i need exercise java , don't know begin, told me should utilize stringtokenizer , have no thought how utilize or else on exercise. can of help me? i'm watching tutorials on java don't nil ...

the first step take string , alter list of words. can accomplished next code:

string initialstring = "..."; //whatever string string[] words = initialstring.split(" "); //split spaces word list

next, have open file can write words to. create instance of printwriter, constructor 2 parameters (the file name , encoding, utf-8). create printwriter next code:

printwriter write = new printwriter("output.txt", "utf-8");

just remember whatever file name specify printwriter overwritten!

finally, loop through list of words , write each 1 file modified for-loop:

for (string word : words) write.writeln(word);

and close writer:

write.close();

thus, final code looks this:

import java.io.printwriter; public class writewords { public static void main(string[] args) { //you can alter :) string sentence = "i using java text processing instead of perl."; string[] words = sentence.split(" "); //change "output.txt" whatever file printwriter write = new printwriter("output.txt", "utf-8"); (string word : words) write.writeln(word); write.close(); } }
