In order to take a random number from the deck, you need to generate a random number that will be the cell of the array - deck[random cell] equals to a random card taken. Note that you need to know which cards have been already taken in order not to …

You sure that you put newImage.JPG in the proper directory? the second option is for relative path, you need to be sure that the relative path is correct.

How about you start and we will help?

Sounds like a perfect job for Google - give it a go right [URL="http://tinyurl.com/27hxrog"]here[/URL].

Ok, few problems that I can see: [LIST] [*]In line 16 you are creating an array [ICODE]int[] gradeArray = new int[sgrades];[/ICODE] when you didn't initialize sgrades - you need to retrieve the number of students in the class, which is the first line in the file. [*]In the loop in …

naief, perhaps your intention was good, but the purpose of the forum is to help and guide people toward the solution - just giving the answer is not the proper way to go. Writing bits of code and by that help in places of struggle is always welcome - but …

Accessing the first element of row i: [ICODE]arr[i][0];[/ICODE] Accessing the last element of row i: [ICODE]arr[i][arr[i].length - 1];[/ICODE] From here you just need to do the adding :) Give it a go, try to implement it.

Congrats, you have code. Do you have a question that comes with this code? Also, please use the code-tags when posting code.

Assuming that the code is [CODE=java]for i = 1 to 2 * n { j = i + 1 while j >= 1 { j = j – 1 } }[/CODE] Then let's analyze the complexity: The outer loop is simple, it goes from 1 to 2n, meaning 2n iterations. …

As jon.kiparsky said - if you want to show the user output you need to use the [ICODE]System.out.println()[/ICODE] method as you have used in your code in other places. You need to show the families with low income - use the [ICODE]System.out.println()[/ICODE] method in the if clause. Inside the if …

First, notice that you are handling objects, which are by reference. The code [CODE=java]PersonNode temp = current;[/CODE] Means that temp points to the location in the heap of current - changes that you are making for current will also affect temp! You will have to copy the object using a …

You didn't finish implementing all the methods yet, how do you expect it to work?

Integer.parseInt will throw an exception that you will have to catch - not a good practice.

[CODE=c]a=a+b; b=a-b; a=a-b;[/CODE] Will indeed swap to variables without a temp. Notice that you have to make sure that a+b does not exceed the maximum allowed integer. There is another way of swapping the variables without these constraints: [CODE=c]void swap (int *x, int *y) { if (x != y) { …

Problems that I can see here, first in the code in line 38: [CODE=java]if(Character.isLetter(j)) { p1array = phrase2.charAt(j).toCharArray(); }[/CODE] [ICODE]phrase2.charAt(j)[/ICODE] results in a char, and there is no such thing as [ICODE]toCharArray()[/ICODE] on char. The exact same problem occur in the if on line 49. Second problem is in the …

jon.kiparsky's approach of using a class member is the one that I would have used. There is another choice - in case you insist not to have class members, you can have your method return the String back to the main method, and from there you can send it to …

It states that you don't have a main method, meaning no method in the format: [CODE=java]public static void main(String args[]) { // something here }[/CODE] This is the method that is called first, and when it ends the program ends as well.

It's called Generics, and I think that [URL="http://en.wikipedia.org/wiki/Generics_in_Java"]this[/URL] will give you some sense into it :)

Take a look at [URL="http://www.daniweb.com/forums/post628847.html#post628847"]this[/URL] thread.

Let's take a look at [ICODE]makeFirstReservation[/ICODE] method: [CODE=java]public static void makeFirstReservation(int[][] totalSeats, Scanner input) { for (int row = 0; row < 3; row++) { for (int col = 0; col < 4; col++) { row = input.nextInt(); col = input.nextInt(); System.out.println(totalSeats[row][col]); } } }[/CODE] Every iteration of the inner …

You need to replace the %d with %f to print float numbers. [CODE=java]System.out.printf("%f\t\t%.1f\n",t, distance); [/CODE]

I don't see any question. What exactly is the problem?

Have you tried [URL="http://tinyurl.com/27eymzt"]here[/URL]?

You Bookcase array should be an ArrayList of books. Each cell in the array will contain a Book. Right now your book case just contains more book cases inside, instead of books. [CODE=java]public class Bookcase { public ArrayList<Book> mybooks=new ArrayList<Book>(); public Bookcase(String title, String author, String publisher, String isbn) { …

You can always implement copy constructors in your class: [CODE=java]public Class yourClass { public yourClass(yourClass yourClassObject) { //implement } }[/CODE] Other than that, you need to read the API about mutable and immutable objects to help you decide how to implement their copy in the constructor.

