Im looking for some guidance as to how i would go about moving implemenation out of main(String[ ] args). I have tried to do this a few times and all i seem to do is mess up my code.

public class Dvdinventory { public static void main(String args []) { DVD dvd; dvd = new DVD(1, "The Unit", 1, 24.95); System.out.println(dvd); dvd = new DVD(2, "The Color Purple", 1, 18.99); System.out.println(dvd); dvd = new DVD(3, "The Bucket List", 1, 19.99); System.out.println(dvd); dvd = new DVD(4, "Hancock", 1, 19.99); System.out.println(dvd); } //end main } // end class Dvdinventory class DVD { private int dvdItem; private String dvdTitle; private int dvdStock; private double dvdPrice; public DVD(int item, String title, int stock, double price) { dvdItem = item; dvdTitle = title; dvdStock = stock; dvdPrice = price; } //end four-argument constructor // set DVD Item public void setDvdItem(int item) { dvdItem = item; } //end method set Dvd Item //return DVD Item public int getDvdItem() { return dvdItem; } //end method get Dvd Item //set DVD Title public void setDvdTitle(String title) { dvdTitle = title; } //end method set Dvd Title //return Dvd Title public String getDvdTitle() { return dvdTitle; } //end method get Dvd Title public void setDvdStock(int stock) { dvdStock = stock; } //end method set Dvd Stock //return dvd Stock public int getDvdStock() { return dvdStock; } //end method get Dvd Stock public void setDvdPrice(double price) { dvdPrice = price; } //end method setdvdPrice //return DVD Price public double getDvdPrice() { return dvdPrice; } //end method get Dvd Price //calculate inventory value public double value() { return dvdPrice * dvdStock; } //end method value public String toString() { return String.format("item=%3d title=%-20s units=%d price=%.2f value=%.2f", dvdItem, dvdTitle, dvdStock, dvdPrice, value()); } } //end class DVD

Im using txtpad so i not sure

Have you got a text editor which supports syntax highlighting?

However i have managed to get less errors . Im just not sure if im making progress or moving backwards

import java.util.Scanner; // This program uses class Scanner public class Payroll { public Payroll() { //create a scanner object to obtain input from command window Scanner input = new Scanner(System.in); String employeeName = ""; //input employee name double hourlyWage; double hoursWorked; double weeklyPay; // loop until the user enters 'stop' as the name of the employee. do { // Get Employee Name System.out.print("Enter Name of Employee:"); employeeName = input.next(); // if the employee name is 'stop', then exit the loop. if (employeeName.equals("stop")) { break; } // ask for hourly wage System.out.print("Enter hourly Wage:"); hourlyWage = input.nextDouble(); // require that the hourly wage is a non-negative while (hourlyWage < 0.0) { System.out.print("Hourly wage must be a positive number. Please enter a positive hourly wage:");//prompt hourlyWage = input.nextDouble(); input.nextLine(); } // ask the hours worked System.out.print("Enter hours worked:"); hoursWorked = input.nextDouble(); // require that hours worked be a non-negative number while (hoursWorked < 0.0) { System.out.print("Hours worked must be a positive number. Please enter a positive number of hours:");//prompt hoursWorked=input.nextDouble(); input.nextLine(); } weeklyPay = hourlyWage * hoursWorked; System.out.printf("The employee, %s, was paid $ %.2f this week.\n\n", employeeName, weeklyPay); } while (true); } } public static void main(String args[]) { new Payroll(); } //end method main //end class Payroll public class Employee { public Employee() { String name; int hoursworked; int hourlywage; int weeklyPay; } Employee employee = new Employee(employeeName, hourlyWage, hoursWorked); public Employee(String name, int hours, int rate) { this.name = name; this.hoursworked = hours; hourlywage = rate; computeWeeklyPay(); } private void computeWeeklyPay() { weeklyPay = hoursworked * hourlywage; } public int getWeeklyPay() { return weeklyPay; }

The error i recieved was ..

