643,983,104

A good answer might be:

Depends on context. This could be the tokens 643 and 983 and 104 separated by the delimiter comma, or it could be one token representing a large integer with thousands and millions marked with commas. Or it could be something completely different.

StringTokenizer Class

The StringTokenizer class aids in breaking a string into tokens. You can use the default delimiters, or specify your own. The default delimiters are: space, tab, newline, and carriage return.

StringTokenizer constructors
public StringTokenizer( String arg )

create a StringTokenizer based on String, using the default delimiters

public StringTokenizer( String arg, String delimit)

create a StringTokenizer based on String, using the individual characters in delimit as delimiters

public StringTokenizer( String arg, String delimit, boolean ret)

as above, but if ret is true, then individial delimiters count as tokens also.

Here is a tiny program that constructs a StringTokenizer from a command line parameter. The tokenizer will use the default delimiters. The program doesn't do anything, yet. 

import java.util.* ;

public class TokenTester
{
  StringTokenizer tok;

  public static void main ( String[] args )
  {
    if ( args.length > 0 )
    {
      tok = new StringTokenizer( args[0] );
    }
  }
}

The StringTokenizer class is found in java.util, which must be imported for the program to compile.

QUESTION 14:

Using the default delimiters, how many tokens are in this string: 

12  8  5  32
