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?

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[].

suppose i wanna input my values in the accept function over the function over loading program, would the buffered reader syntax come under this function or the main function?

Can we use .split function in Boards ?

Guess please tell how to accept a. String or character through the method of Scanner please answer me fast till 8:05am becoz then I shall go to school leaving my phone at home so if see my question then answer me fast pleassssssse
