Reading a website in ISO-8859-1

Question

Hello
I am trying to read a website using the ISO-8859-1 charset.
I have searched a bit and found some different ways suggested for this. This is the one I think I want because it seems to be the simpler one.
byte[] iso88591Data = theString.getBytes("ISO-8859-1");But I don't understand the "flow" of the charsets:
1. When I read an html that has a #&<code> on it my string is in utf-8 or ISO-8859-1?
2. When the getBytes command is used, the specified charset is the one I want it to convert it to or the one it is in?
To understand this problem I did a separate class where I tried the following code.
import java.io.UnsupportedEncodingException;
public class charsetConversion {
     public static void main(String[] args) {
          String in = args[0];
          byte bytes[] = in.getBytes();
          try {
               byte bytesISO[] = in.getBytes("ISO-8859-1");
               String out1 = new String(bytes, "ISO-8859-1");
               String out2 = new String(bytesISO, "ISO-8859-1");
               String out3 = new String(bytes);
               String out4 = new String(bytesISO);
               System.out.println(out1);
               System.out.println(out2);
               System.out.println(out3);
               System.out.println(out4);
          } catch (UnsupportedEncodingException e) {
               e.printStackTrace();
}I run it with the input Poole&#x27 ;s and always get Poole&#x27 ;s. It doesn't have a space between 7 and ; but if I didn't write like that it always shows ' instead.
Don't really know what else to do.

So here is the example of the code
import java.io.BufferedReader;
import java.io.FileReader;
import java.io.UnsupportedEncodingException;
public class charsetConversion {
     public static void main(String[] args) {
          FileReader fr = null;
          BufferedReader br = null;
          String in = null;
          try {
               fr = new FileReader(args[0]);
               br = new BufferedReader(fr);
               in = br.readLine();
          } catch (Exception e) {
               System.out.println(e.getMessage());
               System.exit(0);
          byte bytes[] = in.getBytes();
          try {
               byte bytesISO[] = in.getBytes("ISO-8859-1");
               String out1 = new String(bytes, "ISO-8859-1");
               String out2 = new String(bytesISO, "ISO-8859-1");
               String out3 = new String(bytes);
               String out4 = new String(bytesISO);
               System.out.println(out1);
               System.out.println(out2);
               System.out.println(out3);
               System.out.println(out4);
          } catch (UnsupportedEncodingException e) {
               e.printStackTrace();
}As an argument I pass the file. I use this instead Inside the file I have
Poole&#x27 ;s   (without the space)Without attaching a file it's hard to use the html
