Never mind. I figured it out. Apparently I need the source file to be in the
project folder and not the source folder. Although that's weird because it use
to work fine when the source file was in the source folder.

Subject: Eclipse compulation problem
I made a program that inputs information from one file and outputs it to
another file. I am able to run it perfectly with the java console from the
command prompt, But when I try to run it with Eclipse, I get the following
error.
Exception in thread "main" java.io.FileNotFoundException: History.d1 (The
system cannot find the file specified)
at java.io.FileInputStream.open(Native Method)
at java.io.FileInputStream.<init>(Unknown Source)
at java.io.FileInputStream.<init>(Unknown Source)
at java.io.FileReader.<init>(Unknown Source)
at History.getFile(History.java:14)
at History.main(History.java:19)
I don't know why it should run fine with the Java console, and why it should
not run fine in Eclipse. The History.d1 which is the input file is in the
output folder where the class file is. Can someone tell me what's going on? The
source code for the application is below.
import java.io.*;
import java.util.Scanner; // Import Scanner class
public class History
{
static Scanner inFile; // Declare Scanner object
static PrintWriter outFile; // Declare PrintWriter object
static String inputString; // Line of text from file
static final String blanks = " "; // String constant to indent paragraphs
static void getFile() throws IOException
{
// Instantiating new scanner and new filereader object
inFile = new Scanner(new FileReader("History.d1"));
}
public static void main(String[] args) throws IOException
{
getFile(); // Call method getFile()
// Instantiating new printWriter and FileWriter object
outFile = new PrintWriter(new FileWriter("history.d2"));
// Add blanks and first line
inputString = blanks+inFile.nextLine();
// Print indented line to file
outFile.println(inputString);
// Until there are no more lines to read
while (inFile.hasNextLine())
{
inputString = inFile.nextLine(); // Read in another line
if (inputString.length() < 1) // If line is empty
{
inputString = inFile.nextLine(); // Read in another line
if (inputString.length() < 1) // If line is empty
{
inputString = inFile.nextLine(); // Read in another line
outFile.println("\n"); // Print blank line to file
inputString = blanks+inputString; // Indent stored line with blanks
outFile.println(inputString); // Print indented line to file
}
else // Otherwise
{
outFile.println("\n"); // Print blank line to file
inputString = blanks+inputString; // Indent stored line with blanks
outFile.println(inputString); // Print indented line to file
}
}
else // Otherwise
{
outFile.println(inputString); // Print line to file
}
}
// Clos files
inFile.close();
outFile.close();
// Print statement tells the user the application is fimished.
System.out.println("Finished");
}
}
