First thing you'll need to do is to read in your text file and capture the data in a String .. I assume that each Shape will at least be on a different line in the text file.
Then you'll need to parse the String using the split command this will give you a sinle dimension array for each String. If you can get that far you'll be 90% of the way there.
Have a go at reading in the file first and if you are having problems post back.
Good luck,
Barry

What have you tried so far? You probably need to use FileInputStream, FileReader, or some other classes from the java.io package. That's where I suggest you start.

Keep Coding!

Are there any examples? I find that I learn best with example, else I just sit on a chair coding for hours, days, weeks without progress because I simply do not know what Im doing!

[Layne Lund]

Do you have a textbook? It should have plenty of examples. You may also want to see if the Java Tutorial has something appropriate to help you. Also, the links to the Java API documentation I gave above have a lot of helpful information, even if there are not full code examples.

No textbook, school is really crappy..

this is what i have so far:

public static void main( String[] args) throws IOException {
char[][] array = getArray( "c:\\file.txt" );
System.out.println("The contents in the file are:\n*****************************");
for( int loop = 0; loop < array.length; loop++ ) {
for( int innerLoop = 0; innerLoop < array[loop].length; innerLoop++ ) {
System.out.print( array[loop][innerLoop] );
}
System.out.println();
}
}
   
private static char[][] getArray(String fileName){
char[][] array = null;
BufferedReader reader = null;
StringBuffer buffer = new StringBuffer();// it is good rather then using str += "string";
try {
reader = new BufferedReader( new FileReader( fileName ) );
int rowsCount = 0;
// read lines into buffer, and count the rows.
String line = reader.readLine();
while(line != null){
buffer.append(line).append("\n");
rowsCount++;
line = reader.readLine();
}
array = new char[rowsCount][];// we have counted the rows.
int nlIndex = 0;// index of newline
// add rows in the array.
for(int loop=0;loop<rowsCount;loop++){
nlIndex = buffer.indexOf("\n");// get index of next line as we added as a mark.
char[] chars = new char[nlIndex];// create array
buffer.getChars(0, nlIndex, chars, 0);// read next chars
buffer.delete(0, nlIndex+1);// remove as we have got them
array[loop] = chars;// add into our array of array
}
} catch( Exception ex ) {
ex.printStackTrace(System.out);
} finally {
if(reader != null){
try {
reader.close();// don't forget to close the connection
} catch( IOException ioe ) {
ioe.printStackTrace(System.out);
}
}
buffer = null;// release buffer
System.gc();// it is good if there are a lot of contents, as it will collect the string buffer as well
}
return array;
}

I keep getting this error though, can someone please help me?

Error: cannot resolve symbol
symbol : class IOException
location: class ReadFileToArray

[C Ho]

hello?

[Stan James]

It may be as simple as adding an import at the top of the class ... right after package if you have one, right before class.

import java.io.IOException;

thanks
, now i can finally see how this makes sense
