Examples of java.io.StreamTokenizer.whitespaceChars()

java.io.StreamTokenizer.whitespaceChars()
Specifies that all characters c in the range low <= c <= high are white space characters. White space characters serve only to separate tokens in the input stream.
Any other attribute settings for the characters in the specified range are cleared. @param low the low end of the range. @param hi the high end of the range.
