Examples of java.io.Reader.reset()

java.io.Reader.reset()
Reset this Readers position to the last mark() location. Invocations of read()/skip() will occur from this new location. If this Reader was not marked, the implementation of reset() is implementation specific. See the comment for the specific Reader subclass for implementation details. The default action is to throw IOException. @throws IOException If a problem occured or the receiver does not support mark()/reset().

      
      read = reader.read(cc);
      assertEquals(6, read);
      assertEquals("brown ", new String(cc));
      
      reader.reset();
      read = reader.read(cc);
      assertEquals(6, read);
      assertEquals("brown ", new String(cc));
    }
    reader.close();