How about [URL="http://www.daniweb.com/forums/thread573.html"]showing some effort[/URL] first?

Explain the problem and your approach, don't expect everyone to guess what you need to do and code it for you.

Please use the code-tags when posting code. A String array is declared String[] purse = new String[the size of the array] So if you want the variable purse to be an array of size 100 the code will be: String[] purse = new String[100] Regarding the method `addCoin(String coin)` - …

After you have read the tutorials kremerd gave you, we will gladly help you. Just show us [I]your[/I] code, and where exactly you are stuck.

Or in simple words - please show some effort, and we will do our best to help and guide you :)

[LIST=1] [*]When you insert the values to the arrays, keep a counter - this way you will know what was the last cell that you have written to - at the end instead of [ICODE]RMSD_Final = R2 / coordinatesRotZ.length;[/ICODE] just do [ICODE]RMSD_Final = R2 / counter;[/ICODE] [*]The loop in line …

The recursion is checking all the possible permutations of the sources[] array. If you were given the task to write all the permutations, one approach would be to just: [LIST=1][*]Fix the number of the first letter. [*]See all the permutations of the n-1 letters remaining.[/LIST] To see the permutation of …

This thread is more than 5 years old, the OP had probably finished his PhD by now. Please open a new thread and leave old threads to die in peace.

You then can use peter_budo's method like this: [CODE=java]int[] varArr = getNumbers();[/CODE]

Ok, I will help you with part of your research and will direct you to the [URL="http://download.oracle.com/javase/6/docs/api/"]Java 6 API[/URL], specifically to the [URL="http://download.oracle.com/javase/6/docs/api/java/util/Random.html"]java.util.Random[/URL] class. This should help you with the creation of the Random numbers. After creating the random numbers, think how you make sure that the number generated is …

In your main method when you call [CODE=java]Rfc rfc =new Rfc(ip,80);[/CODE] You mean the ip you have declared inside the method but it is not reachable since it is inside the try code block - move all of the code inside the try block.

Then the least you can do is to mark this one as solved.

After you have finished adding all the contacts, then convert it into array, outside the loop is the right place :) EDIT: masijade beat me to it while I was typing :)

In your [ICODE]get_hours[/ICODE] and [ICODE]get_payrate[/ICODE], you are creating a new variable and sending it back. First, as kremerd said, you don't need to do that, since your intention is to return the global variable[ICODE] _hours[/ICODE]/[ICODE]_payrate[/ICODE] that you have already declared and initialized. What happens is called [I]Shadowing Declarations[/I], you can …

Well, the problem is because those are two different T's :) One is the class T, and the other one is the insert method's T. Let me explain - when you used the syntax [CODE=java]public <T> void insert(T item)[/CODE] You actually declared a generic method that uses the parameter T …

I remember that I tried to search for a solution but eventually excepted the warnings, and ignored them :) I understand how annoying those warnings can be, but if the code ensures that the types are the same, I don't think you should break your head to much around it.

This is like assigning a number to a char variable - it will interpret it as the ASCII value. As kremerd said - you need to convert them into a String.

Two extremely common questions are: Given a binary tree, reverse it, such that for every node x, swap x.leftChild and x.rightChild - analyse the complexity of your solution. Another one is similar - given a singly linked list, reverse the list. Analyse your complexity. A non-programming question - you are …

First of all, I think you better use the [Random](http://download.oracle.com/javase/6/docs/api/java/util/Random.html) class rather the `Math.random()`. If you want the game to continue until a certain condition is true, you can use the while loop: while(expression) { //do something } As long as the expression is true, the loop will continue. In …

First, excellent post - every experienced programmer is doing all of above and more after learning it the hard way - you cannot force your brain to work and solve all your problems, sometimes you need to rest, sometimes you need a different approach, and almost all of the time …

What have you done so far? Which part of the code you already have, and which part do you have trouble with?

Since you are retrieving the HTML code, you can parse the <a href = "HTML SITE> </a> tags in order to get the hyperlinks. What exactly do you mean by "parsing all the visible text from the particular web page"?

Can you please include the entire code?
