how to match the key word from a text file

Posted in : Java Beginners

p>Hi all, I have the code to match the key word and from the text. I have input like this reader.txt

Guindy National Park is located in Chennai , South India , one of the last remnants of tropical dry evergreen forest of the Coromandel Coast , Guindy Park was originally a game reserve.

and 2.txt is located biosphere reserve

I am getting an output like this now. Number of times Tim is: located Number of times Tim is: serve

the expected output is Number of times Tim is: located

code is as follows
**import java.io.*;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
class Classnew
{
public static String getnew()
{
String data2 = "";
try {
String devstr;
while ((devstr = br.readLine()) != null) {
System.out.println(devstr);
data2+=devstr+"\n";
}
} catch (IOException e) {
}
return data2;
}
}
public class Findwordphrase {
public static void main(String[] args) {
Classnew classnew = new Classnew();
String data2 =classnew.getnew();
System.out.println("Data of Class2(keyWrd): " + data2);
try {
String devstr;
while ((devstr = br.readLine()) != null) {
String text = devstr;
String text1 = text.replaceAll("  ","").replaceAll("   "," ");
System.out.println(text1);
String[] words = text1.split(" ");
for (String word : words)
{
String regex1 = "\\b"+data2+"\\b";
Pattern pattern1 = Pattern.compile(regex1);
Matcher matcher1 = pattern1.matcher(word);
String val = null;
while (matcher1.find()) {
val = matcher1.group();
System.out.println("Number of times Tim is: " +val );
}
}
}
} catch (IOException e) {
}//try catch ends
}
}**


If i give the input like this String regex1 = "\blocated|reserve|biosphere\b";

instead of this i am getting the result. I don't want to hard code the string. instead i want to get the value from the called file and get the result. String regex1 = "\b"+data2+"\b";

i am missing some part to get the correct output and not able to find that. If any one could find my mistake help me. please...
