Terminal Within Java GUI?
Sep 19, 2014
I have developed a Java GUI by using Netbean. The user interface will get the user parameters that are needed by a c++ program (which I also developed). Upon clicking the run button java will execute the c++ program with the inserted parameters by launching and X-term session (using Runtime.getRuntime().exec(command) ) . Everything works fine in this way. However I do not find very elegant to launch an external terminal to run the C++ code. Is it possibile to have a terminal that is integrated within the java GUI? And run the C++ code within it?
Moreover, since the C++ code may take several hours to finish the job is there a way to read its output and use it in order to make, for example, proceed a progress bar?

So when writing my first "Hello World" app everything seemed to work just fine. I wrote the code, compiled it, and then ran the class file and it worked, I got the return Hello World! But when I tried to write another app which is basically the exact same thing just a different sentence, I keep getting a bunch of error codes saying illegal character. I did everything the exact same. I am using Text Edit on a Mac and using Terminal to execute the Java code.
Here is what I wrote....
public class MyFirstApp
{
public static void main( String[] args )
{
System.out.println(“i rule the world!”);

I am trying to build and IDE for NASM in Java for Ubuntu. There are other IDE's for NASM but they are in C or C++. So i thought i should try making one in Java. Well I am done with the GUI part.
How should i link the NASM compiler to the IDE.
Or
There is another way like "DEV C++ IDE" does in Windows is that it invokes the CMD and runs it in that so i could try doing something like that by invoking the TERMINAL in Ubuntu and running it in that. Does java have an API for this purpose.

I want to develop a Java program that uses OpenScript APIs to test my applications. The OpenScript framework automatically creates the Java Code so I was thinking of either using this code or create my own using the APIs.
I tried both options using NetBeans but I'm getting errors everywhere starting with the library import. I'm pretty new to Java so I'm sure I'm missing a lot of things here. I pasted the code below from the OpenScript framework that want to use in a stand-alone file for your reference.,
import oracle.oats.scripting.modules.basic.api.*;
import oracle.oats.scripting.modules.browser.api.*;
import oracle.oats.scripting.modules.functionalTest.api.*;
import oracle.oats.scripting.modules.utilities.api.*;
import oracle.oats.scripting.modules.utilities.api.sql.*;

I've written a java application with several classes all in the same .java file. It works just fine. Now, I've broken it up so that each class has its own .java file. Still works fine. My next step is to put those classes into a package, but I'm not about to get the program to run.The .java source files are all in /home/user/src
I've set the CLASSPATH to /home/user/src..All of the source files have "package com.myfirm.program" on the first line.I compiled the application with:
javac -d . File1.java File2.java File3.java (etc...)
the compiler created the directory: /home/user/src/com/myfirm/program and put all of the .class files in there.So how do I get the program to run? if I run from /home/usr/src
java File1
I get: Exception in thread "main" java.lang.NoClassDefFoundError: File1 (wrong name: com/myfirm/program/Program)

The title of Question might seem old and previously asked.But I have a Question that what is difference between javaSE and Java EE.Although I knew what comes under JavaSE and What is under JavaEE.But My question is that.
What happens when we add PATH in our Environment Variable How does Eclipse or Other IDE use it?
Second Question is.
For Java SE we declare a Path Variable but for Java EE we do not add any library?(I know we add some jar file like for Servlet(Servlet-api.jar) and for EJB(Ejb.jar),But What is actaul difference?

I know about coding in general, Java, C, Python, SQL etc. but I barely know anything about making code come together on the web. I have a vague idea about what things like libraries and frameworks are,I'm interested in making a web application with which relies on Java do to the data processing. The idea is that the user inputs some messages, clicks submit, the text is taken away and processed, and the results are displayed on the screen. I would like the UI to be smooth with a modern look and feel.
Also, I usually do programming on Windows but I could also use Linux, so if I'll come across any specific drawbacks using Windows.

Write a function (or functions) that given a collection of files will produce a sum of integers from each line of each file. Each file can have any number of lines from 1 to N. Each line can contain only one integer and no other alphanumeric characters. All of the numbers from all of the files should be added to the final result. The result is just one number.
For either, what we are looking for is:
1. Clear separation of concerns
2. Well defined objects / interfaces
3. Application of good OO design principles to solve the problem
4. No code duplication
5. Test Driven Development
6. Well refactored code
7. Well tested code

I'm converting from ASP to Java for a legacy site. I believe the first part of the if statement is right but I'm having an issue within the else staetment. I'm getting date is undefined, I've tried using getYear and getDate but have not been successful.
ASP:
If Request("action") = "results" Then
aMonth = Request("selMonth")
aDate = cint(Request("selDate"))
aYear = cint(Request("selYear"))
Else
aMonth = UCase(MonthName(Month(Date()),true))
aDate = Day(DateAdd("d",-1,date()))
aYear = Year(Date())

how to use JFrames and button and so on in Java. I found this video on youtube and followed it along, however even though my program is virtually identical to his, I'm still getting errors.
Here's the video I was watching: Video
And here's my code:
import javax.swing.*; //Imports JFrame and JButton for use
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.*;
import java.awt.*;
import java.awt.event.*;
public class swing
[code]....
The reason why I'm importing some many things is I'm trying everything to try fix my problem.
He's the error messages I'm getting:
frame2.add(panel);
^
C:UsersWindows 8Documentsswing.java:42: error: illegal start of expression
frame2.add(panel);
[code]....
I used to make the button just create another frame without additional labels but I changed it to be even more similar to his program just to rule everything out. Also initially my program varied quite a bit, I've changed everything to be like his. Even without the ";" error I got, I kept telling me I was not allowed have my class as static, even though the guy in the video has it set to static. Also I don't think my "setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);" is working as it doesn't change color.
I think the problem is with my panel, it isn't adding to the frame for some reason.I'm using TextPad7 and I'm using Win8.
C:UsersWindows 8Documentsswing.java:42: error: '(' or '[' expected
frame2.add(panel);
^
C:UsersWindows 8Documentsswing.java:42: error: illegal start of expression
frame2.add(panel);
[code]....
I would also like to point out that some of the comments are out of date and are referencing the way the program was before I made it just like his. For example I know my second class isn't inheriting the first class.
