• It hides the details of the external data source or destination. • Java® allows you to treat some I/O distinctively, e.g. RandomAccessFile 7 Input vs Output Streams • Streams are unidirectional C# port of java's StreamTokenizer class. Everything kept same except some renaming for following C# naming convention.

like StreamTokenizer class. We will discuss about the StreamTokenizer class in I/O chapter. Constructors of StringTokenizer class The Java StreamTokenizer class (java.io.StreamTokenizer) can tokenize the characters read from a Reader into tokens. For instance, in the string "Mary had a little lamb" each word is a separate token. When you are parsing files or computer languages it is normal to break the input into tokens, before further processing them.

For tokens that are words, the nextToken method sets the sval field of the StreamTokenizer to the actual value of the token, and for tokens that are I wrote a grogram to read a text file in. for a line, read the first word in using StreamTokenizer and then the second char(a ":") and then using readLine to read the rest of the line in. the following loop is surposed to do this and the 1st iteration works well but then the StreamTokenizer doesn't work and the … StreamTokenizer. Many times when reading an input stream of characters, we need to parse it to see if what we are reading is a word or a number. This process is called "tokenizing".

The java.util.StringTokenizer class allows you to break a string into tokens. It is simple way to break string. It doesn't provide the facility to differentiate numbers, quoted strings, identifiers etc. like StreamTokenizer class. We will discuss about the StreamTokenizer class in I/O chapter. Constructors of StringTokenizer class.
