I tried many times to return a string from java project to an android project But it keeps sending incorrect values as in 2 as it should be 1 here is an example.
Java Project:
boolean somethingboolean = false;
if(something.equals("1")){
somethingboolean = true;
}
public static String getString(){
if(somethingboolean == true){
[Code]...
Android project:
System.out.println(JavaProject.getString())
and in the android project it prints "FALSE"
So what should i do?
I'm doing a project and my code won't compile.

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.
So I am working on a PostFix calculator that is used in command line for a class project, and I am having a little trouble on developing a memory for it. I have been told to create a hashMap and I have researched it and understand the basics of it. I have the calculating method working, but what I am having trouble trying to implement a way for the user to declare variables. For example this what the user should be able to do:
> a = 3 5 + 1 -
7
> bee = a 3 *
21
> a bee +
28
[code]....
I just need to be able to save the answers as a variable the User names, such as the example and let the user be able to use the variables later.
So, I've been working on a school project for a couple days, and I have my code written out but I can't fix the compile-time errors. The prompt for it is here:
Write two programs: one using the String class and one using the StringBuffer class. Your programs should store a set of Strings in an ArrayList and print those Strings in the order by which they are added. The output of your programs should create a complete sentence.
I am stuck on the first program.Here's my code for the first program:
Java Code:
import java.util.ArrayList;
public class SentenceNormal {
public static void main(String args[]) {
String n1 = "My ";
String n2 = "favorite ";
String n3 = "football ";
String n4 = "team ";
String n5 = "is ";
String n6 = "the ";
String n7 = "Seahawks";

As a brand new with Java I've created a small "Hello world" program using eclipse.
I would like to create an exe file from this application. Therefore, I need the jar file.
I can't find such a file with that extension in the folder where I saved the java project.
How can I manage this file?
I know it is a very basic issue, but as I mentioned it is the first "Hello world" test...
Hello World program. We had to build it. Write a basic Java program that will implement one class to store a state of a project. The class should have one property to store a textual name of the state. When a object of this class is created the initial state should be "Open".
1) Class should have one method next() which will move the project to the next step in the sequence: Open - In progress - Closed.If next method is called for a project in the Closed state it should do nothing.
2) Class should have a method close() which will move the project into the Closed state.
3) Class should have a method print() that will output a current state of the project.
Submit a java code file as your assignment. Do not hesitate to contact me if you have any troubles with the assignment.
I have been working on this thing for almost a week, and really don't have a clue on what to do. I know I have to use a string = open, and I know I have to create an object. I don't have a clue on how to do this. I have read the chapter so many times, I almost memorized it, but what he wants is nothing like our demo in the book. the Book used set and get, and utility scanner, but he doesn't want any of that. Just a basic code that will move from Open --- in progress --- closed.
The best I can tell what he wants is when I set the object to open it will display " project is open", then when I set it to " in progress" it will read project is "in progress". I don't have a clue what close is suppose to do, or the print method.
I have make a simple grade average project and can't figure out how to ask the user if they want to enter more grades to average and run the app again.Here's what I have so far.
import java.util.Scanner;
public class Average {
private static Scanner kb;
public static void main(String[] args) {
kb = new Scanner(System.in);
[code]...
How many grades do you wish to average?
I'm done with my project and I'm not trying to make it into a jar with JGrasp... I start by making a project then I click the option to make my project into a jar... Everything works but when I try to run it it says that the main class cannot be found... How can I fix this?

View Replies View RelatedI inherited a web application and am trying to build it. I recently installed JasperSoft Studio 5.5.0 final on my developer machine. I also have Eclipse Juno on my developer machine. I was advised by the previous developer to put some of his Jasper .jar files into my web app's lib folder. I did do this and now the localhost will not run, it is generating this error:
org.apache.jasper.JasperException: java.lang.NullPointerException
org.apache.jasper.servlet.JspServletWrapper.handleJspException(JspServletWrapper.java:502)
org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:430)
org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:313)
org.apache.jasper.servlet.JspServlet.service(JspServlet.java:260)
javax.servlet.http.HttpServlet.service(HttpServlet.java:723)
I went out to the lib folder and saw these files:
jasperreports-5.1.2
jasperreports-applet-5.1.2
jasperreports-expressions-1.0.0
jasperreports-exprfunction-1.0.0
jasperreports-fonts-5.1.2
jasperreports-javaflow-5.1.2
The version on them would appear incorrect given my version of 5.5. I am new to Jasper Reports. I suppose I could google on the .jar files and get the ones that belong to the 5.5.0 final and put them into the directory to see if Apache Tomcat 6.0.39 likes that better. And then start the server. If it doesn't like them, I guess I could remove them and continue, but I would prefer to have the Jasper Reports up and running.
My second question about the Jasper Reports is how do you tell the IDE where the Reports are located?
I bought a certificate to sign my jars, if a deploy my applet in a html file with out framework, just html and js, the works great, I can call from javascript all public methods from the applet. The real problem is when I try to deploy the same signed jar on a adf project in Jdeveloper. Does not work at all and java execute some warnings and later applet is block, the message say something like "exist some jars signed and not signed" But I am sure that all jars are signed...
I got this:
applet console:

All jars are signed, dependencies too.

View Replies View RelatedI have a gameengine stil partially in the works for pc made in java, I am attempting a port over to java but certain classes and other fuctions are not available for android that there is in java. this means that my render engine, gameengine and a couple of other clases therefore don't work.
My question is, is there anyway of using the gameengine classes that work into the project so that all i have to do is declare within the engine what i want to export for wheather this is android or java. or importing packages from the game engine project and directly linking with the ability of re-writing the odd few classes that do not work.

I am making a program that reads a set of numbers (e.g.: 8 1 6 3 5 7 9 4 2) and prints them into a matrix.For example:
8 1 6 3 5 7 9 4 2, will produce:
8 1 6
3 5 7
9 4 2
When taking in these numbers from the user, I am not allowed to let the user state what size the matrix is (e.g.;3 x 3). Instead the program needs to determine that itself. I have written the code below to count the number of numbers inputted, but now I am stuck as to how to get them into the array. I have what is suppose to be my array written, but it is not function yet.
import java.util.*;

public static void main(String[] args)
