Answer ASAP
1)How,where is lvalue of a variable stored?How can it b accessed?
2)Can v say that the subscripted variable of an array's elements r their lvalues?
3)Does neew operator provide an unique vaue to lvalue of every instance we create in our program?
4)In Sumita Arora seperators n delimiters r not mentioned as tokens but in APC ,they r?Can some1 clarify?
5)does call by reference pass the lvalue of actual parameters?
6)Dooes call by reference always require composite data type?
7)Does call by value require the rvalue of actual parameters?
I know its a bit late but plz reply.

Guys try this logic for Fascinating Number; I've broken down the program into bits so that it'll be easier to comprehend. Its done using Strings,Arrays,Sorting and checking...

import java.util.*;
class Fascinating
{
    public static void main()
    {
        //accepting
        System.out.println("Enter Number: ");
        Scanner sc=new Scanner(System.in);
        int n=sc.nextInt();
        String temp=Integer.toString(n*1)+Integer.toString(n*2)+Integer.toString(n*3);
        int[]a={1,2,3,4,5,6,7,8,9};
        char[]ch=temp.toCharArray();
        
        //sorting
        for(int i=0;i<ch.length-1;i++)
        {
            for(int j=0;j<ch.length-i-1;j++)
            {
                if(ch[j]>ch[j+1])
                {
                    char aa=ch[j];
                    ch[j]=ch[j+1];
                    ch[j+1]=aa;
                }
            }
        }
        
        //counting
        boolean b=false;
        int count=0;
        for(int i=0;i<ch.length;i++)
        {
            
            if(ch[i]==0)
            continue;
            
            else 
            {
                if(((int)ch[i]-48)==a[i]){
                b=true;
                count++;
            }
                
                else 
                b=false;
            }
        }
        
        //printing
		if(b==true&&count==9)
		    System.out.println("Fascinating Number!");
		else
		System.out.println("Not Fascinating Number!");
}
}

any1 still alive........i mean awake.[lol]
now the doubt ...explain Sring args[].
