Hi Friend,

Try this:

import java.io.*;
import java.util.*;
import org.apache.poi.hwpf.HWPFDocument;
import org.apache.poi.hwpf.extractor.WordExtractor;

public class FileRead{
public static void main(String[] args) {
File file = null;
WordExtractor extractor = null ;
try {
file = new File("c:\\Hello.doc");
String st="";
FileInputStream fis=new FileInputStream(file.getAbsolutePath());
HWPFDocument document=new HWPFDocument(fis);
extractor = new WordExtractor(document);
String [] fileData = extractor.getParagraphText();
for(int i=0;i<fileData.length;i++){
if(fileData[i] != null)
st+=fileData[i]+" ";
}
StringTokenizer stk=new StringTokenizer(st," ");
while(stk.hasMoreTokens()){
String str=stk.nextToken();
if(str.indexOf('=')>0){
System.out.println(str);
}
}
}
catch(Exception ex){}
}
}

For the above code, you need Apache POI Library.

Thanks
