Whats wrong with this?

Code:

---

import java.io.*;

public class sortem{
  public static void main(int args[]) throws IOException {

        int i=9, min=100, prevMin=0;

        while (i > 0)
        {
        int index=9;
                while (index >= 0)
                {
                        if ((args[index] < min) && (args[index] > prevMin))
                                min = args[index];
                        index--;
                }
                System.out.println( min );
                prevMin = min;
                min = 100;
                i--;
        }
}
}

I don't have Java here, so I can't test the code. But you seem to be doing a sort on 9 numbers entered through command line arguments. What problems are you facing?

Two possible reasons could be accepting an int array instead of a String one in the psv main method, and typecasting the array elements when comparing or assigning.

.

honeybee is rignt you would have to change the parameter of the main method to take a string array instead of an int array.
Your program will compile fine with the int array in the main method but a java.lang.NoSuchMethodError will be prooduced at runtime.

Once you change the int array into a String array i would use the parseInt() method from the Integer class for the comparison.

Code:

---

if ((Integer.parseInt(args[index]) < min && Integer.parseInt(args[index]) > prevMin);
