  Understanding copying multidimensional arrays in Java
  
  Before you begin the process, you need to understand in detail as to what is copying multidimensional arrays in Java and why it is important to do this. There may be other methods for copying multidimensional arrays in Java but the one given below is just a basic version that can help you identify the process. Giving an example of Java computer programming and multidimensional arrays, you need to understand this chart in detail.
  
  for(int k = 0; k < Nz; k++){
  
  for(int j = 0; j < Ny; j++){
  
  for(int i = 0; i < Nx; i++){
  
  grid_copy[i][j][k] = grid[i][j][k];
  
  }
  
  }
  
  }

  Depressingly low level and anti DRY
  
  You also need to understand in detail that for every array in Java computer programming, the depressingly low level and anti DRY array need to come first before multidimensional arrays. The generic copy of multidimensional arrays will follow. Though this precise work can only done by a computer language professional, but still with basic information and guidelines, you will certainly will able to complete the task up-to a certain level.

  Private void copy
  
  (Object source, Object dest) {
  
  if(source.getClass().isArray() && dest.getClass().isArray()) {
  
  for(int i=0;i
  
  if(Array.get(source, i) != null && Array.get(source, i).getClass().isArray()) {
  
  copy(Array.get(source, i), Array.get(dest, i));
  
  } else {
  
  Array.set(dest, i, Array.get(source, i));
  
  }
  
  }
  
  }
  
  }
  
  The method given above is not a professional way of copying multidimensional arrays rather a very general form of doing it correctly. Though it is a solution, but still you need to make sure that you follow the methods and procedures which match with whatever your needs are. This is just a basic guide to help you get started and can be used as a template if you get stuck.

  Recursive approach
  
  Some developers say that it is a recursive approach as you are not directly copying multidimensional arrays but rather it is an application that comes with specific instructions.
