tokens to string

[hello12]

I am a newbie at Java. I am doing an assignment on string manipulations. Can anyone give me tips on how to make tokens back into a sentence.
Eg.
Good ------>(to) Good Morning Everyone!!
Morning
Everyone!!
thanks in advance

Do you have the words/tokens in an array or in a StringTokenizer ?

StringTokenizer .

[Ganon11]

So you have a StringTokenizer whose contents are "Good", "Morning", and "Everyone!"

Make a new String variable set to the empty string "". While your Tokenizer has more tokens, append the nextToken to the end of your String, plus a space.

Yes try that and post your code (using code tags) if you get any problem.

I tried the code it's working but there is a problem..
I tokenized the sentences from a file
Hello World
Good Morning Everyone!!
I was suppose to reverse each word and output the result: right now i am
getting
olloH dlroW dooG gninroM !!enoyrevE ( how do i make this into 2 different lines like in the file)?
try{
BufferedReader Buf = new BufferedReader( new FileReader(File name));
String line;

while((line = Buf.readLine()) != null){

StringTokenizer token = new StringTokenizer (line);
int number = token.countToke ns();
while(token.has MoreTokens()){
String word = token.nextToken ();
String hold = (reverseFunctio n(word));
StringTokenizer tok = new StringTokenizer (hold);
var += (tok.nextToken( )+ " ");


}
System.out.prin tln(var);
System.out.prin tln(number);


}
Thanks for the help

sorry i forgot the documentation part
try{
//reads from file
BufferedReader Buf = new BufferedReader( new FileReader(File name));
String line;

while((line = Buf.readLine()) != null){

StringTokenizer token = new StringTokenizer (line);
int number = token.countToke ns();
while(token.has MoreTokens()){
String word = token.nextToken ();//Tokenizes the file

String hold = (reverseFunctio n(word));// calls a function to reverse words//
StringTokenizer tok = new StringTokenizer (hold);
var += (tok.nextToken( )+ " "); //combines the word to form the sentence


}
System.out.prin tln(var); //prints out the new sentence
System.out.prin tln(number);


}

If your input file has the words in two seperate lines, you can repeat the following process for each line:

1) Get the next line from your input file.
2) Make a StringTokenizer with the input string.
3) Reverse each token and hold in a larger string variable.
4) Output the larger string variable

This will reverse each word in each line individually, rather than the whole file.

I don't see why you are going through the trouble of the tokenizer. Why not just

 while((line = Buf.readLine()) != null){ 
      String hold = reverseFunction(line);
      System.out.println(hold);
}

this is my first asiignment i was kind of exploring different types and methods.. i guess :)
