Message:

Now you can read your IP addresses

Posted by Kishori Sharan on December 11, 2000 at 11:32 AM

The StreamTokenizer is, by default, set to tokenize sophisticated java programs. So first thing you need to do is to reset the sepecialized synatax by calling resetSyntax ( ) method and set your own delimiter chars, white spaces etc. Here is the example which will read your IP addresses from text file. Just replace the file path C:\\kishori\\ip.txt to your own.

Thanx
Kishori

////////////////////C.java ////////////////
import java.io.*;

public class C {
private static StreamTokenizer st;
public static void main ( String[] args ) throws Exception {
st = new StreamTokenizer( new BufferedReader(new FileReader("c:\\kishori\\ip.txt")));

st.resetSyntax ( ) ;
st.whitespaceChars ( 0, ' ' ) ;
st.wordChars ( 33, 255 ) ;
String s = "";

while( st.nextToken() != StreamTokenizer.TT_EOF) {

if ( st.ttype == StreamTokenizer.TT_WORD ) {
s = st.sval ;
}
System.out.println ( s ) ;
}
}
}
