I am trying to write a code for a game HiLo, where i want to add 3 different levels:
easy (1-10)
medium (1-100)
hard(1-1000)
Where the user can choose before the game starts. After that the game is finished i want even to write how many guesses the player used on the screen.
I have several Windows 7 Enterprise machines that have already been deployed via image and need to lower the security settings for use on internal web based applications.
Is there an easy way to manipulate the configuration (a file) so that I may simply make the changes by overwriting the current configuration settings instead of, having to go to each device, opening the Java console, and changing the security settings that way?
I have attempted to login as the machine administration, make the changes on the Java console with the hopes this configuration would have migrated to all user profiles that log into the PC. Is there a "public profile" configuration file I can change and if so, what should I do.
I am a beginning programmer and was learning how to make an XML. It was for a simple game and only needs to hold the highscores of three different levels. Here is what I coded:
try {
OutputStream fout= new FileOutputStream("highScores.xml");
OutputStream bout= new BufferedOutputStream(fout);
OutputStreamWriter out = new OutputStreamWriter(bout, "8859_1");
[code]....
My issue is that I run this code every time I create the program and the scores are reset to 0. How can I make a small change so that I only run this block of code and create the XML the first time the program is run?
I will try to explain what i want to code , a HiLo game where the user can choose up to 3 different levels(1-10, 1-100, 1-1000) with these 3 methods
public static void main(String[] args) {...}
public static int playGame(int maxNumber) {...}
public static void giveResponse(int answer, int guess) {...}
with no Random , i will use the:
int number = (int)(Math.random() * max) +1; to generate numbers
I have tried so many times , but i don't get it ....
My code so far :
import java.util.Scanner;
public class HL{
public static void main(String[] args ){
Scanner s = new Scanner(System.in);

In the class below I'm trying to create a class that will accept dates in various formats and create a range. The first constructor is easy because I send it the begin date and end date as Date objects. Now I want to send a month(and year) in a constructor and derive the begin and end dates from it. In my constructor that accepts the month/year I need to put the this(startDate, endDate) at the top to be allowed, but the parameters are not built yet.
package com.scg.athrowaway;
import java.util.Calendar;
import java.util.Date;
public class DateRange {
private Date startDate;

I'm new to Java and I have an assignment to create a Sphere class that will allow you to create Sphere objects using the code below. Then create a program called SphereTester that prompts the user for the radii of two spheres in meters. The program should display which sphere is larger and by how many cubic meters and display only four digits after the decimal point. I have the sphere class given to us for the assignment which is this:
Java Code: public class Sphere {
// instance variable (i.e., a field)
private double radius;
// constructor for the Sphere class
public Sphere(double r) {
radius = r;

create a jar file.Currently I have next files in my directory:
Manifest.txt:
-------------
Manifest-Version: 1.0
Created-By: 1.7.0_60-ea (Oracle Corporation)
Main-Class: connectURL
connectURL.class
------------------
it compiled fine, can be executed as:
java connectURL
it does not have 'Package' specified
sqljdbc4.jar
-----------
This is jdbc 4 jar file which is used by connectURL.java to make db. connection.
I am running:
C:j>jar cvfm connectURL.jar Manifest.txt *.class sqljdbc4.jar
added manifest
adding: connectURL.class(in = 2427) (out= 1358)(deflated 44%)
adding: sqljdbc4.jar(in = 584207) (out= 549364)(deflated 5%)
Then trying to execute and get error message
C:j>java -jar connectURL E520 1433
Error: Unable to access jarfile connectURL
how to create a JAR File I have been watching you tube and it seems like the manifest needs to be remade. I go to the CMD and find my project folder class. I think I need to use do the same for all the classes correct. Well I type jar -cf TictacToeGUIGame.jar *java then I get no such directory. I can see the it worked thought. So do i do this to all my classes and then I will have my JAR program?
