As an illustration of what Tor is describing:

import java.io.*;
import java.net.*;
import java.util.*;
import java.util.regex.*;

public class ClassNameParser
{
public static void main(String[] args)
throws IOException
{
String fileName = args[0];

Pattern p = Pattern.compile
("\\Wnew\\s+([_a-zA-Z][_a-zA-Z0-9]*)");

BufferedReader in =
new BufferedReader(
new FileReader(fileName));

while (true) {
String line = in.readLine();
if (line == null)
break;
Matcher m = p.matcher(line);
while (m.find()) {
String className = m.group(1);
System.out.println(className);
}
}
}
}
