An program expects a string that contains the current time, such as "9:23AM" or "12:45PM" or "4:00 AM" Call the string time. How should the StringTokenizer be constructed?

A good answer might be:

StringTokenizer st = new StringTokenizer( time, ":AP", true )

Usually the input for a program comes from a file or from user input. StringTokenizer is useful in breaking this input into individual pieces of data. For example, say that a program is to add up integers, and that there may be several integers per line of input:

java addUp
Please enter the data:
12  8  5  32
The sum is: 57

This is more convenient for the user than requiring one integer per line. Here is an outline of a program that does this:

import java.util.* ;
import java.io.* ;

public class AddUp
{

  public static void main ( String[] args ) throws IOException
  {
    StringTokenizer tok;
    int sum = 0;

    BufferedReader inData = new BufferedReader 
        ( new InputStreamReader( System.in ) );

    System.out.println("Please enter the data:" );
    String inString = inData.readLine();
    tok = new StringTokenizer( _________________ );

    while ( tok._____________________() )
    {
      String intSt = tok._______________() ;
      int data     = Integer.____________( intSt );
      sum         += data;
    }

    System.out.println("Sum is: " + sum );
  }
}
