Help needed turning this program into 2-class and demo.. plz help

Posted: Oct 15, 2009 7:12 AM

import java.util.Scanner;

public class StateA
{
public static void main (String[]args)
{
String input;

Scanner keyboard = new Scanner(System.in);

System.out.println("Please enter one of the following state abbreviations: ");
System.out.println("NC, SC, GA, FL, or AL");
input = keyboard.nextLine();

if (input.equalsIgnoreCase("NC"))
{
System.out.println("You've entered the abbreviation for North Carolina");
}
else if (input.equalsIgnoreCase("SC"))
{
System.out.println("You've entered the abbreviation for South Carolina");
}
else if (input.equalsIgnoreCase("GA"))
{
System.out.println("You've entered the abbreviation for Georgia");
}
else if (input.equalsIgnoreCase("FL"))
{
System.out.println("You've entered the abbreviation for Florida");
}
else if (input.equalsIgnoreCase("AL"))
{
System.out.println("You've entered the abbreviation for AlabamaA");
}
else
{
System.out.println("That's not a choice.");
}
}
}

Also, when you make a UML diagram, do you do it for the class or demo - or both?

Okay, I have the DEMO, it works:

import java.util.Scanner;

public class StateAbbreviationsDemo
{
public static void main(String[]args)
{
String yourinput;

Scanner keyboard = new Scanner(System.in);

System.out.println("Please enter one of the following state abbreviations: ");
System.out.println("NC,SC, GA, FL, or AL");
yourinput = keyboard.nextLine();

StateAbbreviations states = new StateAbbreviations(yourinput);

System.out.println("You have entered the abbreviation for " + states.getSOMETHING);
}
}

this is the other half i have so far:

public class StateAbbreviations
{
private String input;

public StateAbbreviations(String i);
{
input = i;
}

public String getInput()
{
if (input.equalsIgnoreCase("NC"))
{

}
}

Trying to use these two programs as a guideline to write the StateAbbreviations programs:

SOFTWARE SALES:

public class SoftwareSales
{
private final double UNIT_PRICE = 99;
private int unitsSold;

public SoftwareSales(int u)
{
unitsSold = u;
}

public int getUnitsSold()
{
return unitsSold;
}

public double getDiscount()
{
double discountPercent;
double discount;

if (unitsSold >= 100)
{
discountPercent = 0.5;
}
else if(unitsSold < 100 && unitsSold >= 50)
{
discountPercent = 0.4;
}
else if(unitsSold < 50 && unitsSold >= 20)
{
discountPercent = 0.3;
}
else if(unitsSold < 20 && unitsSold >= 10)
{
discountPercent = 0.2;
}
else
{
discountPercent = 0;
}

discount = (unitsSold*UNIT_PRICE) * discountPercent;
return discount;
}

public double getCost()
{
double cost = (unitsSold*UNIT_PRICE) - getDiscount();
return cost;
}

}

---------------------------------------------------

SOFTWARE SALES DEMO

import java.util.Scanner;
import java.text.DecimalFormat;

public class SoftwareSalesDemo
{
public static void main(String[] args)
{

int units;

Scanner keyboard = new Scanner(System.in);

System.out.println("Enter the units sold: ");
units = keyboard.nextInt();

SoftwareSales sales = new SoftwareSales(units);

DecimalFormat formatter = new DecimalFormat("#,##0.00");

System.out.println("Units sold: " + formatter.format(sales.getUnitsSold()));
System.out.println("Discount: " + formatter.format(sales.getDiscount()));
System.out.println("Cost: " + formatter.format(sales.getCost()));
}
}

This is finished i guess, i can compile successfully but my office computer wont run -- ... so.. idk...

i can't run it
won't know if it's really done

here it is:

public class StateAbbreviations
{
private String input;

public StateAbbreviations(String i);
{
input = i;
}

public String getInput()
{
if (input.equalsIgnoreCase("NC"))
{
input = "North Carolina";
return input;
}

else if (input.equalsIgnoreCase("SC"))
{
input = "South Carolina";
return input;
}
else if (input.equalsIgnoreCase("GA"))
{
input = "Georgia";
return input;
}
else if (input.equalsIgnoreCase("FL"))
{
input = "Florida";
return input;
}
else if (input.equalsIgnoreCase("AL"))
{
input = "Alabama";
return input;
}
else
{
System.out.println("That's not a choice.");
}
}
}
