Could you please tell me the logic of printing a prime gap series within a given range i.e. 1 1 2 2 4 2 6....?

What I have tried:

int T,N,flag=0,i,j;
   Scanner scan = new Scanner (System.in);
    T = scan.nextInt();
    N = scan.nextInt();
   for(i=T;i <= N; i++)
   {
      for(j=2;j

The code you have provided is incomplete. Please edit your question and show us the actual code you have so far. Because, as is, this just seems like a "write down for me the part of my homework that I did not try to do myself" game. It's not a fun game for us, and it's a dangerous game for you if you are serious about learning development.

That is a mathematics question (and far from clear), not programming. Google will find you lots of white papers on prime numbers.

Naive approach: find the sequence of prime numbers 'in the given range' and print the differences between the consecutive ones.
