ICSE − Q & A

why is (index of )answer -1 if character is not found in string ?

Can anyone help me with the code of my previous question.... I'll tell the logic for that as well..... 
The logic is: If you take the numerical value of the letters, you find that they are in fibonacci sequence. And the second half is reverse fibonacci. Remember to take the numeric value instead of ASCII value. Good luck coding!

import java.util.*;
class isogram
{
    public static void main()
    {
        Scanner ayush=new Scanner (System.in);
        System.out.println("Enter a string");
        String s=ayush.nextLine();
        s=s.toUpperCase();String w="";String s1="";char ch1,ch2;int f=0;
        
        s=s+' ' ;
        int l=s.length();
        for(int i=0;i<l;i++)
        {
            char ch=s.charAt(i);
            if(ch==' ')
            {
                for(int j=0;j<w.length();j++)
                {ch1=w.charAt(j);
                    for(int k=j+1;k<w.length();k++)
                    {ch2=w.charAt(k);
                       if(ch1==ch2)
                       f++;}
                       if(f>0)
                       continue;
                       else
                       s1=s1+w+" ";
                    }}
                  else
                  w=w+ch;
                  w="";}
                  System.out.println("the stirng after manipulationm"+s1);}}

Compare a class as a user defined datatype and class as an application?
Ans: In Java, all functionality is enclosed in classes. But in order for a class to be user-defined datatype, it should be act different from that of an application. i.e. it should not include main() method in it. Although we can create instance of classes containing main method, they should not be referred to as used-defined datatype. Such classes (containing main() method) are more analogues to application than a datatype

trillion dollar question: whats the difference between Math.rint() and Math.round() in terms of functionality( I know that rint returns floating-point and round returns int;)
