How to create n-new 2D arrays which hold the rows with the same index of n - 2D arrays

[barlet south]

Dear Friends,

I have been struggling into a problem on my java application and i need some help. I am trying to figure it out how to do it but i am not able to find a way and my brain now is off. What i have is some 2D arrays and each of them is rectangular and of the same size. So let say all are of the size (7X12). Those arrays we took from the method below AllSharesForFiles

// public class MyClass

AnotherClass s=new AnotherClass();
AnotherClass1 two=new AnotherClass1();
static shareHolder [] [] =null; // this is the field of this class

// some code here , some other fields and methods which are irrelevant with my problem

 public List<int[][]> AllSharesForFiles (int n , int k,List<File> file) {
	 
	  sharesHolder = new ArrayList<int[][]>();
	   try{	
	   
		for(int i=0;i<file.size();i++) {
	    		
	 byte[]secret = f.readingTheFile(file.get(i));  // We call the method which read the file
	    
	  
	  //method which evaluate the shares of each byte of the file   
	  shar1= s.calculateThresholdScheme(secret, n,k,new RndGeneratorAllAlgorithm(new RandomGeneratorSHA1()),two);
	 	System.out.println(Arrays.deepToString(shar1));
	  sharesHolder.add(shar1);
		}
	     
	   } catch (IOException e) {
	    	
	        e.printStackTrace();
	       
	               }	

	   return sharesHolder;
	}

// some code here

So the method above gives me an ArrayList of 2d arrays.Now what i want is to create from these 2D arrays new 2D arrays in which first new 2D array will have all first rows of my previous 2D arrays , the second new 2D array will have all second rows of my previous 2D arrays and so on .

If somebody has an idea of how to achieve it i will really appreciate a lot.

If you can use a List, why do you want to mess around with arrays?
Why have you marked that field static?
I think there is something wrong with your approach, and I think you should start by explaining what you are trying to do. That explanation will probably allow you to find a better solution.

Have a look at Arrays.deepCopy().

However, before you do that, re-read Campbell's post, because he speaketh sense.

What you really need to ask yourself is: Why do I need to do this?