Payroll.java:92: reached end of file while parsing

In the midst of writing the code for my java program, i have seem to taken a misturn somewhere. Any advise or sugestions on what i can do to correct this is much needed. It works good until i get to the employee class near the bottom.

import java.util.Scanner; // This program uses class Scanner

public class Payroll {

public Payroll() {

//create a scanner object to obtain input from command window
Scanner input = new Scanner(System.in);

String employeeName = ""; //input employee name
double hourlyWage;
double hoursWorked;
double weeklyPay;

// loop until the user enters 'stop' as the name of the employee.
do {

// Get Employee Name
System.out.print("Enter Name of Employee:");
employeeName = input.next();
// if the employee name is 'stop', then exit the loop.
if (employeeName.equals("stop")) {
break;

}

// ask for hourly wage
System.out.print("Enter hourly Wage:");
hourlyWage = input.nextDouble();
// require that the hourly wage is a non-negative
while (hourlyWage < 0.0)
{
System.out.print("Hourly wage must be a positive number. Please enter a positive hourly wage:");//prompt
hourlyWage = input.nextDouble();
input.nextLine();

}

// ask the hours worked
System.out.print("Enter hours worked:");
hoursWorked = input.nextDouble();
// require that hours worked be a non-negative number
while (hoursWorked < 0.0)
{
System.out.print("Hours worked must be a positive number. Please enter a positive number of hours:");//prompt
hoursWorked=input.nextDouble();

input.nextLine();
}


weeklyPay = hourlyWage * hoursWorked;
System.out.printf("The employee, %s, was paid $ %.2f this week.\n\n", employeeName, weeklyPay);

} while (true);


}
} public static void main(String args[]) {
new Payroll();

} //end method main

//end class Payroll



public class Employee {

public Employee() {

String name;
int hoursworked;
int hourlywage;
int weeklyPay;

public Employee(String name, int hours, int rate) {
this.name = name;
this.hoursworked = hours;
hourlywage = rate;
computeWeeklyPay();
}

private void computeWeeklyPay() {
weeklyPay = hoursworked * hourlywage;
}

public int getWeeklyPay() {
return weeklyPay;
}
;

anyone know where i can find some very basic examples of how to add a second method to existing code

Thank you very much its almost sickening that the misplacement of brackets can turn into a nightmare

Thanks for the help i will give it another shot ad also take a look at the tutorial also

If you dont mind can you explain this a lil further im very new to this and atm this one project has me pulling out










import java.util.Scanner;


public class Payroll {

public Payroll() {

{
// create Scanner to obtain input from command window
Scanner input = new Scanner( System.in );




// prompt for and input employee name
System.out.println( "Please enter the employee name:" );
String employeeName = input.nextLine(); // read a line of text
System.out.println(); // outputs a blank line

// prompt for and input employee hourly wage
System.out.println( "Please enter the employee hourly wage:" );
double hourlyWage = input.nextDouble(); // read a line of text
System.out.println(); // outputs a blank line

// prompt for and input employee hours worked
System.out.println( "Please enter the employee hours worked:" );
double hoursWorked = input.nextDouble(); // read a line of text
System.out.println(); // outputs a blank line


System.out.println(); // outputs a blank line

System.out.println("Employee Name: " + employeeName);
System.out.println("Hourly Wage: " + hourlyWage);
System.out.println("Hours Worked: " + hourlyWage);



public void static main(String[] args){)
new Payroll();



// end method main


// end class Payroll

I seem to be getting this error message now after i figured out why it wasnt running.Any ideas or suggestions on how to correct this?

my assignment called for me to Move implemenation out of main(String[ ] args). I thought this was what i was doing but it isnt i guess. Do you know where i might could look for information or ideas on how to accomplish this and my code still runs.

Thank you all for the much needed help. I read more on how packages from both sites that was listed by you guys.So now my error is gone Yay but my program fails to run even though it gives no errors.Any suggestions on why this might be happening?

I guess im a lil confused because i have the class files in the same directory which is the bin folder. Is this a bad idea?

I have been working on trying to get a project to run for 2 days but i receive the following error.Let me backup a lil. This is what my code looks like. I had no errors until my assignment called for me to Move implemenation out of main(String[ ] args). Any help or suggestions will be much appreciated.

I tryed adding one and still somehow manage to get that error.. So i must be having a lack of brain function moment.. Any help with this will be much appreciated
