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!");
}
