class ReadTextFile
{
public static void main ( String[] args )
{
String fileName = "hockey pool.txt" ;
String line;
try
{
BufferedReader in = new BufferedReader(
new FileReader( fileName ) );
line = in.readLine();
while ( line != null ) // continue until end of file
{
System.out.println( line );
line = in.readLine();
}
in.close();
}
catch ( IOException iox )
{
System.out.println("Problem reading " + fileName );

here's a simple way
(if there's a lot of text, put the textarea into a JScrollPane
and give the scrollPans a preferredSize)
