Streamtokenizer v príklade java

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

• When a number token is recognized, public member nval contains its value. • StreamTokenizer also ignores whitespace (blanks and tabs) and C, C++, and Java® style comments by default. C# port of java's StreamTokenizer class. Everything kept same except some renaming for following C# naming convention. And it also implements IEnumerable for foreach support - StreamTokenizer.cs StreamTokenizer.

StreamTokenizer defines four int constants : TT EOF, TT EOL, TT NUMBER, and TT WORD. Parses a stream into a set of defined tokens, one at a time. The different types of tokens that can be found are numbers, identifiers, quoted strings, and different comment styles. The java.io.StreamTokenizer.commentChar(int ch) method specifies that the character argument starts a single-line comment. All characters from the comment character to the end of the line are ignored by this stream tokenizer.

Transmit a password with MessageDigest Message digests are secure one-way hash functions that take arbitrary-sized data and output a fixed-length hash value.. A One-way hash function computes a number from a given data. There is no way to decrypt that number to retrieve its original value.

The stream tokenizer can recognize identifiers, … StreamTokenizer. In this chapter you will learn: How to use StreamTokenizer; nval and nval represent the next value; Set comment char for reading; Get line number; Use StreamTokenizer. StreamTokenizer breaks up the input stream into tokens. We create a StreamTokenizer from a Reader implementation and read input stream token by token.

This field contains the value of the number.

The parsing process is controlled by a table and a number of flags that can be set to various states. Introduction. The Java.io.StreamTokenizer class takes an input stream and parses it into "tokens", allowing the tokens to be read one at a time.

StreamTokenizer, 2 • When a StreamTokenizer recognizes a word, the public member sval contains the String representing the word. • When a number token is recognized, public member nval contains its value.

pubic class java.io.StreamTokenizer extends java.lang.Object{ //member elements public double nval;//If the current token is a number, this field is used. This field contains the value of the number. if the current token is a number the value of the tttype file is TT_NUMBER public String sval;//If the current token is a word, this field is used quoteChar() : java.io.StreamTokenizer.quoteChar(int arg) specifies that it delimits the matching character as string constant in StreamTokenizer. When the nextToken method encounters a string constant, the ttype field is set to the string delimiter and the sval field is set to the body of the string. The job of StreamTokenizer is to recognize sequences of characters that can categorized as identifiers, numbers, quoted strings, and comments. To do this, you must tell the StreamTokenizer how to categorize each character it might encounter: white space, alphabetic, numeric, string quote, and comment. * @see java.io.StreamTokenizer#quoteChar(int) * @see java.io.StreamTokenizer#TT_WORD * @see java.io.StreamTokenizer#ttype */ public String sval; /** * If the current token is a number, this field contains the value * of that number.

The Java StreamTokenizer class (java.io.StreamTokenizer) can tokenize the characters read from a Reader into tokens.

• 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.
