Note that StreamTokenizer(InputStream is) is deprecated. As of JDK version 1.1, the preferred way to tokenize an input stream is to convert it into a character stream, for example:
Reader r = new BufferedReader(new InputStreamReader(is));
StreamTokenizer st = new StreamTokenizer(r);
This code does what you want:
import java.io.*;
import java.util.StringTokenizer;
public class STTest
{
private String line = "";
private String[] lineOfTokens = null;
private StringTokenizer stringTokens;
public STTest()
{
try
{
BufferedReader br = new BufferedReader(new FileReader("testfile.dat"));
while ( (line = br.readLine()) != null )
{
stringTokens = new StringTokenizer(line, "()");
lineOfTokens = new String[stringTokens.countTokens()];
int x = 0;
}
catch (FileNotFoundException e)
{
e.printStackTrace();
}
catch (IOException e)
{
e.printStackTrace();
}
for (int i = 0; i < lineOfTokens.length; i++)
{
lineOfTokens[i] = stringTokens.nextToken();
}
for (int i = 0; i < lineOfTokens.length; i++)
{
System.out.println (lineOfTokens[i] + "\t");
}
}
public static void main(String[] args)
{
STTest sttest = new STTest();
}
}
