*) New characters will be formed after skipping the N (position value MOD 10) char forward. A->A+1= B , B->B+2=D ,C->C+3=F, .... Y->Y+(25%10)->Y+5=D

Answer 1

import java.util.Scanner;
class Encrypt
{
public static void main(String[] args)
{
    String alphabets="ABCDEFGHIJKLMNOPQRSTUVWXYZ";
    Scanner input=new Scanner(System.in);
    System.out.print("Enter text to encrypt: ");
    String text=input.next();
    String output="";
    int pos;
    //encrypt the given data
    for(int i=0;i<text.length();++i)
    {
      pos=(alphabets.indexOf(text.charAt(i)));
      pos=((pos+1)%26+(pos+1)%10);
      if(pos>26)
      pos=pos-26;
      output=output+alphabets.charAt(pos-1);
    }
System.out.println("Encrypted text: "+output);
}
}

Output
