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

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:
/* * To change this license header, choose License Headers in Project Properties. * To change this template file, choose Tools | Templates * and open the template in the editor. */
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 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?
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 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); } } }
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);
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");
[Code] .....
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:
So my EL expressions in my jsp are not taken into account in my project. It was working fine when I was using DAO but I switched my project to ORM using the annotations. Using Tomcat in the first place and now JBoss 7.2. Anyway take a look because I really don't understand what I have to do.
When I acces the page I create I get this : OyN3K.jpg while I'm supposed to have a form.
I don't think it's an error in my code but more or less a configuration problem. Btw I don't think it's a problem in my url since when I put a wrong one I've an error telling me it doesn't find the jsp file. That said it's clearly the ${} not being taken into account.
I understand how mixing expressions of different data types can result in an error if the assigned variable is not the same data type. But I don't understand how the below causes an error:
short totalPay, basePay = 500, bonus = 1000; totalPay = basePay + bonus; // This causes the error
500 + 1000 = 1500. 1500 falls within the short parameters. If basePay, bonus, and totalPay are all short, as well as the resulting equation, how is this erroring?
This is a program to input a sentence and print the words that start with a vowel.......There is no syntax error but on executing and typing the sentence and pressing enter,I get a error saying :
java.lang.StringIndexOutOfBoundsException: String index out of range: 0 at java.lang.String.charAt(String.java:658) at sentence.main(sentence.java:22)
I am trying to build an expression tree program . I try to print it then I have java.nullpointer exception . Is it error in my code or what ?
I have 2 classes
one is BSTreeNode which is the nodes for the tree . It has
public class ExpressionTree { public BSTreeNode root; public BSTreeNode curr = root; ExpressionTree() { root = new BSTreeNode(null, null, null, null); curr = root;
[Code] ....
My BSTreeNode
public class BSTreeNode { BSTreeNode parent; Object element; // Binary search tree element BSTreeNode left; // Reference to the left child BSTreeNode right; // Reference to the right child // Constructor BSTreeNode (Object elem) [Code] ....
The error i am getting is
Exception in thread "main" java.lang.NullPointerException at binaryexpressiontree.ExpressionTree.insert(ExpressionTree.java:38) at binaryexpressiontree.test.main(test.java:22)
Java Result: 1
After implementing exception handler what i am getting is
java.lang.NullPointerException root 1 * root 2 1 error error error//these error print because of my catch clause
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");
I have a enum class which contains some string which i am comparing to a string i get from a user
Java Code:
public enum Compare { a, b, c, d, e, f } class SomeClass { String method(String letter){ Compare word= Compare.valueOf(letter); } } mh_sh_highlight_all('java');
Everything works fine but when I added a new word to it like "g" it throws the IllegalArgumentException ?
I am attempting to create a very simple game where two squares move around and each can see the other square moving. This is a multi-player game over a TCP network using JavaFX. I am getting an illegal state exception when I call requestFocus(). This is my server:
public class GameServer extends Application { ObjectOutputStream p1out; ObjectOutputStream p2out; int PLAYER1 = 1; int PLAYER2 = 2;
