I have an byte array that contains the file data. For Khichidi-1 (224-bits), the byte array is divided into N 224-bit blocks, M(1), M(2) ,..., M(N) is there any inbuilt class in java to perform this operation. If there is none like that, then how can we create N no.of variables depending on the no.of message blocks

  • What do you mean by Khichidi-1? _ is there any inbuilt class in java to perform this operation_: What Operation? Commented Jun 21, 2011 at 5:34
  • If you want to create variables like M(1), M(2) ,..., M(N) then use array of M. ie <Type> M[] = new <Type>[N]; Commented Jun 21, 2011 at 5:36
  • khichidi is the name of the algorithm we are implementing. Operation means storing the N values in the byte array to N different variables Commented Jun 21, 2011 at 5:36
  • Is there any method to solve this. Can anyone provide a solution please help me Commented Jun 21, 2011 at 5:55
  • That is what arrays are for. Find what the size you need, and create an array of the size needed. See Collections also. Commented Jun 21, 2011 at 6:13

To create classes at runtime with Java you would have to use its reflection capabilities, see: http://download.oracle.com/javase/tutorial/reflect/index.html

However, I don't think that would help you in this case as the data you describe is simple raw bits of a particular length. You could divvy the data up into 28-byte chunks in an array of byte arrays.
