import java.io.*;

public class SpeedCam
{
	private static final String FILE_SPEC0 = "C://camera0_test1.dat";
	private static final String FILE_SPEC1 = "C://camera0_test2.dat";
	private static final int SPEED_LIMIT = 50;

	public static void processData()
	{
		FileInputStream fis;
		DataInputStream dis;
		FileOutputStream fos;
		DataOutputStream dos;
		String regNum;
		int Time1;
		int Time2;
		int Time3;
		String VehicleType;
		
		try
		{
			fis = new FileInputStream(FILE_SPEC0);
			dis = new DataInputStream(fis);
			fos = new FileOutputStream(FILE_SPEC1);
			dos = new DataOutputStream(fos);

			while(true)
			{
				try
				{
					regNum = dis.readUTF();
					Time1 = dis.readInt();
					Time2 = dis.readInt();
					Time3 = dis.readInt();
					VehicleType = dis.readUTF();
					System.out.print(regNum+"\t"+Time1+"\t"+Time2+"\t"+Time3+"\t"+VehicleType);
					
				}
				catch(Exception e)
				{
					fis.close();
					fos.close();
				}
			}
		}
		catch(Exception e)
		{
		}
	}

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

I don't have even the vaugest idea what's wrong with this, but its flat out refusing to print. The file exists, and supposedly contains relevant information, although i can't confirm this. Does anyone have enough experience to be able to guide me down the right path so i can get started on this application

Spoiler for Story of My life:
Quote:I'm 20 and I was a computer/electrical engineer major. I was into my third year and I had a year and a half to go.

Then 1 day as I am doing my programming homework and figuring out what the hell was wrong with my code,

I thought to myself 'spoon, i don't want to do this for the rest of my life.'

So I changed majors and now I am a proud music (vocal) education major. The point is do what you want to do in life. Cause its your life don't let anyone hold you back.

RE: Help With Java
MOAR HALP TIEM!!!!


Im screwed. i can't make this program output index, and its absolutely killing me. Not supposed to fix any errors unless theyre syntax, so that's not what needs sorting...just a couple of lines to make it run

Anyone can help
Spoiler:
import java.util.Scanner;

public class Annex1 {
    private static String calcIndex(int gr, int wo, int con)
    {
String index = "";
boolean ok = true;
String index1;
String index2;
String index3;
if(gr < 1 || gr > 8)
{
    ok = false;
}
if(con < 1 || con > 4)
{
    ok = false;
}
if(!ok)
{
    index = "ZZZZ";
}
else
{
    index1 = g_value(gr);
    index2 = w_value(wo);
    index3 = r_value(con);
    index = index1 + index2 + index3;
}
return index.toString();
}
    
    
    private static String g_value(int gr)
    {
Integer i = new Integer(gr);
return i.toString();
    }

    private static String w_value(int wo)
    {
int val;
Integer i;
if(wo < 500)
{
    val = 0;
}
else if(wo ≤ 1000)
{
    val = 1;
}
else if(wo < 2500)
{
    val = 2;
}
else
{
    val = 4;
}
i = new Integer(val);
return i.toString();
    }

    private static String r_value(int con)
    {
Integer i = new Integer(con);
return i.toString();
    }
    


    
/**
* @param args
*/
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int gr = scanner.nextInt();
int con = scanner.nextInt();
int wo = scanner.nextInt();
calcIndex(gr,con,wo);
}

}

RE: Help With Java
Output, as in, display the result of calcIndex to the console?
If so, you should change

Java Code 
calcIndex(gr,con,wo);

to

Java Code 
System.out.println(calcIndex(gr,con,wo));

or whatever the proper Java functions are.
