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; }

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?

double salary;
double commission;
double totalSales;
double annualComp;
double salesTarget;

double incentive1;

Lines 7 , 10 ,13 .... All have a Illegal Start of Expression error.

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);

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: ");

^void show

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.

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");

Write a method that accepts an array of Strings. The method must return an array containing all strings that start with the letter 'A'.
There must be no 'null' values in the resulting array. The resulting array may be of size zero.
I don't think I am returning ALL the strings that start with A, just the last one of the for loop. Does this look somewhat correct?
public String[] startsWithA(String[] strings) {
String startsWithA = strings[0];
for(int i = 0; i < strings.length; i++) {
if(strings[i].charAt(0) == 'A') {
startsWithA = strings[i];
}
return startsWithA;
}
}
I am writing a program for a game. It is between the user and a virtual player. The game starts with a pool of consecutive integers 1-100. The size of the pool is based on a random generated number at the beginning of the game. At the start, both players' scores are 0. For each turn, the player picks one number from the pool. That value is added to the player's score, the computer gets the sum of all the remaining numbers in the pool that divide evenly into the player's pick. The player's pick and its divisors are then removed from the pool.
The player should be able to play the game as many times as she wants without ending the program. Instructions should appear on the screen only once at the start of the program.
For each turn, both players' current score, the current pool of numbers, and a prompt for a number to be entered should show onscreen. I have written the code until I get to the function that updates the pool of numbers after a turn.
import java.util.Scanner;
import java.util.Random;
public class SlickPick {
public static void main (String[] args){
Scanner read = new Scanner(System.in);
int []pool = new int[100];
[Code] ....
My thinking is that I need to use the binary search to find the indexes of the divisors array and then use those indexes as the start values. I'm not sure how to assign the divisors indexes to start. Do I need an array for start? Whenever I run the program, the only value missing is 3.
//Name : poolUpdate
//Description : This function modifies the contents of the pool as a result of a turn of play.
//Parameters : The pool array, the divisors array, the size, and the user's pick.
// :
//Return :
public static void poolUpdate(int[] pool, int[] divisors, int size, int pick){
int low=0;
int high=size-1;

I accidentally wrote a code differently than what I should've, and I got these errors :
"Illegal modifier for parameter a; only final is permitted"
"Illegal modifier for parameter b; only final is permitted"
"Illegal modifier for parameter c; only final is permitted"
The code that I wrote and gave these errors:
Java Code:
class Math {
public static void main(String[] args) {
static int a = 11;
static int b = 35;
static int c = 29;
//the rest of the code below
[Code] ....
I noticed that I can declare "static int" only under "class Math" and not under "public static void main".(I had to remove "static" if declaring int under "public static void main");

Everything works fine but when I added a new word to it like "g" it throws the IllegalArgumentException ?
