View Replies View RelatedSo I'm trying to create a simple user database that I could eventually turn into a login system. I created a simple table on MySQL with a name and address for the sake of simplicity. I tried to create simple statement inside my main method that would connect to my MySQL server and when I run my program I get a ClassNotFoundException from "org.gjt.mm.mysql.Driver"..Here is what I have in my main method thus far:
public static void main(String args[]) {
try {
Class.forName("org.gjt.mm.mysql.Driver"); //Load the driver
Connection conn = DriverManager.getConnection("jdbc:mysql://localhost/data", "root", ""); //Connect
/*
conn.createStatement().execute("CREATE TABLE people (" + "id int(64) NOT NULL AUTO_INCREMENT," + "name varchar(255) NOT NULL," + "address varchar(255) NOT NULL," + "UNIQUE (id)," + "FULLTEXT(name, address))");

I downloaded Connector/J in the the binary .zip form and extracted it to my C: drive and put the .jar file into my java directories lib folder. I also added the directory of the .jar file into my CLASSPATH and I still get the exception.
I have it all working great, but my professor is expecting a different output. He wants a box where you select your dormitory and meal plan, with "Calculate charges" and "Exit" buttons. When you click "Calculate charges," a second box comes up with a message with your total charges. I've tried other stuff like:
JOptionPane.showMessageDialog(total,
"Total Charges For the Semester: ");

i am studying java from head first java book and yesterday i was working on a program called QuizCardBuilder. what i noticed is that when i changed the order of the lines from the book i get a blank frame with nothing on it.this is my code that gives blank frame

JFrame frame;
JTextArea question;
JTextArea answer;

So my code works perfectly when I input (a+(c-d) and i get ab+cd- for postfix and *+ab-cd for prefix. However when I input a+b+c for infix i receive abc++ postfix and +a+bc prefix when its supposed to be ab+c+ postfix and ++a b c prefix. So my issue is that any infix input with parenthesis, it converts them correctly, however without parenthesis it does not convert correctly.
import java.util.*;
public class stack {
public static char[] convertToPostfix(char[] infixEx) {
Stack<Character> operatorStack = new Stack<Character>();
char[] postfix = new char[infixEx.length];
int index = 0;

I have the Java Development Kit downloaded in my C file and my book tells me to compile the program I need to open command windowand change the directory where the program is stored. I tried the command cd to change directory and received this message "The system cannot find the path specified."
I checked the Environment Variables on Windows 7 and the Path says: C:Program Files (x86)Javajre1.8.0_31in
This is after many tries and i still can't change directory and i keep getting the same message.
I'm making a stock system for the heck of it,so everything was going great until I hit the loop I am trying to use a for loop to add stock to the stock system,any way the question is maily about loops.How come I cannot declare a variable outside a loop and assign a value to it,for example I can declare as follows and I will not get an error,
for(int i=0;i<10;i++){
System.out.println("example");
}
but in my code(and yes its the only error I get I tested it) I get an error and can only declare and assign a value inside the loop,the reason for this is because I wanted to get the value from another class and use it in the loop ok so heres the code from both classes.
public class mainn{
public static void main(String [] args){
stock first = new stock();
int internal;
internal = first.wanted;

I'm assigned along with two others to make this program for a project.
We need to store data to the program by adding them such as user_id among the 5 criterias that are needed. Lets say I want a new user, I need the program to give me that option and then I would type in the user id and the program would store that data information
As far as I'm aware, boolean, screentokenizer and scanner is involved in the making of this program.
In my java program I'm changing my IP(using proxy) and sending the request to some sites. Later some point of time, I want to know my current IP address through java program itself. How to get hold of my current IP address? Also which IP address will it show? The proxy one or the original IP ?

