java - How to remove object from array -


Please understand it; Because it can be difficult to understand

I have a Jabatone 50 size big, for this example Ill use is 7 jbutton object within 7 I 1 2 3 4 6 7, but not 5. They are printed on the screen. I want to remove these jbuttons, but all 5 buttons are removed, while the last two are not. For <

  (int i = 1; i <51; i ++) {if (seat.buttonArray [i] == faucet) {remove (seat.buttonArray [i] ); Seat.buttonArray [i] = null;}}    
 
 
  Remove  element to  array , suppose that the subsequent indexes have been changed after the removal. For this purpose, you should use the  list :  
  Iterator Butitator = seat.buttonList.iterator (); While (ButtonErterator hasNext ()) {Object Button = Buttitter.Next (); // or more specific type, if your list is generated (button == blank) {// or some other criteria, it is written as an example example Iterator.remove (); }}   
 If it is mandatory to use  array , you have two options:  
     
  •  set  seat .buttonArray [i]  to the  null  value, it has been pointed out that it has been removed;  
  •  See Javadok for details, although I do not recommend this approach due to performance approaches.

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
