thanks for the help.

Hi I am having problems with a program in that I am supposed to be sorting some objects with a general objects sort that I was given, and I am now recieving this compile error:
E:\Spring Bench\Bench\Chapter 6 part 2\6.12\Tunes.java:30: cannot resolve symbol symbol : method insertionSort (CDCollection) location: class Sorts Sorts.insertionSort(music); ^ 1 error Tool completed with exit code 1
Here is the Program that I having proplems with.
public class Tunes { //----------------------------------------------------------------- // Creates a CDCollection object and adds some CDs to it. Prints // reports on the status of the collection. //----------------------------------------------------------------- public static void main (String[] args) { CDCollection music = new CDCollection (); music.addCD ("Storm Front", "Billy Joel", 14.95, 10); music.addCD ("Come On Over", "Shania Twain", 14.95, 16); music.addCD ("Soundtrack", "Les Miserables", 17.95, 33); music.addCD ("Graceland", "Paul Simon", 13.90, 11); System.out.println (music); music.addCD ("Double Live", "Garth Brooks", 19.99, 26); music.addCD ("Greatest Hits", "Jimmy Buffet", 15.95, 13); Sorts.insertionSort(music);//LINE INPUTED WITH PROBLEM System.out.println (music); } }
Here is the Sorts program I am working with.
public class Sorts { //----------------------------------------------------------------- // Sorts the specified array of integers using the selection // sort algorithm. //----------------------------------------------------------------- public static void selectionSort (int[] numbers) { int min, temp; for (int index = 0; index < numbers.length-1; index++) { min = index; for (int scan = index+1; scan < numbers.length; scan++) if (numbers[scan] < numbers[min]) min = scan; // Swap the values temp = numbers[min]; numbers[min] = numbers[index]; numbers[index] = temp; } } //----------------------------------------------------------------- // Sorts the specified array of integers using the insertion // sort algorithm. //----------------------------------------------------------------- public static void insertionSort (int[] numbers) { for (int index = 1; index < numbers.length; index++) { int key = numbers[index]; int position = index; // shift larger values to the right while (position > 0 && numbers[position-1] > key) { numbers[position] = numbers[position-1]; position--; } numbers[position] = key; } } //----------------------------------------------------------------- // Sorts the specified array of objects using the insertion // sort algorithm. //----------------------------------------------------------------- public static void insertionSort (Comparable[] objects) { for (int index = 1; index < objects.length; index++) { Comparable key = objects[index]; int position = index; // shift larger values to the right while (position > 0 && objects[position-1].compareTo(key) > 0) { objects[position] = objects[position-1]; position--; } objects[position] = key; } } }
Here is the program that I pulled that line of code from to create an insertion sort...

public class SortPhoneList { //----------------------------------------------------------------- // Creates an array of Contact objects, sorts them, then prints // them. //----------------------------------------------------------------- public static void main (String[] args) { Contact[] friends = new Contact[7]; friends[0] = new Contact ("John", "Smith", "610-555-7384"); friends[1] = new Contact ("Sarah", "Barnes", "215-555-3827"); friends[2] = new Contact ("Mark", "Riley", "733-555-2969"); friends[3] = new Contact ("Laura", "Getz", "663-555-3984"); friends[4] = new Contact ("Larry", "Smith", "464-555-3489"); friends[5] = new Contact ("Frank", "Phelps", "322-555-2284"); friends[6] = new Contact ("Marsha", "Grant", "243-555-2837"); Sorts.insertionSort(friends); for (int index = 0; index < friends.length; index++) System.out.println (friends[index]); } }

I just added that last bit for people to look at so they could compare it. I figured too much info is better than too little. Thanks in advance for your help on the matter.

I was having problems with incompatible types on a string to be read. I want to read a string and each letter be printed on a seperate line...right now I am working on this line....
for (i = 0; i < sentence.length();++ i) { place = Character.toLowerCase(sentence.charAt(i));
here is the error when compiling.

A:\Chapter 3\Bench\StringRead.java:22: incompatible types
found : char
required: java.lang.String
place = Character.toLowerCase(sentence.charAt(i));
^
1 error
Tool completed with exit code 1

I understand the basics of objects, but I am still working on how to use the api right. Could anyone point me out to a tutorial that would help me? Thank you very much. Here is the entirety of the program still in progress....

import cs1.Keyboard;
public class StringRead
{

public static void main (String[] args)
{
String num, place, sentence;
int i , letter;
System.out.println ("Please put in a string of letters or a sentence...");
sentence = Keyboard.readString();
for (i = 0; i < sentence.length();++ i)
{
place = Character.toLowerCase(sentence.charAt(i));
}
}
}

Thanks again for your help and time....

