Java Talk

Marcello asked:


I know enough Java to run many very simple programs and really just learning the basics of GUI. I want to program a piece of software for basic bookkeeping as a project to practice learning more java and I am wondering what you would recommend I do (or where to begin).

I have thought about the finding some existing bookkeeping programs and just manipulating them to what I am trying to accomplish but I also wonder if I would be better off (from a learning perspective) building something from scratch. The program on overall won’t be too complex but will include some input and outputting features and probably a download to excel component.

All help is appreciated.

Thanks.

Okay, I have a notepad item on my desktop called “Powers_of_i.java” It contains the following code that (in a GUI) simply calculates the values of imaginary numbers. How can I:
A) Run this program without using Eclipse (which I made it with)?
B) Send this program to someone else so they can use it?
Thanks for helping - please try to give me easy step-by-step instructions that I might be able to understand.
Sorry - I forgot to mention that the program is written in Java.

I have an assignment to create a NON-GUI based java application that calculates weekly pay for an employee. The application should display text that requests the user input the name of the employee, the hourly rate, and the number of hours worked for that week. The application should then print out the name of the employee and the weekly pay amount. In the printout, display the dollar symbol ($) to the left of the weekly pay amount and format the weekly pay amount to display currency.

I will add an additional comment to show what I have so far. Please help as i am stuck.
Thanks
// PayrollProgram.java
// Payroll Program that displays calculates weekly pay for an employee

import java.util.Scanner; // program uses class Scanner
public class PayrollProgram {

// main method begins execution of Java application
public static void main(String[] args) {
// create Scanner to obtain input from command window
Scanner input = new Scanner( System.in );

String name; // first name to be entered
String name2; // last name to be entered
int hourly; // hourly rate to be entered
int hours; // number of hours worked to be entered
}

}

And I am a novice one. I only know basis on java programming and the likes of “hello world” applications. Our professor basically cannot teach his students right.
How can I connect my java application to a database? Is there a GUI based program that could be used in order for easier making of my application? Can anyone tell me what it is? Any would do as long as my program stick to command prompts and java applets. Please can someone help….
Thanks in advance…

Justa_Mom asked:


had to write a non-GUI based java application that calculates weekly pay for an employee…this is what i have below….now I have to modify this so that the application continues to request employee information until the user enters stop as the employee name. In addition I have to program the application to check that the hourly rate and number of hours worked are positive numbers. If either the hourly rate or the number of hours worked is not a positive value, the application should prompt the user to enter a positive amount. I have the code below and now my instructor says that I need to utilize decision making controls such as “if” instead of try/catch..he says they aren’t doing me any good in the code. He also says Do I have all of the major components of a class in the code and does it perform the requested functionality of the assignment. I thought it did but obviously i’m wrong…can anyone help me modify this code please.

System.out.print(”Enter employee name: “);
try {
employee = br.readLine();
while (employee.equals(”"))
{

System.out.println(”Please enter proper Employeename:”);
employee = br.readLine();
if ( employee.equals(”") )
{
continue;
}
break;
}
catch (IOException ioe) {
System.out.println(”IO error reading employee name.”);
System.exit(1);
}

on similar foundation you can prompt user to enter
hourly rate and number of hours worked are positive numbers

try {
hours_str = br.readLine();
if(hours_str<0){
System.out.println("Please enter positive number of hours");
}
}

I am translating a command based program to a GUI I am building. Does anyone know of a simple JPanel style component I can sent toString() -type methods to and have them pop up in a separate GUI frame?
