ICSE − Q & A

anyone awake :)

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 ?

Anybody going 2 burn midnight oil tonight???

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

What is valueOf fn.  used for and for what is parse fns.(like parseInt,parseDouble etc.) Used for???
Reply ASAP with examples plzzzzz?

Sdfg paper was too difficult I hope it comes easy paper tomorrow.
Atb to every one.

Somebody please upload selection sort and binary search program using bufferedreader
