Is StringTokenizer faster?
This is because it is more robust and easier to use than StringTokenizer….Difference Between StringTokenizer and Split Method in Java.

|---|---|
| Because of this restriction, it’s about twice as fast as split(). | Slower than StringTokeniser |
| Consists of a constructor with a parameter that allows you to specify possible delimiter characters. | No constructor. |
What is use of StringTokenizer ()?
StringTokenizer class in Java is used to break a string into tokens. A StringTokenizer object internally maintains a current position within the string to be tokenized. Some operations advance this current position past the characters processed.

You can pass multiple delimiters e.g. you can break String into tokens by, and: at the same time. If you don’t provide any delimiter then by default it will use white-space.
What is difference between Split and substring in Java?
When you run this multiple times, the substring wins on time hands down: 1,000,000 iterations of split take 3.36s, while 1,000,000 iterations of substring take only 0.05s. And that’s with only eight components in the string! The difference for sixty components would be even more drastic.
