Program:

import java.io.*;       // import packages
import java.util.*;       // import packages
public class Sequence       // Class Sequence
{
   public static String input(char ch1,char ch2)   // Method input takes two char parameters ch1,ch2
   {
       String s1="";   // initialize string s1
       for(char ch=ch1;ch<=ch2;ch++)   // repeat from first character to last character
       s1=s1+ch;       // append characters between ch1 to ch2
       return s1;       // return s1
   }   // end input method
   public static void main(String[] args)    // main function
   {
       Scanner sc=new Scanner(System.in);   // object create for Scannet class
       char c1,c2;       // two char variables
       System.out.println("\nEnter First Character[a-z]/[A-Z]");   // display message
       c1=sc.next().charAt(0);   // read character from user
       System.out.println("\nEnter Second Character[a-z]/[A-Z]"); // display message
       c2=sc.next().charAt(0);   // read character from user
       System.out.println(input(c1,c2));   // call method and display result
   }   // end main funcion
}   // end class
