Help with java homework....

[Rick Alvernaz]

Can someone please look at this, I'm sure I'm just missing something really easy. Something is wrong with my Method. I'm brand new to java, so don't laugh.

I realize you can't see everything...put maybe someone can spot the problem real quick.

public class SpacelySprockets
{

	public static void main(String[] args) //Main Program
	{  //Start Main


		int partNumber=0;
		int quantity=0;
		int part1Total=0;
		int part2Total=0;
		int part3Total=0;
		int part4Total=0;
		int part5Total=0;

		Keyboard kbd;
		kbd = new Keyboard ();

		InputFile sprockets;
		sprockets = new InputFile ("E:\\MaxSync\\School\\SLCC\\CIS 1030\\Spacely Sprockets\\sprockets.txt");

		while (!sprockets.eof())
		{   //Start Loop

			partNumber=sprockets.readInt ();
			quantity=sprockets.readInt ();


			switch (partNumber)
			{
				case 1:		part1Total = part1Total + quantity;
							break;
				case 2:		part2Total = part2Total + quantity;
							break;
				case 3:		part3Total = part3Total + quantity;
							break;
				case 4:		part4Total = part4Total + quantity;
							break;
				case 5:		part5Total = part5Total + quantity;
							break;
				default:	System.out.println ("The file has unknown part numbers ltstd");
			}


		}   //End Loop

		detailLine (part1Total, 1);
		detailLine (part2Total, 2);
		detailLine (part3Total, 3);
		detailLine (part4Total, 4);
		detailLine (part5Total, 5);


	}  //End Main

	public static void detailLine (int partTotal, int partNumber);
	{
		OutputFile summaryReport;
		summaryReport = new OutputFile ("E:\\MaxSync\\School\\SLCC\\CIS 1030\\Spacely Sprockets\\summaryReport.txt");

		summaryReport.writeWord (partTotal, partNumber);
		summaryReport.writeEOL();
		summaryReport.close();

	}


} //End Class

What exactly is wrong?

It is very hard to read code written by someone else. Tell us what it is supposed to do and what really happens.

 

[Rick Alvernaz]

Sorry, I should have given more information.

The program is supposed to read a text file that contains information like below....

1 99
2 88
3 77
4 66
5 55
1 10
2 35
5 50
3 60

It supposed to add up the numbers on the right, corresponding with the numbers on the left and right that information to a file. For example there are 105 "5"s and 123 "2"s.

So the new file should look like this

1 109
2 123
3 137
4 66
5 105

However,

When I compile my program...I get this error.

3 errors

Tool completed with exit code 1

I've also tried using writeWord, writeInt, and writeString.

Remove the semicolon from the end of line 56 (public static void detailLine...).

You seem to be using some course-specific classes (Keyboard, InputFile, OutputFile), so I can't verify the correctness of the program..

 

[Rick Alvernaz]

wow, I feel stupid. I can't believe I spent so much time over one semicolon. I knew it would be something simple.

I got the programing running now. Thanks for your help.
