I have a very basic question about the Maven. I compile 2 dependent projects on maven and they have a problem, then I change a code and I recompile the project.
After that in the jar file of this project, I see that the code is the same, the error also shows me that the file is the same ( from the error line i can understand that) ....
import java.io.InputStreamReader;
import java.util.Scanner;
public class FinalCombinations {
public static void main(String[] args){
//Read number of values
System.out.println("Enter the no of values");
[Code] .....
I am getting output like this
Enter the no of values
4
Enter the values
1

4
Enter the number for combination

C(4,2)=6

I have a major problem. the text size is like 6 or 8 pt font and I can't read it. I'm trying to run a downloaded exe program which uses the jre7 which I had to download beforehand. the font size stays at 6 or 8 even if I try to change it in windows settings. it's a high res monitor on a lenovo yoga laptop. is there a way for me to edit the java code and manually change the font size?

So I don't know whether this is an issue with my decompiler or my IDE. I have a jar game that is written/compiled in JDK 1.1 (45.3)
Now when I use a dissasembler and export the class I want to change to a .java(source) file I can edit it fine and dandy with BlueJ. The only problem is IT WONT RECOMPILE
Now this is completely odd I thought it might be that I changed something I wasn't supposed to so I tried it again on a fresh rip of the .java file. IT STILL WONT RECOMPILE
I'm not sure exactly what the problem is, whether the .class is getting truncated/changed when exported to .java OR whether my decompiler is funky... But it makes absolutely no sense that you can decompile an already existing .class file RECOMPILE it exactly UNCHANGED and it fails to recompile....
I only want to change a few lines so that the jar im using can use a touchscreen...
When I write below command:
which mvn
I see below output
/usr/bin/mvn
But it is not the maven installed by me. I think it came with linux
Now I want to change mvn path with following command:
export M2_HOME=/usr/local/apache-maven/apache-maven-2.2.1
export M2=%M2_HOME%bin
But it does not change. I still see
which mvn
I see below output
/usr/bin/mvn
I have written a library in one project but cannot seem import to import it into my main project whenever I try Maven says it cant find it though it is installed in the repository and the .jar file is in the classpath.

While going through stpring batch,every where there uses pom.xml. But in my office maven repo is blocked. How to get the jar files .
Is there any way to run pom.xml online and download required jar to my local drive. or how to run a pom.xml file after setting maven, I had done all the same but some unknown issues.
In my project, .class files of servlets are absent, because of some configuration mistake.

I was a bit confused of the code generated by the Axis2 Code Gen.
I have created a logIn(String username, String password) method in my service and used Axis2 Code Gen to generate the Stub.
I try to access the logIn method from my Client using the Stub like below:
TestServiceStub stub = new TestServiceStub("http://localhost:8080/axis2/services/TestService");
String test = stub.logIn("user","pass").
but instead of UserName and password as the parameters, the Stub created a Login object as the parameter for the logIn method. like the one below:
stub.logIn(Login login1);
I wanted to try the logIn method by providing a static userName and password but it seems impossible because the Stub changed the parameter for the logIn method.
how to test the logIn method.
The code here I have works fine if I just want to ask the user to enter four digits: //java application that asks user to input binary numbers(1 or 0) and convert them to decimal numbers import java.util.Scanner; //program uses class scanner public class binarynumber{
//main method that executes the java application
public static void main(String args[]){
//declares variables
int digit;
int base=2;
int degree;
double decimal;
int binary_zero=0;
int binary_one=1;
//create scanner for object input
[code]....
The thing is, I want the java application to input more than four digits for the user and I want it to loop it manytimes f until the user ask it to stop.
I need to create a Java program that takes an input a color code in HSV and outputs the equivalent RGB code and Vice versa.
Example:
If you test on the color RED in RGB:
Input: (255,0,0)
Output: (0,100%,100%)
If you test on the color RED in HSV:
Input0,100%,100%)
Output: (255,0,0)
I am currently working on Java software which resize jpeg images and change DPI also. For JPEG images having app0JFIF node it works fine and the images new DPI is reflected in Photoshop. But if app0JFIF node not exist, I am trying to create a new one and set the DPI value there. Everything is going proper but if I open these images in photoshop it does not reflect new DPI but the size changes.
Java Code:
double dpi_in_inch = 0.393701 * newres;
File file1 = new File(imgName);
image = ImageIO.read(file1);
int wd, hi;
wd = (int) (newsize * dpi_in_inch);

My understanding was I could override a method from the superclass, including with different parameters, but when I try to use super. it gives me an error the arguments have to match the superclass. But, if I do that it won't make any sense.
The first code below is the superclass. The issue I'm having is on the second code at lines 7 and 10. The ultimate goal is to make a new class where I'm able to display various packages with or without insurance.
public class Package {
double shippingWeight;
public char shippingMethod;
final char air = 'A';
final char truck = 'T';
final char mail = 'M';
double shippingCost;

