    Default Coding error

    I want the program to print the max and 2nd max value of an array of integers

    thanks
    // This program prints the maximum and the second maximum elemnet in an array
     
    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 = 0;
         int second = 0;  // 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 = 0;
         for (int i = 0; i < a.length; i++)
         {
           if (a[i] > first)
           {
              second = first;
              first = a[i];
           }
         }
         for (int j = 0; j < a.length; j++)
           {
             if (first > a[j])
             {
                second = a[j];
             }
           }
           //index ++;
         System.out.println("The maximum number is " + first);
         System.out.println("The second number is " + second);
        }
    }

    Default Re: Coding error

    Hi chemy G,
    a solution can be sort the array.
    The code is
    System.out.println( "Please input the array:  " );
    a =  ITI1120.readIntLine();
     
    Arrays.sort(a);
    first = a[a.length-1];
    second = a[a.length-2];
     
    System.out.println("The maximum number is " + first);
    System.out.println("The second number is " + second);

    Bye
