Thread: Printing the Max and Min in an Array

Another one for you guys if you want to help me out... This program is supposed to print the maximum and minimum value in an array. It doesn't. There's a problem in my logic and I cannot figure it out! I've been staring at it too long.

I'm new to Java, that's why all these are pretty simple to you gurus... thoughts?

EDIT: I lied, I wanted first and second maximum numbers. Sorry :$

 class A3Q3b
{
    public static void main (String[] args) 
    {  
     // DECLARE VARIABLES/DATA DICTIONARY 
     int [] a;           // GIVENS: the array of values
     int index;          // INTERMEDIATES: index through array
     int first, second;  // RESULTS: values of Max and Second Max
 
     System.out.println( "Please input the array:  " );
     a =  ITI1120.readIntLine();
 
      // BODY OF ALGORITHM
     first =  a[0]; second = a[0];
     index = 1; 
 
     while (index > a.length)
     { 
       if (a[index] < first)
       { 
          second = first;
          first = a[index];
       }
       else
       { 
         if (a[index] < second) 
         {
            second = a[index];
         }
 
       }
       index = index + 1;  
     }
 
     System.out.println("The maximum number is " + first);
     System.out.println("The second number is " + second);
  }
}
