Thread: Coding a beginner program and get run time error possible loss of precision

I'm working on an assignment that states this:

Modify the Week Two Java™ application using Java™ NetBeans™ IDE to meet these additional and changed business requirements:

The company has recently changed its total annual compensation policy to improve sales.
A salesperson will continue to earn a fixed salary of <Add salary figure from Week Two here>. The current sales target for every salesperson is < Add a target sales figure here (e.g. $120,000)>.
The sales incentive will only start when 80% of the sales target is met. The current commission is <Add percentage here> of total sales.
If a salesperson exceeds the sales target, the commission will increase based on an acceleration factor. The acceleration factor is <Add a number greater than 1 (e.g. 1.25)>.
The application should ask the user to enter annual sales, and it should display the total annual compensation.
The application should also display a table of potential total annual compensation that the salesperson could have earned, in $5000 increments above the salesperson’s annual sales, until it reaches 50% above the salesperson’s annual sales.


The Java™ application should also meet these technical requirements:

The application should have at least one class, in addition to the application’s controlling class.
The source code must demonstrate the use of conditional and looping structures.
There should be proper documentation in the source code.


So here is the code I have come up with, but I keep getting these errors:

Main.java:56: error: possible loss of precision
for (projSales=sales+5000;projSales <= maxSales; projSales +=5000)
^
required: int
found: double
Main.java:58: error: package system does not exist
system.out.println(projSales + "\t\t" + accel); "

 
class NewProgram
{
	public static void main (String[] args)
	{
		double salary; //salesperson's salary
		double sales; //sales amount for year
		double commission; // commission without incentives
		double incentive; //when incentive kicks in
		double accel; //commission accelerated factor
		double salesTarget; // is half the salary plus 10,000$
		double totalIncentiveEarned; //total made from incentive program
		double totalIncome; //salary + totalIncentiveEarned
		double maxSales;  //for the table to show 50 percent above the annual sales
 
		Scanner keyboard= new Scanner(System.in);
 
		//Enter Salary
		System.out.print("What is salesperon's fixed salary?");
		salary=keyboard.nextDouble();
 
		//Enter Salespersons  sales for year
		System.out.print("What was their sales for the year?");
		sales=keyboard.nextDouble();
 
 
			commission= sales * .05;
			salesTarget=(salary * .5);
			incentive=.8*salesTarget;
			accel=commission*1.5;
			int projSales;
 
 
		if (incentive >= 80% salesTarget)
		{
			accel=sales*1.5;
				System.out.println("Congrats you qualify for the new incentive program!");
				totalIncome=accel+salary;
				System.out.println("Your commission for the new program is " + accel);
				System.out.println("Your total income for the year is " + totalIncome);
		}
			else 
			{
				System.out.println("You did not qualify for the sales incentive program");
				System.out.println("Your total commission was" + commission);
				System.out.println("Your total income for the year is" + totalIncome);
			}
 
	System.out.print("Your potential earnings were");
		for (projSales=sales+5000;projSales <= maxSales; projSales +=5000)
		{
			system.out.println(projSales + "\t\t" + accel);
		}
 
		}
 
	}

I also cant figure out why the:

System.out.print("Your potential earnings were");
		for (projSales=sales+5000;projSales <= maxSales; projSales +=5000)
		{
			system.out.println(projSales + "\t\t" + accel);

wont export into table format, it increasing the originally entered sales amount by 5000 and showing the potential compensation

The problem with

system.out.println(projSales + "\t\t" + accel);

is that Java is case sensitive, and you must capitalize "System."

The Int/Double problem that you have is not something that should cause a runtime error, but still something to be aware of. The variable projSales is an int, which cannot record decimal values. The other numeric variables you use are doubles, which do. The compiler is warning you that when you do equations mixing the two, you can lose precision by having the int variable truncate decimal values. I would recommend changing the type of projSales to double.

Hope that helps!

[/COLOR]So I got all of it to work. Here is my next problem.

The code is set up that if the person has sales that total less than 80% of the target sale amount, then it will pop up saying "you did not qualify under the program."

The incentives kick in when the person reaches 80% of the sales target, outlined in this part of the code:

commission= sales * .05;
			salesTarget=(salary * .5);
			incentive=.8*salesTarget;
			accel=commission*1.5;
			int projSales;
 
 
		if (incentive >= 80% salesTarget)
		{
			accel=sales*1.5;
				System.out.println("Congrats you qualify for the new incentive program!");
				totalIncome=accel+salary;
				System.out.println("Your commission for the new program is " + accel);
				System.out.println("Your total income for the year is " + totalIncome);
		}
			else 
			{
				System.out.println("You did not qualify for the sales incentive program");
				System.out.println("Your total commission was" + commission);
				System.out.println("Your total income for the year is" + totalIncome);
			}

however, no matter if the number is less than 80% or greater than 80%, the code is still outputting CONGRATS you qualify.

Shouldnt the else statement be kicking any number totalling less than 80% of the sales target to say not qualified? What am I missing?[COLOR="Silver"]

So I have double incentive=.8*salesTarget; set earlier in the code, but then for the if statement am trying to say if incentive is greater than 80% of salesTarget, do the rest of code. How would I put that in the code correctly lol
