Illegal start of expression error
Hi, I keep getting an illegal start of expression error at the first parentheses of the main method, and I can't find the reason why. Any hints?
import java.util.*;
import java.io.*;
import java.text.*;
public class driver
public static void main(String[] args)
private String numerator, denominator;
private Scanner inScan = new Scanner(System.in);
System.out.print("Enter a numerator: ");
numerator = inScan.nextLine(); //get numerator
System.out.print("Enter a denominator: ");
denominator = inScan.nextLine(); //get denominator
EgyptianFraction fraction = new EgyptianFraction(numerator,denominator);
}String numerator, numerator;
Scanner inScan = new Scanner(System.in);Variables numerator, numerator and inScan are local variable, so there is no private modifer.
Suggestion: name your class Driver. There is a widely held coding convention that classes should start with a capital letter. -
How am i getting an illegal start of expression error?
Hi,
i am new to this forumn, and still fairly new to java i gues. i get an illegal start of expression in the following code at the line...
data [arrayCounter] = {fn,ln,hp,ha,hc,hs,hz};
any ideas as to why?
public class customersDatabase {
String[] columnNames = new String[10];
private Object[][] theData = new Object[1000][10];
public customersDatabase() {
String[] employeeNameArray = new String[10];
String retrieveString = "SELECT * FROM customerTable";
Statement stmt;
try {
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
} catch(java.lang.ClassNotFoundException e) {
System.err.print("ClassNotFoundException: ");
System.err.println(e.getMessage());
try {
con = DriverManager.getConnection(url, null, null);
stmt = con.createStatement();
ResultSet rs = stmt.executeQuery(retrieveString);
int arrayCounter = 0;
while (rs.next()) {
String fn = rs.getString("FIRSTNAME");
String ln = rs.getString("LASTNAME");
String hp = rs.getString("HOMEPHONE");
String ha = rs.getString("HOMEADDRESS");
String hc = rs.getString("HOMECITY");
String hs = rs.getString("HOMESTATE");
String hz = rs.getString("HOMEZIP");
data [arrayCounter] = {fn,ln,hp,ha,hc,hs,hz};
System.out.println(fn+ln+hp+ha+hc+hs+hz);
arrayCounter ++;
stmt.close();
con.close();
} catch(SQLException ex) {
System.err.println("SQLException: " + ex.getMessage());
}Change it to:
data [arrayCounter] = new String[] {fn,ln,hp,ha,hc,hs,hz};(or new Object[], but I don't know why your array is declared as Object[][], anyway, if you only put Strings in it.
You can only use the initialization you used when first declaring the variable.
Also, "data" should be "theData", I think. -

Error Prone Code. Need Help.
Last attempt to fix this code. I have included everything but the console code, which isn't needed here.
THIS IS ALL THE CODE IS SUPPOSED TO DO: Using a console, an Employee enters their name, then enters the numbers of hours they worked, then enters their hourly pay rate. Java then figures up the pay and then prints it out like this: (John Doe, 8.00, 40, 320 are just examples to show what completion would be like).
Your Name is: John Doe
Hourly Pay Rate: 8.00
Hours Worked: 40
Total Pay: 320.00
package Employee;
* <p>Title: Employee</p>
* <p>Description: Application allows an employee to enter a name, wage rate, hours worked and compute total pay.</p>
* @version 1.0
public class Employee() {
// field variables
private String name;
private double hours;
private double payRate;
private double Total;
public Employee() // empty constructor
// full constructor. 'Sets' do not return anything, thus void.
public Employee (String n, double h, double p, double t)
name = n;
hours = h;
payRate = p;
Total = t;
} // end full constructor
// 'Sets' do not return anything, thus void.
public void setName (String n)
name = n;
public void setHours (double h)
hours = h;
public void setpayRate (double p)
payRate = p;
public void setTotal(double t)
Total = t;
// get all of the field variables
public String getName()
return name;
public double getHours()
return hours;
public double getpayRate()
return payRate;
// public method to calculate pay
public double getTotal()
return Total;
public double Hours()
return hours;
public double payRate()
return payRate;
if (payRate >0)
return
Total = hours * payRate;
else

