Why scanner classes in java are not in 'jav.io' package?

Question

Why StringTokenizer and Scanner classes are not a part of java.io package but these belongs to java.util package?

Because neither requires IO operations. They both can operate on regular `String`s. — resueman, Jul 01 '16 at 13:23
InputStreamReader and BufferedReader altogether can operate on regular strings int the same way.Then why it was not included in java.io package — Priyankit Acharya, Jul 01 '16 at 13:27

Because they're utility classes and not fundamental for IO in any way.

please explain it.....as java.io package is for input and output purpose then why it was not included in java.io package – Priyankit Acharya Jul 01 '16 at 13:26
They are very useful helper classes which can be used as part of IO but are not primarily IO classes, it's a sensible abstraction. Having them in the IO package would be strange, since anybody using them for String parsing and manipulation would be mislead. – StuPointerException Jul 01 '16 at 13:31
