Does anyone know if there is anyway i can declare an
array static so it holds it's value if i want to access
it from out of it's scope?
String filename
byte[] fileholder;
while ((character = fileinputstream.read(fileholder)) != -1){}
for(int k = 0; k < fileholder.length; k++){
String s = new String(fileholder);
System.out.print(s);}
// when the for loop executes nothing is printed becuase
i think the byte[] file holder is being accessed out
of it's scope. It's not that i need to print out the
contents of fileholder, i just need a way to fill it up
and be able to use it at a later time.

Placing the keyword "static" in the declaration will make that item "static", however, static means that all instances of a class will share this member's value(s).
Strictly speaking, "Global Scope" is a kind of no-no in Java (or true OOP), but the keyword "public" may give you what you need.
In fact, "public" in "public static void main(String[] args)" makes "main" callable by java.exe and "static" makes "main" callable without instantiating a "Test object" (instance of class Test).
//GlobalStuff.java
public class GlobalStuff{
public static String filename;
public static byte[] fileholder;
}
//Test.java
public class Test{
public static void main(String[] args){
GlobalStuff.filename = new String("Hello");
System.out.println(GlobalStuff.filename);
GlobalStuff.filename = new String("Good Bye");
System.out.println(GlobalStuff.filename);
}
}
BTW, I'd like to get a copy of the problem statement for htmlparser. Your teacher may be nicely describing the required components for a web browser. Right now, my main issue is with wrap around text/hyper-links.

I wish my teacher presented a clear specification of exactly what he wants in terms of this project.
I get what he whats but others in the class are kind of lost {{{laughing}}}. From what i get of what he is saying
all he wants is somthing that reads in a text file and parses out the tags only. Im comming to the end of a 17 month computer programming course at a local tech school so this really isnt any high level stuff if you know what i mean. I would have preferred doing a web browser project
myself but at this point i just want to finish this crappy course and split!

What exactly is meant by "parses out the tags only"? I saw some code where you were looking for "<", but are you concerned if it is a "<" within a tag but not a tag itself?
Are you just printing out the tags in the file or are you going to do something with the tags?
Will the output look like this:
Found Tags:
<HTML>
<HEAD>
<TITLE>
</TITLE>
<HEAD>
<BODY ??? What if there are attributes?
<IMG ???
</BODY>
</HTML>
Or will it just look like this:
Found Tags:
HTML
HEAD
TITLE
/TITLE
HEAD
BODY
IMG
/BODY
/HTML
