First you need to define what kind of structure to use in order to represent your tree. An array for example. Then you write code that inserts and reads the data, at and from the right place

It is : [ICODE]main(String [] args)[/ICODE] Also I think that you have the formula for surface_area wrong

What is the point of double threading? Wasn't one thread enough for you?

Apparently you are tying to use methods that don't exist. You don't just call methods just because you like it. You need yo declare them first

[QUOTE=chandanapiit;816131]hi any one online[/QUOTE] Hi, anybody home [I]chandanapiit[/I]?

You initialize the array, but you don't put values in it. So by default the values that it has are zero because the int variables are initialized to zero. This might not seem serious but if the array was String it would null. So next time, you don't just create …

Well assuming that this is not homework, I think that it is a good idea. I know that most of us, including stephen84s, can do this in 30 seconds, but others might learn from it and newbies may test their skill. Of course the OP could also add the link …

You wrote the code. Does it compile? If it does, is it so difficult to run it?

What kind of error, and didn't you notice the methods: subString, indexOf, or charAt. at the String API?

Also you don't need this in your class: [CODE] private Circle circles; [/CODE] In your class you define the ArrayList of circles, so you don't need that circle object. Everything will be put in that list and you will have methods that add and read or print from that list …

The method compareGuess should be inside a for-loop not a for-loop inside the method. The way you have you iterate, but the value "userRandom" doesn't change, so the same if is executed all the time. You need to have the method inside the loop and ask the user each time …

The line read is in the [ICODE]strLine[/ICODE] variable. Since you have already defined your array, you can simply put that value inside the array. Of course within each while-loop run you will need to increase the index of the array so you will put the next line to the next …

You were told to use get, set methods in your class and you used only a set method that changes all the variables of your class. In class: policeOfficer for example you have only a set method which is not what was suggested. Plus the attributes are declared private meaning …

Post your driver code and what errors you get

First of all in java is very simple. Classes to use: Date, SimpleDateFormat, Thread. And no we will not write the code. As instructed to other forum you posted ([URL="http://www.daniweb.com/forums/thread176644.html"]http://www.daniweb.com/forums/thread176644.html[/URL]), first try it yourself and we will see what we can do. Also if you want this done on a …

Not to mention that you failed to explain what is your problem. You just posted some piece of code without saying anything. Also you were the one that hijacked a 11 month old thread, whithout explaining anything and confusing everybody

[QUOTE=aodpreacher;804472]i know that you cant use Arrays.sort since it will only compare the one City array object[/QUOTE] What do you mean by that?

[QUOTE=youngstorm;796265]if the number was found in the array, I want to return that number[/QUOTE] Yes but what are you using to search the array? If you are using the number and want to see if it is there then you already have the number. If your method takes as argument …

Well the error is very simple. You should have figured it out form the compile message. Understanding compile messages is very important if you want to learn programming. [CODE] import java.io.DataInputStream; import java.io.FileInputStream; import java.io.IOException; [/CODE] You import those classes. You must also import the StringTokenizer [CODE] import java.util.StringTokenizer [/CODE] …

[CODE] CE emp1 = new CE("Martin", "Sheen", "420", 0.2, 100000); public CE(String fName, String lName, String secu, float commRate, float grossSales) [/CODE] When you write: [U]0.2[/U] java interprets it as a double. But your constructor accepts a float. So you need to "tell" java to treat [U]0.2[/U] as a float …

3 suggestions: Try printing the query and then run it at your database to see if it actually updates. Maybe the WHERE clause is false Maybe I am wrong, but try first to close the statement and the connection [U]and[/U] redirect And finally: THIS IS THE MOST IMPORTANT: Delete everything …

I think that because you do something like this: [CODE] String musicCd[] = { "Fergie", "Celine Dion","Kelly Clarkson", "Chris Daughtry"}; public void musicCd() { } [/CODE] Maybe because you are using the same name. I am not sure but you might want to test it

And to complete [I]rapture[/I]'s suggestion, try writing and TESTING small pieces of. Break down he assignment into small pieces of code and test them individually. You have written lots of stuff and you didn't explain what is the problem. I have noticed that you read and write from files. >Create …

The "mainMenu" should be the id of the table. Since you are using this: [ICODE]document.getElementById("mainMenu") [/ICODE] It is quite obvious when you say "getElement[B]ById[/B]" that the argument should be the id of the element you are trying to take.

Try this, although I am not sure since I have never used the "include" tag like this: [icode]<%@ include file="<%= somepage%>" %>[/icode]

[QUOTE=masijade;801982]Of course, but we need more info (as my first reply, sarcastically, implied).

First of all you don't say which tabs you couldn't do. Yes you did the Pool tab on your own, but which tabs you did and work and which don't work? So I would suggest to post the code of the tab that you are having problem with. ONE tab …

First of all the name of the select is: "selectPrimaryKey", so you will need something like this: [CODE] String nval=request.getParameter("selectPrimaryKey"); [/CODE] Also the select needs 1 minor change: [CODE] ............ <select name="selectPrimaryKey"> <option>SelectValue</option> <% for (int i = 0; i < Nheadlist.size(); i++) { %> <Option value="<%= Nheadlist.get(i)%>" > <%= …

Are both classes in the same folder?

Try changing this line: [CODE] rs1=stmt.executeQuery("insert into userinformation(username,password,dateofreg) values(username,password,dateofreg)"); [/CODE] To this: [CODE] rs1=stmt.executeQuery("insert into userinformation(username,password,dateofreg) values ('"+username+"','"+password+"','"+dateofreg+"')"); [/CODE] Also the exception tells you at which lines you got the error. It would be better if you point out to us which lines are that, because we cannot just count …

You have 2 while loops one inside the other that do exactly the same thing in the opposite. There are much better codes than that: [CODE] boolean done = false; while (!done) { // and now k2k's code enter input if (answer.equals("yes")) { do whatever calculations you want to do …

From a quick look at your code you have this: [CODE] case 2: mart.print(); // Call break to avoid falling through to the default case. break; [/CODE] It is suppose to print the shopping cart. Are you having problems with that?

Check the API for the String class. It has a replace method. Also if you search this forum you will find examples on how to read and writes files. So read the file line by line. For each line use the replace method and save the result (the modified line) …

Because when you do this: [CODE] String [][] array2D = new String[5][]; [/CODE] You don't create a 2-D array, but an [B]1-D[/B] array that takes as 'elements' arrays. So you can do this: [CODE] array2D[0] = new String[2]; array2D[1] = new String[10]; .... [/CODE] and access like: [CODE] array2D[0][0]; array2D[0][1]; …

Check the API for [URL="http://java.sun.com/javase/6/docs/api/java/util/ArrayList.html"]ArrayList[/URL].

Where do want it to be displayed because I don't think that it can be done. I would suggest you look at the API for PrintStream Because the System.out is type of PrintStream. This will behave exactly like the System.out.println [CODE] PrintStream print = new PrintStream(System.out); print.println("aaaaa"); [/CODE]

You need to count how many elements are inserted and when you reach 10 exit. If I understood correctly you will need this: [CODE] int count = 0; do { System.out.print("Enter 1 for F to C, 2 for C to F, and 3 to quit"); choice = input.nextInt(); if (choice …