90-Point Version Specifics: The 90-point version requires that you write both the fromHexToBin and fromBinToDec methods.
90-Point Version Output
95-Point Version Specifics {The 95-point version requires everything from the 90-point version and adds the fromBinToHex method. For this version, you may assume that the binary number will have a multiple of 4 bits.
95-Point Version Output
100-Point Version Specifics: The 100-point version requires the same methods as the 95-point version; however, the fromBinToHex method needs to be improved so it can convert regardless of the number of bits.
100-Point Version Output
105-Point Version Specifics: The 105-point version requires everything from the 100-point version and adds the fromDecToAny method. For this version, the method needs to be able to convert from decimal to any base between 2 and 10. Base 16 is not required for this version.
105-Point Version Output
110-Point Version Specifics: The 110-point version requires the same methods as the 105-point version; however, the fromDecToAny method needs to be improved so it can also convert to base-16.
I'm in the middle of building A time management system for myself.I'm currently using JodaTime for timing in java. I just can't figure out who to save my data like, the starttime, stoptime and day time.

PreparedStatement checkStmt = con.prepareStatement(checkSql);
String insertSql = "insert into Time (id, day, starttime, stoptime, overtime, exception, hours) values (?, ?, ?, ?, ?, ?, ?)";

String updateSql = "update Time set day=?, starttime=?, stoptime=?, overtime=?, exception=?, hours=? where id=?";

I am going to try and write a server-client based system.The server will be the design of what I want (e.g: daily advertisements that will be displayed on big monitors connected to the client, with like a slideshow looping). The client will just be receiving information from the server and not doing anything with it except displaying it and perhaps a networking element of the client reporting back to the server if the connection is dropped etc. The administrator can use the server to change the look of the advertisement.
I need the server to PUSH OUT to the client computers.I am on a networking degree so there has to be some elements to networking connections going on and programming is not my strong point. Would I write the server and clients in Java or another program? Will there need to be a "middle" program such as a web server?
Ok so this is a grading program. I have it so the user can input 2 students and then at the end using an if statement it is suppose to compare them and print out who had the higher grade. Seems simple but it never runs the line of code to print out whos grade is higher:
if (stuAverage > stuAverage2 ){
System.out.println(student + " has the highest grade of all students entered!");
}
else if (stuAverage2> stuAverage){
System.out.println(student2 + " has the highest grade of all students entered!!");
}
Here is the Main class:

I have been working on making a Java application for the Game RuneScape. My goal is to make an Application to where you register on the application and it saves the information in a file. I am also looking to make it so you can transfer money from Runescape to your Account on my Application by submitting a ticket. When you submit a ticket you get assisted by one of the moderators, they trade you in the game and take the money, and then they take that money out of their current account. Admins are allowed to give moderators money via their account or another method. My issue is creating the ticket system. I want to be able to do this all via the application. So basically what i have currently for the application is a chat room, with different rooms available to go into by the users. So I need to make the tickets show up only to Moderators and Admins in the general chat room.
View Replies View RelatedI am quite new to java and trying to print all the system properties with the following
code:System.out.println(System.getProperties());
This prints all the properties as expected but I am wanting to put each property on a new line and am struggling a bit. Obviously I will need some sort of for loop etc but im just not sure how to do it. Is it something along the lines of:
for (int i = 0; i < System.getProperties().size(); i++){
What my understanding of what the above is doing is checking how many properties there are an looping round for each property that exists, so all I need to do is get the property 1 at a time however I am not sure where to get the property value to input into the System.getProperty(); method.
I am in search of a library that has been created in JAVA that can be utilized to solve for roots of a nonlinear system of equations. Each equation has 2 variables, x and y, and will need a library that uses higher calculus equations. No ones that just solve for x.
Most of the libraries that have been created to solve nonlinear equations are either in Fortran, C, or Python. There are a few libraries such minpack/scipy. The only libraries that I have been able to find or programming solutions that are in JAVA either require additional programs such as Matlab or are commercial products
I did find one library put together by a professor in Colorado State, but am unsure how to use it. There does not seem to be a way to enter your functions in the code.

How to use this library or find a library that can be used in an android application would be amazing.