Hi again...
Sorry to bug you guys about the same old program but I am having having problems getting to the methods of Guest.java to do graphic commands. It all comppiled fine but when Diner.java implements
"placeCheck();" & "colorCheck(page);" it does'nt show up in the applet when I run it.
Here is:
Guest.java
Diner.java

THANK YOU SOOOOO MUCH FOR YOUR HELP!!!

import java.applet.Applet; import java.awt.*; public class Guest extends Object { private int place; private int gender ; private String owner; private int placeX; private int placeY; private int width = 50; private int x = 54, y = 73; private int tableWidth = 79, tableHeight = 140; //----------------------------------------------------------------- // Sets up the account by defining its owner, account number, // and initial balance. //----------------------------------------------------------------- public Guest (String owner, int gender, double place) { } public int colorCheck (Graphics page)//draws circle according to sex { switch (gender) { case 1: //male { page.setColor (Color.blue); page.fillOval (placeX, placeY, width, width); page.setColor (Color.black); page.drawString (owner, placeX, placeY); break; } case 2://female { page.setColor (Color.pink); page.fillOval (placeX, placeY, width, width); page.setColor (Color.black); page.drawString ( owner, placeX, placeY); break; } } return gender; } public int placeCheck ()//draws spot according to variable "place." { switch (place) { case 1: //place 1 { placeX = 39; placeY = 90; break; } case 2://place 2 { placeX = 39; placeY = 140; break; } case 3: //place 3 { placeX = 148; placeY = 90; break; } case 4: //place 4 { placeX = 148; placeY = 140; break; } } return gender; } }
import java.applet.Applet; import java.awt.*; import Guest; public class Diner extends Applet { //----------------------------------------------------------------- // Creates guests at party!!! //----------------------------------------------------------------- public void paint (Graphics page) { Guest webly= new Guest ("Webly", 2, 1); Guest brian = new Guest ("Brian", 1, 2); Guest mom = new Guest ("Mom", 2, 3); //----------------------------------------------------------------- // Makes a Table //----------------------------------------------------------------- page.setColor (Color.black); page.drawRect ( 54, 73, 79,140 ); //----------------------------------------------------------------- // Calls methods for showing guests //----------------------------------------------------------------- webly.placeCheck(); webly.colorCheck(page); brian.placeCheck(); brian.colorCheck(page); mom.placeCheck(); mom.colorCheck(page);

I JUST WANTED TO LET YOU GUYS KNOW THAT THIS SITE MAKES ME LEARN THREE TIMES AS FAST, THANK YOU FOR YOUR INPUT.

Thank you that helped very much.....

Hello again,
I was wondering if I could get help with the ColorCheck method I built I think I am having problems with me putting the "Graphics page" between it's parathesis. If I did'nt when I would compile it would'nt recognize page.setColor in Guest.java. But when I would compile my second program it says I can't apply the Graphics page to Colorcheck (). So I don't know what to do....
-Here is the following in this order:
Code for Guest.java (program to set up methods)
Code for Diner.java (program to envoke methods)
Compile error for Diner.java

THANK YOU VERY MUCH FOR YOUR TIME AND HELP

I'm having a problem with this program below it seems to not resovle the "page.fillOval", here is the program. Mind you this is still a work in progress, thank you for your help....

Here is the compile errors:

thanks again for your help...

Thanks for the help you guys I figured out the problem and I decided to use the switch statement instead, I will definatly use that in the future. THANK AGAIN!!!

I am writing a program that will read a string of letter and then be able to spit out the number of each vowel of that string.Here is the code I have been writing. I am unable to figure out why for the variable place I am unable to make it a variable string, rather than a integer that will compile fine.
import cs1.Keyboard; public class SayLetter { public static void main (String[] args) { String Letters; String a = new String("a"); String e = new String("e"); String i = new String("i"); String o = new String("o"); String u = new String("u"); int spot , numberA = 0, numberE = 0, numberI = 0, numberO = 0, numberU = 0;// to hold how many of each letter int AllLetters; String place; System.out.println ("Put in String of Letters");//sets up input Letters = Keyboard.readString(); for (spot = 0; spot < Letters.length();++ spot)//loop for place in line { place = Character.toLowerCase(Letters.charAt(spot));//says where to look in string String NewLetter = new String (place);//to hold letter to be compared against if (NewLetter == a)// these if else statments tally the number of each letter that has been provided ++ numberA; else if (NewLetter == e) { ++ numberE; } else if (NewLetter == i) { ++ numberI; } else if (NewLetter == o) { ++ numberO; } else { ++ numberU; } } AllLetters = numberA + numberE + numberI + numberO + numberU; System.out.println ("A: "+numberA); System.out.println ("E: "+numberE); System.out.println ("I: "+numberI); System.out.println ("O: "+numberO); System.out.println ("U: "+numberU); System.out.println ("The Whole String is:" +AllLetters); } }
I get the compile error

I wanted to thank you in advance for helpong me because tihs eludes me as to I am very much a beginner. THANK YOU FOR YOUR TIME

thanks for the help....

IS there a Java eqiuvalent for a Goto statement?
like
if (Dots == 8)
Goto 10

THANK YOU..it helped alot.

I was having a problem with my code, this probably would'nt take long for somebody with more experience...thanks for the help.
import cs1.Keyboard; public class JarOCoins { public static void main (String[] args) { float Quarters, Dimes, Nickles, Pennies, HalfDough, TotDough; System.out.println ("How many Quarters in the Jar?"); Quarters = Keyboard.readInt(); System.out.println ("How many Dimes in the Jar?"); Dimes = Keyboard.readInt(); System.out.println ("How many Nickles in the Jar?"); Nickles = Keyboard.readInt(); System.out.println ("How many Pennies in the Jar?"); Pennies = Keyboard.readInt(); Quarters = (Quarters * .25); Dimes = (Dimes * .10); Nickles = (Nickles * .05); Pennies = (Pennies * .01); TotDough = Quarters + Dimes + Nickles + Pennies; System.out.println ("You have $"+ TotDough +" in the jar."); } }
here would be the errors to make it easier

THANK YOU...IT DID

here is the code to make it easier to look at then the original post.