myEmployee.setpayRate(payRate);
double Hours = Console.readDouble ("Hours Worked");
myEmployee.setHours(Hours);
totalPayThisWeek = payRate * Hours;
// Output the results.
System.out.println("Your name is: " + myEmployee.getName());
System.out.println ("Hourly Pay Rate: " + myEmployee.payRate());
System.out.println ("Hours Worked: " + myEmployee.getHours());
System.out.println (" "); // Print a blank line
System.out.println("Total Pay: " + myEmployee.totalPayThisWeek());
System.out.println (" "); // Print a blank line
System.out.println("Please hit Enter to continue");
}HI: I found the problems in the Employee.java class. In the EmployeeDriver.java class, the errors are:
1. Malformed expression at line 15.
2. Illegal start of expression at line 18.
When I click on the error messages the lines public static void main ((String argv[])
{ highlight for the "malformed expression" error, and "illegal start" for the public Console = new Console(); line. I tried public Console, private Console, Employee Console and just plain Console, the same error message remained.
Here's the entire EmployeeDriver code: package Employee;

i have apple ipad air 32gb ,ios 7.0.3 , by mistake i have started the process of update on ios 8 , how can i stop this ? plz tell me.
The replies don't address the question: "I started getting bombarded with requests to upgrade to Firefox 5.0. This goes on all day, all night...it never stops. Is there a place I can ask you guys to please stop?"
I have the same problem: I also don't want to upgrade to 5.0 (4.0 messed me up enough and I finally got that straightened out). How do I stop those annoying requests? It should have a "No" option.
Please email replies to [email protected] Thanks. -
Invalid start of expression error
This is my first post, so I hope this is the right section.
I am trying to do an if statement to check for a flush in my poker game and I am getting an "Illegal start of expression " error.
Here is the loop:
for (int i = 0; i < numPlayers; i++)
if ((bestHands[0].getSuit() == bestHands[i][1].getSuit())&&(bestHands[i][0].getSuit() == bestHands[i][2].getSuit()) && (bestHands[i][0].getSuit()) == bestHands[i][3].getSuit()) && (bestHands[i][0].getSuit() == bestHands[i][4].getSuit())
flush = true;
Any help would be appreciatedYea, I did.
Here is the fixed code:
for (int i = 0; i < numPlayers; i++)
if ((bestHands[0].getSuit() == bestHands[i][1].getSuit())&&(bestHands[i][0].getSuit() == bestHands[i][2].getSuit()) && (bestHands[i][0].getSuit() == bestHands[i][3].getSuit()) && (bestHands[i][0].getSuit() == bestHands[i][4].getSuit()))
flush = true; -

i was updating my iphone 3g through itunes 11 then then suddenly an error occurs no.(1015) plz tell me guys how to solve this?
Here is what Apple has to say.
"Error 1015: This error is typically caused by attempts to downgrade the iPhone, iPad, or iPod touch's software. This can occur when you attempt to restore using an older .ipsw file. Downgrading to a previous version is not supported. To resolve this issue, attempt to restore with the latest iPhone, iPad, or iPod touch software available from Apple. This error can also occur when an unauthorized modification of the iOS has occurred and you are now trying to restore to an authorized, default state." -
i have an iPhone 5s 16gb. latest update is 8.0 ... i tried to download iOS 8.0.2 from boh way , iTunes and my phone but it keep shows me there is an error and i couldn't download new version .. so would u plz tell me what to do to sort this problem out.
thank youHi stripers
You will either a) need to connect to WiFi and complete the download or b) dock your iPad and remove it from the apps list once synced (your iTunes will more then likely want to complete the download first also, which you may be able to cancel in the downloads section).
