Why "illegal start of expression" error? Please help!
Hello great java minds. Could you please tell me why I get "illegal start of expression" errors for the following headers? Thanks for your wisdom!!
Lines generating this error:
publicstatic String getName()
--and--
publicstaticvoid displayResults()
Here is my first class (that includes this code):
import java.io.*;
import java.util.*;
publicclass ProductSurvey
{
publicstaticvoid main(String [] args)
{
ProductData myData =new ProdcutData();
String name = getName();
openFile();
myData.setName(name);
myData.dataRetrieve(name);
myData.updateAverages(rating1totalLow, rating2totalLow, rating3totalLow, rating1totalMed, rating2totalMed, rating3totalMed, rating1totalHigh, rating2totalHigh, rating3totalHigh, inc1total, inc2total, inc3total);
mydata.setRating2ave1lower3(rating2lower1than3, lower1than3Total);
displayResults();
publicstatic String getName()
{
System.out.println("Please enter income and product info file name: ");
Scanner keyboard =new Scanner(System.in);
String name = keyboard.next();
return name;
}
publicstaticvoid openFile();
{
File fileObject =new File(name);
while ((! fileObject.exists()) || ( ! fileObject.canRead()))
{
if( ! fileObject.exists())
{
System.out.println("No such file");
}
else
{
System.out.println("That file is not readable.");
}
System.out.println("Enter file name again:");
name = keyboard.next();
fileObject =new File(name);
}
}
publicstaticvoid displayResults()
{
System.out.println("\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n");
System.out.println("*Average (rounded) product ratings, by income bracket, are as follows: ");
System.out.println(myData.toString());
System.out.print("\n*Total number of persons in Income Bracket $50000-$74999 ");
System.out.print("that rated all three products with a score of 5 ");
System.out.println("or higher: " + myData.getHighRaters());
System.out.print("\n*Average (rounded) rating for Product 2 by ");
System.out.println("persons who rated Product 1 lower than Product 3: " + myData.rating2ave1lower3);
}
}
}
