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
}^.

CountSpaces Method - Illegal Start Of Expression?

Jul 21, 2014

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);

Count Number Of 7s (User Input) - Illegal Start Of Expression

Oct 15, 2014

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);

First Time Using Generics - Incomparable Type Errors

Aug 29, 2014

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)

Printing Errors If F Or C Isn't Entered For Temperature Type

Nov 14, 2014

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();

JSF :: Target Unreachable - Identifier Resolved To Null

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).
