Non-sequential shuffle.

Question

Hey all, I seem to be a bit.. stuck. I'm trying to make a program that takes a user defined integer from the command line, then prints it out in a shuffled, non-sequential order. Meaning, 4 cannot follow 5, and 9 cannot follow 8, etc. Here is my code thus far:
     int N = Integer.parseInt(args[0]);
          int[] song = new int[N];
     for (int position = 0; position < N; position++) {
         int list = position;
         song[position] = list;
        for (int current = 0; current < N; current++) {
         int swap = current + (int) (Math.random() * (N - current));
         int tempSong = song[current];
         song[current] = song[swap];
         song[swap] = tempSong;
         if (song[current] == (song[swap+1] || song[swap-1]))
          { randomize song[swap]; }
         else
          { System.out.println(song[swap]); }
     System.out.println(song[current] + " ");
     }When I go to compile it, it gives me the following two errors:
Shuffle2.java:22: ']' expected
          { randomize song[swap]; }
                           ^
Shuffle2.java:22: illegal start of expression
          { randomize song[swap]; }
                               ^
2 errorsAny help with this would be greatly appreciated.

Answer 1

I'm really just not getting it. I wanna say I'm almost there, but at the same point I just don't know.
     int N = Integer.parseInt(args[0]);
     int[] song = new int[N];
     for (int position = 0; position < N; position++) {
         int list = position;
         song[position] = list;
        for (int current = 0; current < N; current++) {
         int swap = current + (int) (Math.random() * (N - current));
         int tempSong = song[current];
         song[current] = song[swap];
         song[swap] = tempSong;
         if (song[current] == song[swap+1] ||
          song[current] == song[swap-1])
         else
          { System.out.println(song[swap]); }
     System.out.println(song[current] + " ");
     }I'm just lost as to what I put where the "**" is.
