This is code I'm currently working on learning about ciphers, I'm still missing a few requirements and one requirement is that I need to be able to discard the first 3072 bytes of the pseudo random numbers generated. How should i go about doing this? An explanation would also be very much appreciated, thanks.

package rccipher;

import java.util.Scanner; import java.io.BufferedReader; import java.io.FileReader; import java.io.IOException;

public class RCCipher {

static void output(int disp[]) { char con[]=new char[disp.length]; for(int l=0;l
