String of boolean values to an array?

Question

I created the code below to print out all of the values of a string to 'true' or 'false'. I would like to fill an array with all the printed values "True true false true...." Right now when I print out the values of the String str if it is not in the loop I only get the first value of the first character.

    // First find out how many words and store in numWords
    // Use "isDelim()" to determine delimiters versus words
    //
    // Create wordArr big enough to hold numWords Strings
    // Fill up wordArr with words found in "phrase" parameter
    public void Parse(String phrase) {
      int len = phrase.length(); 
      String str = null;

      int isTrueCount = 0;
      int isFalseCount = 0;

      for (int i = 0; i < (len); i++) { 
        str = String.valueOf(!isDelim(phrase.charAt(i)));
        System.out.println(str);

        if (str == "true") {
          isTrueCount++;
        } else {
          isFalseCount++;
        }
      }
      System.out.println(isTrueCount);
      System.out.println(isFalseCount);
    }

Length of len is any arbitrary string/text file/keyboard input. I am hoping to use the true and false values within an array to pick out the true number of words from delims.

You're over-writing the String with each iteration of the loop. Perhaps you want to do str += String.valueOf(foo) + " ";. Better still, don't create a String at all, but add the results into an ArrayList<Boolean>. — Hovercraft Full Of Eels

Maybe you can explain what you are trying to do. Forget about the algorithms and the loops. Just what is the goal? You have a string, and what do you want to do? Count delimiters? Count characters? — Steve J

Don't use Strings for this as it adds unnecessary complexity. Simply increment your variable if the statement is true:

  for (int i = 0; i < phrase.length(); i++) {
     if (!isDelim(phrase.charAt(i))) {
        isTrue++;
     } else {
        isFalse++;
     }
  }
