Reading into ArrayList problem - what is wrong?

Question

Hi, I am trying to read a list of strings into an ArrayList and am having some problems. I have created a main() which at the moment does nothing, its just to make sure that the array's content is genuine (meaning consistent with the string in the text file) so I am having it simply printed out to screen. The error I am getting is "cannot resolve symbol, variable array" by my compiler (Jcreator). I will paste the code below:
import java.io.*;
import java.util.*;
public class hostList{
public hostList()
try
File input = new File("hosts.txt");
BufferedReader in=new BufferedReader(
     new InputStreamReader(new FileInputStream(input)));
     ArrayList list=new ArrayList();
     String line;
     while((line=in.readLine())!=null)
          list.add(line);
     String[] array=new String[list.size()];
     list.toArray(array);
     in.close();
catch(FileNotFoundException e)
System.err.println("File not found...");
catch(IOException e)
System.err.println("IO Problem");
}//hostLst()
     public static void main (String [] args){
          System.out.println("Array content:");
          System.out.println("array " + array[0]);
          for (int i=0; array[i] !=null; i++)
               System.out.println(array);
     }//main
}//class
Also, how would I use the array objects in another class, say class B. How can I access the arrays in class B so that i can use its methods? eg. array[i].doSomething(); where doSomething() is a method in class B. What libraries would i need to import (if any) ?
Help is appreciated, thanks.

Answer 1

this code wont compile bcas in main method u r not creating the object of this class also the var array is not globally declared hence wont be accesibile outside
u can try this modified code
import java.io.*;
import java.util.*;
public class hostList{
String[] array=null;
public hostList()
try
File input = new File("hosts.txt");
BufferedReader in=new BufferedReader(
new InputStreamReader(new FileInputStream(input)));
ArrayList list=new ArrayList();
String line;
while((line=in.readLine())!=null)
list.add(line);
array=new String[list.size()];
list.toArray(array);
in.close();
catch(FileNotFoundException e)
System.err.println("File not found...");
catch(IOException e)
System.err.println("IO Problem");
}//hostLst()
public static void main (String [] args){
hostList h=new hostList();
System.out.println("Array content:");
System.out.println("array " + h.array[0]);
}//main
}//class
