    Default String Vector

    I have a vector of characters for example [e,m,a] but I need to have a String in which all characters are in a same word such as "ema", how should I change [e,m,a] to "ema"?

    Default String vector

    int ch;
    Vector<Character> result = new Vector<Character>(50, 10); 
    String[] Results ;
    		    while ((ch=inputStream.read()) > 0) {
    		    	result.add((char)ch);
    		 	}
    Results = new String[result.size()];
    Results= (String[])(result.toArray());
    it generates an error"[Ljava.lang.Object; cannot be cast to [Ljava.lang.String;"

    what should I do if I need to convert a vector of chars to an string?

    Default Re: String Vector

    Please don't post the same question in two different forums and please use [code] tags.

    You can use a StringBuilder object and add characters as you go. There's no need to read in the data if you already have it.

    // to append stuff to a StringBuilder
    // this code appends the character 'h' to the end of the StringBuilder object
    StringBuilder myStringBuilder = new StringBuilder();
    myStringBuilder.append('h');

    To get the character at each position on the Vector, use a for-loop across the size of the vector.

    for (int i = 0; i < myVector.size(); i++)
    {
         char theCharacter = myVector.get(i);
    }
