java - deleting an object from an array -

-

There is an array of objects of my custom class and I want to delete a random object (selected by certain criteria). How can I do this and order the array? Naturally, the elements will be transferred on the left side, but it is not enough to remove the element and I need help in preparing the argument. This is what I am doing but it does not work properly for this: ( 

  public static zero deletion record (customer [] record, intexide) {int pos = 0 ; // Indicator Boolean found = false; for (int i = 0; i & lt; count; i ++) {// If there is number of elements in the count (record [i] .get_accountid () == AccId) {Found = true; pos = i; break;}} If (found!) For System.out.println ("record does not exist") (int j = paus + 1; j & lt; count; j + +) {Record [J-1] = Rick [J];}    
 
 
 You can only move elements left because This will be overwrite items for deletion.  
  Generate public zeros (object [] A, index index) {for (int i = index + 1; i & lt; a.length Assume that the first  null   / Code> indicates the end of the elements.  
 Of course, this is the time of O (n) and the data structures such as Linkedlists are O (1) In summer you can remove elements.

qt - switch/case statement in C++ with a QString type -

-
I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.

Python's equivalent for Ruby's define_method? -

What is a Python equivalent for Ruby's define_method , which is the dynamic generation of class methods will allow? (As can be seen in Wikipedia) Functions are first-class objects in Python and assign them The properties of a class or an example can be a way of doing the same thing as a Wikipedia example: colors = {"black": "000", "red": "F00", "green": "0f0", "yellow": "ff0", "blue": "00f", "magenta": "fff", "cyan": "0ff", "white": " FFF "} Class MyStream (ARR): Pass for Name, Code in colors.iteritems (): def _in_colour ( W code = code): return '& lt; Span style = "color:% s" & gt;% s & lt; / Span & gt; ' % (Code, self) setter (histrive, "in_" + name, _in_ color)
