I want to increase my knowledge of PHP by learning about classes. I wrote the following very simple test program. It works. But I would like to know improve it. I plan on writing more complex test programs and that won't be the time to iron out smaller issues. Thanks in advance. <?php $length = array_key_exists('length', $_POST) ? $_POST['length'] : null; $width = array_key_exists('width', $_POST) ? $_POST['width'] : null; if ($length == "") $length = 0; if ($width == "") $width = 0; ?> <?php class Shape { var $length; var $width; function setLength($Length) { $this -> length = $Length; …

Hey guys! I am trying to map the following dictionary <int,List<T>>. I am trying to get the i-th permutation of an input array, the List<t> being the i-th perm itself. If I have: Input Array [1,2,3], the 0-th perm would be [1,2,3], the 1-st [1,3,2] and so on... So, so far, the Dict would have {[0,{1,2,3}] , [1,{1,3,2}]}. All sounds great, but after i reach i = 2 and need to carry on, I just don't seem to be able to get the next permutation list back! Help! public class LehmerCode<T> { public LehmerCode() { } private List<int> GetFactorial(int nthPerm, …

Greetings, I'm working on a class project for fractions and I'm stuck and cannot figure out where to go from here. We have a mandatory driver file we aren't supposed to change.

One of my assignments, that I already turned in, dealt with collecting a student's name and gpa, and storing the information in an array. Afterwards, we were asked to display the student's information in descending order based on their gpa. I was curious if anyone has any suggestions on improving the code. This is my student class: /** Define a class Student. Each student is defined by: * a string name * a floating-point GPA */ import java.util.*; import java.text.DecimalFormat; public class Student { private String name; private double GPA; //to enter the data for a new student public Student() …

I know this has been asked before, but I can't find any simple answers for a noob like me in C#. What exactly is a static method. I mean what does it mean to be static vs. nonstatic. I know in the code with the main method we use `public static void Main(string []args)` what does the static change about the main method that distinguishes it from the rest in regards to it being static. - Thanks

**Introduction** Hi guyz today I am going to writing a tutorial on dictionaries in Python....As per as getting comments from my readers I'll try to make this tutorial short.... **Layout** 1.What are dictionaries? 2.Why dictionaries? 3.How to declare/make dictionaries in Python? 4.What all you can do with a dictionary? 5.Interesting Functions? 6.Dictionary Methods? **What are dictionaries?** Dictionaries are simply another type of Sequence in Python.. Like in English dictionaries you search for a word and its meaning … Same happens in python... Dictionaries in Python have a “key” and a “value of that key”... That may seem strange for the …

Hello good afternoon. I have successfully serialized data in the past, however it seems as if I don;t fully understand the process. I have a class called ProgramState which stores a variable (called lastCreated) with custom class LinesProject and an ArrayList variable(called recentProjects) of this custom class. The purpose of these variables is to store the last created project as well as a list of five recently opened projects. Here is ProgramState: public class ProgramState implements Serializable{ private LinesProject lastCreated; private ArrayList<LinesProject> recentProjects; public ProgramState() { lastCreated=new LinesProject(); recentProjects=new ArrayList<LinesProject>(); } public ProgramState(LinesProject proj) { lastCreated=proj; recentProjects=new ArrayList<LinesProject>(); } //Setters …

Hello I am trying to create a class that called Lootable and create subclasses such as trunk, locker, etc. that will contain items that can be looted, they will inherit their lootability from the Lootable class. I am thinking of using the ArrayList for this. I have thought of different ways to go about this and have written some code but I am having some difficulties. This is for and assignment and my app idea goes somewhat beyond the requirements of the lesson and no I do not expect someone to due this for me I would however like some …

I'm trying to create a list stack that implements some interface called SomeList The list stack should only use stack with no links. the itnerface has a number of methods that I would like to implement. So for SomeList I have something like public interface SomeList<T>{public void plus(T something);public E takeout(int somewhere); and so on} For the generic ListStack I have something like public class ListStack<T> implements SomeList<T>{ Stack<T> stack1=new Stack<E>(); //constructor public LinkStack(){ stack1=new Stack<T>(); } //method public void plus(T somethig){ this.push();} . . . } In the method above (plus(T something)) I get an error on push.

Hello, I'm trying to program a basic program at the moment and have run into some difficulties. I have a method as follows: public static void loadDB() { // load data into datasets - this will be called on form2 the login screen loadTblStaff(); loadTblCars(); } the method is called on another form on load. The methods its supposed to call are as follows: public static void loadTblStaff() { // prepare, open and load the staff table into dataset ds2 con.ConnectionString = dbProvider + dbSource; MessageBox.Show("loadTblStaff() called"); con.Open(); MessageBox.Show("load table staff connection opened"); sql = "SELECT * FROM tblStaff"; ds2 …

Hey Guys, So I was doin a tutorial and I incorporated it into my code and it works for the most part. The program gives you a list of town names you pick one and hit search. All good so far then the program goes into the database and pulls the relevant info from 6 tables and they display in the next gui on a Jtable. Only problem is the column header are taken from the database aswell but I want Generic column titles as the ones from the table reflect the table they were pulled from and since there …

Hey everyone, I am having trouble on this one practice problem. It is a question that requires another question I already completed to solve this one. The qusetion is "Implement a method allPerfect() that takes an integer parameter end. The method prints every perfect number from 1 to end. Use the method isPerfect() above to check if a number is perfect. " I am confused on how to use isPerfect to check if the number is perfect or not. Any help would be greatly appreciated.

Hi there, Today, I had a chat my lecturer about instance methods and static methods. I thought you make methods with static modifier (let me know in the comments below if I'm wrong) if you want to access them without creatng an instance of the class which they're defined in. I found in C# if you're creating static methods, you won't be able to access them using the keyword 'this'. But you can still have access to instance methods through the 'this' word. Is there any difference between those types of methods?

I have started writing a *really* basic tile engine in C++ and I'm not entirely sure when to use const return values. Should I use them in cases like this class A { private: Rectangle hitBox; public: A(); const bool Collision(const Rectangle& hitBox2); }; or is it totally pointless?

i'd like to change my code from procedural to OOP and i've got a problem when it comes to naming methods. can somebody explain to me what's wrong with this - sort.java:36: ';' expected public static int sortAscending () { - i understand that semicolon is not needed sort.java:36: illegal start of expression public static int sortAscending () {

Hi everyone, I am brand new to Java and I like it a lot so far. I am very stuck on an assignment for school that I need help with. We are just learning about method invocation, how to write and call methods in Java. My program should take user generated input for a radius value and output the volume, area, and radius of a sphere in a dialoge box. The Output/Input classes are just classes my professor wrote to allow us a pretty interface (we haven't used sys.out.println yet). I cannot get my method invocation to work. The compilation …
