How to make my program look nice. I have to create a mortgage calculator with no functionality, so it basically just has to be a window that looks like this:
Here's my code:
import javax.swing.*; import java.awt.*; import java.awt.event.*; public class MortgageCalculator { public static void main(String[]args) { CalcWindow calculator = new CalcWindow();
[Code] .....
Here is the output I am getting:
How do I make my program output look similar to the 1st picture?
I am unable to understand the use of String intern. Why not use Code 1 as given below instead of using intern as in Code 2? Both perform the same functionality.
I am trying to implement a file upload functionality. One of the requirement is to display a 'Please Wait!!!' message to the user while the upload is going on.

A team of programmers is reviewing a proposed API for a new utility class. After some discussion, they realize that they can reduce the number of methods in the API without losing any functionality. If they implement the new design, which two OO principles will they be promoting?
I just kinda get stuck when it comes to passing values into constructors, using main method or static method functionality. In theory i kind of understand how it work but when i type it, it's totally different! I have to have a junit test too but i guess i could do that in the end.
I have attached the assignment. So, how to proceed with this:
public class Flight { int flight_number, capacity, number_of_seats_left; String origin, destination; String departure_time; double original_price;
I have tried running the java application without adding the site to site list in java security tab. But I get a sand box message as APPLICATION BLOCKED BY SECURITY SETTINGS. How to run the java application without adding the site to site list in java security tab.
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.,
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:
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.
When I try to convert this value, "Testingu2120" (along with UTF coed u2120)comes as a string as part of SOAP response. I need to convert this UTF-8 characters in to a symbol, in this case it is SM (Service Mark) symbol and show it on the UI.
How can we achieve this in JAVA?
I have four different UTF-8 character set to convert.
I would like my application to execute a command in cmd. The command looks like
start "" /D "C:Riot GamesLeague of LegendsRADSsolutionslol_game_client_sln elease s .0.1.55deploy" "League of Legends.exe" "8394" "LoLLauncher.exe" "" "spectator 95.172.65.26:8088 P3hNrXYZlaM3iJ9ximtzJWHbwLhvbimJ 953089676 EUN1"
So my question is how do I do this?
I tried this, (just copy paste the command):
package MyProject; import java.io.IOException; import java.io.InputStream; public class Cmd { public static void main(String[] args) { try { final Process process = Runtime.getRuntime().exec("start "" /D "C:Riot GamesLeague of
We started learning about tables and have a little program. The teacher gave us an excercise and doesn't works (not running), I receive too many errors. So any simple java program with tables with 20 numbers, that is giving random numbers?
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 have to create a new project in which i have to take the inputs from the user and create the XML schema out of this. How can I do this the best way .
