java - Change an array to a string without creating a string -

-

I want to complete: 

  string [] beef = new string [3] ; Beef [0] = "water"; Beef [1] = "chicken"; Beef [2] = "paper"; String empo = Arrays.toString (beef); If (empo.isEmpty ()) {empo = "nothing"; Println (EMPO); } Else {System.out.println (empo); }   
 without creating a string.  
 
 Something like this:  
  string [] beef = new string [3]; Beef [0] = "water"; Beef [1] = "chicken"; Beef [2] = "paper"; Arrays.toString (beef); // Beef changes only on a plain string if (beef. Iseti ()) beef == "") {no = "nothing"; Println (beef);   
 How about going about this?   
 
 
 You can not.  
 JAVA is another type of language that means that you have to tell that when you declare it (strong typing), then what type of thing will you be, and you type that ) Can not change it anytime after.  
 You just create a new  string

I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.
