Examples of java.util.StringTokenizer.countTokens()

java.util.StringTokenizer.countTokens()
Calculates the number of times that this tokenizer's nextToken method can be called before it generates an exception. The current position is not advanced. @return the number of tokens remaining in the string using the currentdelimiter set. @see java.util.StringTokenizer#nextToken()
