In this tutorial how to get details of a file using StreamTokenizer class in Core Java\u00a0 is shown.<\/p>\n
Code:<\/p>\n
StreamTokenizerDemo.java<\/p>\n
import java.io.*;<\/p>\n
public class StreamTokenizerDemo
\n{
\npublic static void main(String args[]) throws IOException
\n{
\nFileReader freader = new FileReader(“Demo.txt”);
\nStreamTokenizer st = new StreamTokenizer(freader);<\/p>\n
double sum=0;
\nint numWords=0,numChars=0;<\/p>\n
while(st.nextToken() != st.TT_EOF)
\n{
\nif(st.ttype == StreamTokenizer.TT_NUMBER)
\n{
\nsum+=st.nval;
\n}
\nelse if(st.ttype == StreamTokenizer.TT_WORD)
\n{
\nnumWords++;
\nnumChars+=st.sval.length();
\n}
\n}<\/p>\n
System.out.println(“Sum of total number in the file: “+sum);
\nSystem.out.println(“Total words in the file: “+numWords);
\nSystem.out.println(“Number of characters available in words: “+numChars);
\n}
\n}<\/p>\n
