public void printBankNotePairs(Wallet other)

StringBuffer myBuffer = new StringBuffer("Pairs: ");
for(int i = 0; i < count; i++)

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
}^.

I am writing a short program to find the zodiac of a given birth date. I am checking to see if a calendar object falls between to other objects to see if the date falls within a certain zodiac sign. To accomplish this, I have the user enter a date, then that date is compared to dates taken from an array. The problem is sometimes the comparison doesnt seem to work work, giving the wrong zodiac. For example if I enter 03/28/1968, it finds Aries, as expected. However if I enter 03/20/1968, it returns Aries also, when it should return Pisces. Here is the sample code.
private static String determineSign(Date birthdate, String[][] zodiac) throws ParseException {
// TODO Auto-generated method stub
Date date = birthdate;
for (int row = 0; row < zodiac.length; row++)
{
DateFormat date3 = new SimpleDateFormat("MM/dd");
Calendar compDate3 = Calendar.getInstance();
[Code] .....
This is the class that creates the table used for the zodiac dates -
public class ZodiacTable {
static final int ROWS = 12;
static final int COLUMNS = 3;
//private ArrayList<String> zodiacNames;
private String[][] zodiacNames;
[Code] ....
I cant seem to see why it returns the wrong zodiac..

I am writing a program that calculates the prices of 4 items from a menu after the user inputs how many of each item. I need to print which item cost the most. Is there a simple way of coding this or do i need to code a bunch of if else statements. Here is what I have so far.

I was writing a code to have the library books classified in name, author, area, ed, etc. I'm using NetBeans and it doesn't accuse any error. But when I run the project, it never goes right and shows the books only in one area, regarthless what I type. (The goal of the algorithm is to separate the books in areas (sciences, humanities and biological science).

Ok, so the program we are supposed to do is to create implement a employee class then create a main tester class that can accept user inputs for 5 employee names, salaries, and performance rating. After that, we have to input code to calculate a provided raise amount, then print out the array with the updated raises. I have completed the program with no syntax errors, but it doesn't do anything. not even a screen comes up on my end to accept user inputs. I know its something basic, but what am i missing
Employee class
public class Employee
{
private String employeeName;
private int salary;
private int performanceRating;

I'm trying to have the program create a .txt file for me but it is not working properly. It just keeps printing the exception error "The file could not be found" and exits the program.
// This program asks the user for input for a name, phone number and notes up to 200 entries.
// It stores every contact in a file. Type 'h' for help while running this program.
import java.util.Scanner;
import java.io.*;
public class Phonebook {
static Entry[] entryList = new Entry[200];
static int numEntries;
public static void main(String[] args) {

After running the code, I go into my workspace folder and I see that the file was created. What to do because running the program will always print "could not find the file".

What are the x- and y-coordinates of the Points referred to as p1, p2, and p3 after the following code executes? Give your answer as an x-y pair such as (0, 0). Recall that Points and other objects use reference semantics.
PHP Code:
Point p1 = new Point();
p1.x = 17;
p1.y = 9;
Point p2 = new Point();
p2.x = 4;
p2.y = -1;
Point p3 = p2;
p1.translate(3, 1);
p2.x = 50;
p3.translate(-4, 5); mh_sh_highlight_all('php');
P1:
P2:
P3:
My guesses were: P1:(20,10) //Correct
P2:(50,-1) //Incorrect
P3:(0,4) //Incorrect

Create a class called DiceStatistics to represent a pair of dice and the totals of their rolls. It should have an array of two Dice as a private data member (these are the Dice from Problem 1). It should also have, as a data member, an array of integers to represent the possible totals of rolling two dice.
The class should also have the following methods:
initStats() to initialize all the totals to zero.
rollOnce() to roll each die once, and add one to the correct totals element
printStatistics() to print the number of times each total has come up over the number of runs.
Here is my code:
public class DiceStatistics {
private final int NUMBER_OF_DICE = 2;
private Dice[] dice = new Dice[NUMBER_OF_DICE];
private int[] totals;
private int numberOfRolls;
[Code] ....
And here is the error:
run:
Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - Erroneous sym type: Dice.roll
at DiceStatistics.rollOnce(DiceStatistics.java:27)
at DiceStatistics.main(DiceStatistics.java:55)
Java Result: 1
BUILD SUCCESSFUL (total time: 0 seconds)
I know it has something to do with the fact that I need to somehow import the information from my first program "Dice" into this in order to actually get the dice statistics, but how do I do that?

I have been having difficulty with the weeks concepts in my online Java class, the program is to be as followed:
For this exercise you will implement a class called Pair, that represents a pair of two numbers.The Pair class should include the following constructor and methods:
CONSTRUCTORS
public Pair(double num1, double num2) -- Creates an object that represents a pair of double values
METHODS
public double getAverage() -- Returns the average value of the two numbers
public double getDistance() -- Returns the absolute vale of the distance between the two numbers
public double getMaximum() -- Returns the maximum value of the two numbers
public double getMinimum() -- Returns the minimum vale of the two numbers
Write a class called PairTest that tests your Pair implementation. The PairTest should prompt the user for the two values, create a Pair object with the values and then print the average, distance, maximum, and minimum of the pair. The input / output should look like the following:
Enter the first number: 5.5
Enter the second number: 3.0
Average: 4.25
Distance: 2.5
Maximum: 5.5
Minimum: 3.0
NOTE: For this exercise, your solution should not use any conditional statements. Instead you should use the methods provided by thejava.util.Math.
So far I have:
import java.lang.Math;
import java.util.Scanner;
public class Main
{
public static void main(String args[]) {
Scanner in = new Scanner(System.in);
{
System.out.println("Please enter a value for the first number");
[Code] ....
