How's everybody doing tonight!
This is probably an easy question for some
of you to answer but im not sure of what to do.
If i compile this class i keep getting an "unreported
execption java.io.IOExecption; must be caught or
declared to be thrown.
while((character = bufferedinputstream.read()) != -1)
ok fine i understand that but if i change my main to
public static void main(String[] args) throws IOExecption{
i get cannot resolve symbol.
import java.io.*;
class htmlparser{
public static void main(String[] args){
int character;
int k = 0;
int i = 0;
byte[] hold = "Hello my name is brandon".getBytes();
char[] htmltagholder;
htmltagholder = new char[hold.length]; // htmltagholder array size is set to hold's size
ByteArrayInputStream in = new ByteArrayInputStream(hold);
BufferedInputStream bufferedinputstream = new BufferedInputStream(in);
while((character = bufferedinputstream.read()) != -1) {
if (hold[i] == '<') {
do{
System.arraycopy(hold,i,htmltagholder,k,1);
i++;
k++;
}while(hold[i] != '>');
} // the if statement
}
System.out.println(" The tags in your HTML file are: ");
for(int x = 0; x < htmltagholder.length; x++){
System.out.print(htmltagholder[x]);
}
}
}

Your posted code compiles with the following 3 changes:
public static void main(String[] args) throws IOException{
if (hold[0] == '<') {
}while(hold[0] != '>');
The index "0" for the "hold" byte array was just for a test. Check your logic for what it should be. I tried "character", but the index was out of bounds.
I'm also interested in writing a simple browser. Do you have thoughts on how to render images and text once the tags are known?

Hey thanks VirtuallyVB! maybe you should start charging
be by the post. {{{laughing}}} Yeah that code is just for some stupid project our teacher wants us to do to parse
out html tags from an incoming file. I could do it i 2
seconds in vb but in java im having trouble. Im not to sure how to render text and images once the tasgs are know. But i would like to find out....

That would be cool if you asked your teacher how to render them. I think I had the answer, but never tried it, so I don't know. I was concerned about placement (and maybe that needs further parsing of the tags with their placement fields within the tags).
Another thing, ask how to create a hyperlink in Java.
Perhaps we can take a Panel (named pagePanel) and add Labels for tags with text, but I still wonder if the alignment in the text tag (from additional parsing) would be sufficient to use as the alignment in a Label. I guess I have to code it to find out. Also an image tag could be the info for adding a Panel per image to the main Panel (pagePanel).
I'm starting to get motivated. I just can't think of how to add a hyperlink--wait--MouseOver event for a Label perhaps. Sswweeeet.
If you make the parser, let me know. I think I'll play with this within the next two weeks.
My idea is to make a browser that I can trust (unlike Commercial Browsers) and also a relay/proxy type browser.
Yeah, let me know if your parsing works out.
