Help?!

Please, why it doesn't work?

package lista.vetores;
import java.util.*;

public class Ex2 {
public static void main(String args[]){
Scanner sc = new Scanner(System.in);
float vet  [] = new float[15];
int i = 0;
float maior = 0;
float menor = 1000000;
while(i<15)
{System.out.println("input number":)
 vet [i] = sc.nextFloat();
 i++;
if (Arrays.binarySearch(vet, i)>M)
 {M = vet[i];}
 else {
 if (Arrays.binarySearch(vet, i)<m)
 {m = vet[i];}
        }
 }
System.out.println(" most of 15:"+M+" "+"smallest of 15:"+m);
 
}    
}

Some suggestions to help you get better help here:

• Please use a thread title that tells us something about the underlying nature of your problem. "help" tells us nothing we don't already know -- you wouldn't be posting a question here if you didn't need help. Think of the thread title as being similar to the headline of a newspaper article -- a single small sentence that summarizes all.
• Please explain just how your code is not working? Does it compile? run? give bad results?
• If you get any error messages, please post their full text.
• Please use [code] [/code] tags around your code so it retains its format and is readable.

Good luck and welcome here.
