Why this program cannot run in Java Eclipse:

ReadFile.java

package readfile;

import java.io.File;
import java.io.FileNotFoundException;
import java.io.PrintWriter;
import java.util.Scanner;

public class ReadFile {

@SuppressWarnings({ "resource", "unused" })

Scanner S = new Scanner(System.in);
System.out.print("Enter input file name:");
String fileName = S.nextLine();
try {
Scanner fileInput = new Scanner(new File("JaneScheduleData.txt"));
System.out.print("Enter output file name:");
fileName = S.nextLine();
PrintWriter outputFile = new PrintWriter(new File("JaneScheduleReport.txt"));
String firstName = fileInput.nextLine();
String lastName = fileInput.nextLine();
// The program should always work for a properly formatted input
// file. You should use a
// loop to read in the data. Each time through the loop you should
// process one record from
// the file (read it in, do any necessary calculations, and write it
// out). I may test your
// program with an input file that contains a different number of
// records then the file you
// used as input to your program (for example 20 instead of 12). If
// the program does not
// work on my input file then it will be marked as incorrect.
outputFile.println(" Schedule Report");
outputFile.println(" ---------------");
outputFile.println();
outputFile.println("First: "+firstName);
outputFile.println("Last: "+lastName);
outputFile.println(" M D Y Hr Mn Pd Category Description");
outputFile.println(" - - - -- -- -- -------- ----------- "); 
int pmCount=0;

Explanation / Answer

You only need to run the ReadFile.java file. There is no need for the JaneFile.java

import java.io.File;
import java.io.FileNotFoundException;
import java.io.PrintWriter;
import java.util.Scanner;
public class ReadFile {
   @SuppressWarnings({ "resource", "unused" })
   public static void main(String[] args) {
       // TODO Auto-generated method stub
       Scanner S = new Scanner(System.in);
       System.out.print("Enter input file name:");
       String fileName = S.nextLine();
       try {
           Scanner fileInput = new Scanner(new File(fileName));
           System.out.print("Enter output file name:");
           fileName = S.nextLine();
           PrintWriter outputFile = new PrintWriter(new File(fileName));
           String firstName = fileInput.nextLine();
           String lastName = fileInput.nextLine();
           // The program should always work for a properly formatted input
           // file. You should use a
           // loop to read in the data. Each time through the loop you should
           // process one record from
           // the file (read it in, do any necessary calculations, and write it
           // out). I may test your
           // program with an input file that contains a different number of
           // records then the file you
           // used as input to your program (for example 20 instead of 12). If
           // the program does not
           // work on my input file then it will be marked as incorrect.
           outputFile.println(" Schedule Report");
           outputFile.println(" ---------------");
           outputFile.println();
           outputFile.println("First: "+firstName);
           outputFile.println("Last: "+lastName);
           outputFile.println(" M D Y Hr Mn Pd Category Description");
           outputFile.println(" - - - -- -- -- -------- ----------- ");
           int pmCount=0;
           int amCount=0;
           while (fileInput.hasNextInt()) //

               fileInput.nextLine();
               String period= fileInput.nextLine();
               if(period.equals("PM"))
               {
                   pmCount++;
               }
               if(period.equals("AM"))
               {
                   amCount++;
               }
               String Category = fileInput.nextLine();
               String Description = fileInput.nextLine();;
               outputFile.printf("%02d %02d %4d %02d %02d %2s %-12s %-12s",
                       Month,Day,Year ,Hour,minute,period,Category,Description );
               outputFile.println();
           }
           outputFile.println();
           outputFile.println("Summary");
           outputFile.println("-------");
           outputFile.println("AM appointments: "+amCount);
           outputFile.println("PM appointments: "+pmCount);
           outputFile.close();
       } catch (FileNotFoundException e) {
           e.printStackTrace();
       }
   }
   public void openFile() {
       // TODO Auto-generated method stub
   }
   public void readFile() {
       // TODO Auto-generated method stub
   }
   public void closeFile() {
       // TODO Auto-generated method stub
   }
}
