Identifier Expected And Illegal Start Of Type Errors
Aug 6, 2014
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:
error: class, interface, or enum expected
}^.

When do you get the error <identifier> expected? I've written a small application where input is accepted by a textfield and based on some condition a dialog should be displayed saying "invalid i/p". But am not able to correct ths particular error ....

I created a superclass Ships and under that a class CivilShips. Under that HumanBulkFreighter.
I declared variables in Ships and CivilShips and wanted to have them set in HBF to a specific value. When I know try to compile them I get the following:

Where are all these illegal start of operations and all of these other method errors coming from.I've written enough methods not to have this problem.
----jGRASP exec: javac -g Assessement.java
Assessement.java:29: error: illegal start of expression

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; }

I keep getting this error upon compiling and can't see the problem with it.
The error is on line "45: 15"

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 am trying to make a generic method that will replace the data type T with those number types usable with a Scanner object. However, whenever I try to compile, I get errors saying that a Byte/Integer/Double etc are found when only a type T is allowed. This is the beginning of my method. I can;t understand what is wrong with it.
Java Code:
public <T extends Number> T nextRanged(T lowerBound, T upperBound, boolean inclusive, String errorMessage){
// Holds program execution until user inputs a numeric value between the bounds. Prevents all other input without exception.
// Output data type determined by the type of the bounds.
T input = null;
try{
if(input instanceof Byte){
input = new Byte(internalScanner.nextByte());
[Code] ....
The purpose of the method, in the end, will be to provide the nextXXX() functionality of a Scanner object but with built in validation procedures. I could easily do this by making a nextIntRanged(), nextDoubleRanged() etc methods, but this seems wasteful to me.
I meant "incompatible type errors"!
Error example:
ValidatedScanner.java:57: error: incompatible types
input = new Byte(internalScanner.nextByte());
^
required: T
found: Byte
where T is a type-variable:
T extends Number declared in method <T>nextRanged(T,T,boolean,String)

I am trying to get it to print out an error if F or C isn't entered for the temperature type, but the code I am taking from one of my other similar programs isn't working for some reason.
Also, when I type a string in the temperature I get an exception....I can do the same with that as I would the temp type? I think I may just be putting the code in the wrong spot and thats why it isn't working..
public static void main(String[] args)
{
Scanner input = new Scanner(System.in);
System.out.print("Please enter F for Fahrenheit or C for Celsius: ");
String fOrC = input.next();

I am following this article [URL] .... till now I have made some code
This is my Interface
public interface Comparable<T> {
public int compareTo(T o);
}
And this is my class where I am using Bound Type Parameter on Generic Methods
public class GenericMethodBoundType {
public static <T extends Comparable<T>> int countGreaterThan(T[] anArray, T elem) {
int count = 0;
for (T e : anArray)
[Code] .....
What else I need to do both in main method and at what parameterized types I need to pass at the class?

I've created a constructor in bean and put an value to my string after doing so all started to work properly. I am trying to get my application to work but no luck so far. I have looked for similar issues but although there were similar I've got no luck in fixing mine.
When I am trying to put an value in the input file i got error message (/zadanie_1.xhtml @15,75 value="#{z_1.lancuch}": Target Unreachable, identifier 'z_1' resolved to null).