I am having trouble doing a simple exercise changing a for loop to a while statement, it works fine in the for loop but in the while statement it just prints out 10(it is supposed to count to 0 and print liftoff).
public void run() {
int i = 10;
while (i>=1) {
println(+i+"...");
i--;
}
println("liftoff...");
}
I have a servlet with a method:
/**
* @return <code>double</code> Hours
*/
public double getDriveHours() {
return getAsDouble("DriveTime", 0.0D);
}
I would like to change the time to minutes. I will create a new entry in the db for the minutes, but wondered if the time minutes is also double.
I'd like to make a simple cheat for an old game that's offline... It has no type of anti-cheat and I'd like to make a program that changes how much money you have... I think the first thing I have to do is get the data address or something like that by using cheat engine... How do I do that? After that how do I start using that info in my program and then send back a new value? Are there any classes that I should be importing and what methods do I use to do this?

im making a javabean for stopwatch which works perfectly, but i want in the property descriptor format, so the user can change its format.
currently i have;
private String displayFormat = "MMMM d, yyyy h:mm:ss";
private SimpleDateFormat formatter;
public synchronized void setDisplayFormat(String newFormat) {
String oldFormat = getDisplayFormat();
try {
formatter.applyLocalizedPattern(newFormat);
timerHasPinged();

currently the timer works its format is in 00:00 minutes:seconds, but i want it to start as MMMM d, yyyy h:mm:ss, for example March 17 2014 00:00:01, so only one second has passed here. i believe the set and get format method is fine but the timerhaschanged needs to change as this is where the format takes place.

The Toys of the Future Company has decided to issue a new line of toy robots. While they are not sure exactly what their robots will look like, they do know the functionality that they will all have. All robots will be able to move forward, turn right, turn left, spin and detect an object in front of it via a sensor. The robot will use a touch sensor to determine whether it has hit an object in front of it, such as a wall. The robot will have two, three, or four wheels, but it will only be driven by two of them: a right wheel and a left wheel. Each wheel will be attached to a motor that controls it.
* ^ this is only something to think about
Produce a UML class diagram.
Using UML, describe the objects and classes that will be associated with this new toy. Either hand draw or use an appropriate UML creation tool to generate a UML design document for your Robot class. Create a set of classes that can be used to control the robot.
Develop your new class.
Create a new NetBeans project entitled, "Assignment_8_1" and develop your new class. Now, using the objects and classes that you have written, write a program for your robot that allows it to move in a large square. Allow your robot to run in a big two dimensional array and every time the robot encounters a square in your array, turn that square black.
So here is the code for the moving ball:
package ballapplet;
import java.awt.*;
import java.util.Formatter;
import javax.swing.*;
public class BallApplet extends JPanel {
private static final int BOX_WIDTH = 640;

I want to know how to change the color of an object, and how to move it in specific directions.
I'm having some trouble figuring out how to change the value of a variable that is passed into a class. I've tried just changing the variable, I've tried changing it by using the this.variable command, and I've even tried calling the setter class from within the class to change it, but it's still not working right. The first class is the one with Main in it and I just feed it some dummy data:
public class ExamConverter {
public static void main(String[] args) {
// TODO Auto-generated method stub
Age testAge = new Age();
[Code] .....
This is the other class to calculate the age the way we do it on psych tests - it might not be mathematically accurate, but it's what all the tables and such for raw to scaled score conversion are based on, so the math needs to be the same as opposed to "accurate" because of some months having 30 or 31 days, etc.
public class Age {
//==================Properties==================
// Variables for the test date and client date of birth
private int TestMonth;
private int TestDay;
private int TestYear;
private int ClientMonth;
private int ClientDay;
private int ClientYear;
[Code] ......
Based on this dummy data, the output is:
Test: 5/4/2014
DOB: 5/5/1971
Age Years: 43 Months: 0 Days: 0
However, it should be:
Test: 5/4/2014
DOB: 5/5/1971
Age Years: 42 Months: 11 Days: 29
I have a empty JList in which I hit a button LOAD DATA which should load all the data. but once I load data i try to fill in the List but I keep getting errors.
String[] aos = new String[itrList.size()];
itrList.toArray(aos);
//JList listFAIL = new JList(aos);
//list = new JList(itrList.toArray());
//list.removeAll();
list.setListData(aos);
JScrollPane s = new JScrollPane(list);
I have tried doing setListData and i get a error;
And if i do new Jlist it doesn't change the data.
The List does fill as i have a checker for that.
I am starting to learn java , If suppose we write a simple hello world program
class helloWorld
{
public static void main(String args[])
{
System.out.print("Hello World !");
}
}
And save this as test.java.Now after compiling it a helloWorld.class file is generated.But if we compile the same after adding "public" in front of 1st line, it throws error.
public class helloWorld
{
public static void main(String args[])
{
System.out.print("Hello World !");
}
}
but then changing the file name to the name of the class i.e. helloWorld.java, corrects the error.
I have been working on a program that is meant to use a class' instructions in a program to add a value to a variable, save it, and present it. This is my class

//METHODS
public Car(int carYearModel, String carMake)

Whenever I call the accelerate method, a value of 5 is to be added to the speed variable. But whenever I call accelerate, it doesn't increase! I just don't understand why not. I've tried different renditions of adding 5 to speed and it doesn't quite work. I don't get any errors when I compile, just runtime, when it doesn't add 5 to speed.
