.front().equals("/") || !queue.front().equals("%") || !queue.front().equals("+") || !queue.front().equals("-")) { stack.push(queue.removeFront()); // push the operand onto the stack } }
Here is the method that calls the processQueue() method
/* Process the mathematical expression using a stack and a queue */ private static double processExpression() { // insert all elements from the stack to the queue for processing while(stack.top() != null) { queue.insertBack(stack.pop());
Program to pull prime numbers between two entered values,
import java.util.Scanner; public class question6 { public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.println("Enter lower int:");
This program reads off of a text file that I have attached to my post. It is supposed to:
display the total sales for each week the average daily sales for each week the total sales for all of the weeks the average weekly sales the week number that had the highest amount of sales the week number that had the lowest amount of sales
I can get everything but the very last one. In my code you will see that I tried to use a really large number so it would pull out the lowest amount, but it still didn't work: low = 100000000;
SalesData.txt (173bytes) Number of downloads: 29 import javax.swing.JOptionPane; import java.io.*; import java.text.DecimalFormat; import java.util.Scanner;
I've been trying to pull data from another class file "Calculations.java" and have it be displayed in a TextField in "DataAnalyzerGUI.java". Here is how the hierarchy is broken down for my assignment:
I tried to run the program in eclipse(See Attachments 2 3 4) but I got the following errors(Attach 1), I have attached them as screen shots.

Since am new to java and hadoop, I want to know the procedure step by step in a brief manner.run this program and rest of the two statements successfully.
i have programmed a game using JPanel and JFrame. My App is of this type (if this is relevant to the problem):
public class Main extends JPanel { private JFrame frame; public static void main(String[] args) { new Main(); } public Main() { frame.setSize(WIDTH, HEIGHT);
[Code] ....
The problem is, When i export the file in eclipse as Runnable jar file,and run the exported file, it gives me a blank screen (white default) and nothing is running. Whereas, normal debugging of the game is working quite well.
i have an older file I was working on 2 months ago and when i try to open it in eclipse I get a message corruption error. I know this is not possible since I was just working on it a while back, and it's the same program version as what i am currently using..Or would I do a file import instead?
it gives me an error at the end class part some syntax error insert "}"..

I just started Java programming bout 3wks ago and using jGrasp since then. But ive started using eclipse and just wondering if it can be set up to use allman style? I dont like having to use tab and backspace to get my brackets in line and neat. I decided to ask before i went snooping around the settings and mess something up since im not to familiar with it right now.
I'm new to java programming and I've been trying to make my first program in eclipse for a while, and I finally managed to do that. Well my problem is that I want to be able to use my program without having to open eclipse and opening my program from there, is there any way to do that ?

I'm programming a game in Eclipse using Java for Android. I was wondering if any good example of a Health bar using Images. All I can find is people using the progress bar, but i feel that's unprofessional looking.
My goal is to layer 2 images. 1 being the frame of the health bar, 1 being the value of the health bar. I figured it would be something like moving the value health bar image few pixels over depending on the variable of health.
I write lot of java code everyday. Sometime in hurry I forget to close the resources (connection,file,etc,) in JAVA6 and this causes memory leak issues. I am looking for an eclipse plugin which can complain for these minor mistakes. Also I am looking for some more eclipse plugins which can improve my source code quality like naming conventions, code redundancy, complexity, too long code outside methods, etc,.
I am watching BrandonioProductions on youtube. His videos are pretty good, but he doesn't seem to get errors where I get them. Here is an example.
public class compareUnequal { public static void main(String[] args){ compareTwo(); } public static void compareTwo(){ String x = "david"; String y = "Notdavid"; if (!x.equals(y)){ System.out.println("Not equal"); } } }
It runs ok, but asked me to proceed when there is an error, but I can`t figure out where the error is!
Follow the //? FIRST and SECOND notes, then I understood that Java has GOTO as Keyword for future versions and that usually one can avoid GOTO using break inside the cycles, but I need a jump( salto) in the code.
import java.util.Scanner; public class ArrayOrdinati { public static void main (String[] args){ int[] Array = {5,3,1}; int e=Array.length; int b;
I'm trying to JFileChooser to open up a window. I'm just trying to learn how to use it for a school assignment this week. The problem is I can't get anything to show up. I can create a new window and print to the console without errors, but JFileChooser doesn't do anything. No errors either.
import java.awt.*; import javax.swing.*; public class TestingStuff extends JFrame { public TestingStuff() { setTitle("This is a new window!"); setVisible(true);
