Coding error

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

thanks

Code java:

---

// 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);
    }
}

Hi chemy G,
a solution can be sort the array.
The code is

Code Java:

---

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
