I am getting the error "Line 54, illegal start of expression". Line 54 is where my "for" starts. It was running ok earlier, now I can't get this error to go away?
Lines 7 , 10 ,13 .... All have a Illegal Start of Expression error.
[color=blue]private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) { Random rd = new Random(); int random = 0; random=rd.nextInt(6)+1; switch(random){
why the complier is giving the following error message "illegal start of expression" once it reach the countSpaces method.The way I see it (and I am obviously seeing it wrong), the code is public since why not, int since it returns an int # and the method has return int in it, and static I am not too sure but I get the same error message whether or not it is included
public static void main (String args[]) { Scanner in = new Scanner(System.in); String sentence; System.out.println("type a sentence"); sentence = in.nextLine(); countSpaces (sentence);
Why does this not work? I get an ']' expected at the y in the fourth line of code and an illegal start of an expression at the actual ] in the same line
int y = 0; JTextField response[] = new JTextField[10]; while(y < 10) { JTextField response[y] = new JTextField(7); add(response[y]); response[y].addItemListener(this); ++y; }
Here is my program and results and I am having a error on line 38 which is "public static long fib01(long paramLong)" The program does give me my results but I am trying to correct there error.
public static void main(String[] args) { { System.out.print("
" + String.format("%-10s", new Object[] { "Index" })); System.out.print(String.format("%-15s", new Object[] { "Fibonacci01" })); System.out.print(String.format("%-15s", new Object[] { "Fibonacci02" })); System.out.println(String.format("%-15s", new Object[] { "Fibonacci01" }));
I'm working on a program and can't seem to fix my for loop error.I get an error at the for loop line saying illegal start of expression and i don't know how to fix it:

I need to know why this program is giving me error (illegal start of expression). What must i do to stop the error?
//Read a character from keyboard class Kbin{ public static void main(String[]args){ throws java.io.IOException{ char ch;
System.out.print( " Press a key followed by ENTER: "); ch = (char) System.in.read();//read character from keyboard System.out.println( "Your key is: " + ch); } } }
public static void main(String[] args) { Scanner Keyboard = new Scanner(System.in); System.out.print("Please enter your name."); String name = Keyboard.next(); name = "name";
I'm attempting to create a program that employs a method to count the number of 7s a user puts as an input into the program. I'm just getting started, but I'm getting an error when I try to implement a main method that says "Illegal start of expression"
What adjustments could I make to eliminate this error message?
// Add a main method here. public static void main(String[] args) { //Error occurs here public static int countSevens(int n) { // 0. Clean-up. Get rid of any minus signs as that is not a digit. n = Math.abs(n);
This specific assignment requires me to write a program that calculates the total sales after each football game. There are 4 types of tickets: box, sideline, premium, and general admission. After each game, data is stored in a file... then output the number of tickets sold and total sale amount. Format your output with 2 decimal places.
Okay I know there is a I/O section and wasnt sure where to post this. I need some insight on how to use file input and output as well ... Here is my program:
import javax.swing.JOptionPane; import java.text.DecimalFormat; public class ticketsSold { public static void main(String[] args) { String BoxSeat; String SideLine;
I'm working through Head First Java, and I'm struggling with the chapter 6 magnet exercise on page 161. I've checked my answer countless times, and it appears to match the book's code, but when I try to run it on my computer I'm getting an error. It says:
error: <identifier> expected System.out.println^(" "); and
error: illegal start of type System.out.println(^" ");, both for line 32.
I cannot seem to figure out what is different about my code!!
import java.util.*;
public class ArrayListMagnet { public static void main (String [] args) { ArrayList<String> a = new ArrayList<String>(); a.add (0, "zero"); a.add(1, "one"); a.add(2, "two"); a.add(3, "three");

Also, I'm not sure if this has anything to do with the above errors, but I'm getting a third error message for line 34 saying:

Design a program that will read a file of sales records and produce a sales report. Each record in the file contains a customer's ID, name, a sales amount, and a validated GST code. The GST code is to be applied to the sales amount to determine the sales tax due for that sale, as shown below.
GST CodeGST Rate 0 1 20% 5% 10%
The report is to print a heading "SALES REPORT", and detail lines listing the customer's ID, name, sales amount, sales tax, and total amount due including sales tax.

How would I get my program to display a * for every 100 dollars in sales that the user enters in so: for example the user enters in store 1: $ 400 in sales for the store I want it to display store 1:****
The first part of my code allows the user to enter in whatever values the stores have in sales. The Second half of the code starts at line 19 is my best guess on what I need to do I just am not sure how to get it to display what I need it to.
my project is to design a class that stores the number of units sold and has a method that returns the total cost of the purchase..the given info is unit are $99. discounts are 20% for 10-19 units; 30% for 20-49 units; 40% for 50-99 units; and 50% for 100 or more units purchased... When i run the code and put in the units sold it returns: 0 units sold, $0.00 cost, 0% discount. How do I get the output to actually do the equation and give proper information. We were given a demo file from the instructor and had to create a class that works with it first set of code is the demo file:
package chapter4; import java.text.DecimalFormat; import java.util.Scanner; /** * SoftwareSalesDemo Program */ public class SoftwareSalesDemo { public static void main(String[] args) { int units; // To hold units sold
The manager of a football stadium wants you to write a program that calculates the total ticket sales after each game. There are four types of tickets: box, sideline, premium, and general admission. After each game, the data is stored in a file in the following format:
ticketPrice numberOfTicketsSold
Sample data might look like:
250 5750
100 28000
50 35750
25 18750
The first line indicates that the box ticket price is $250 and that 5750 tickets were sold at that price.
Your program should input in this data (using Scanner or an input dialog box), then output that data to a message dialog box along with total ticket sales information. Output the total number of tickets sold and the total sale amount. Make your output user-friendly and "pretty". Format your output with two decimal places. Use JOptionPane and the formatting techniques learned in chapter 3 for your output. Example output might be:
5750 Box Tickets sold at $250.00 28000 Sideline Tickets sold at $100.00 35750 Premium Tickets sold at $50.00 18750 General Admission tickets sold at $25.00
The area of a square is stored in a double variable named area . Write an expression whose value is length of the diagonal of the square. Do I use math.sqrt?
