Loop Scanner

Java Array while loop and Scanner class?

I’m trying to let the user enter a line of code and have all the ‘words’ that are seperated by whitespace entered into an array. The problem I’m having is that the this example never prints the test statement when it’s done. Not sure what it’s doing, it’s not looping (I checkd with a test output in the wile loop).

public static void main(String args[]) {
//Put them on a list.
final List list
= new ArrayList();
String str = “”;

Scanner token = new Scanner(System.in);
//While $ is not entered, accept String.
while (! (str = token.next()).equals(”$”)) {
list.add(str);
}

//Print them out
for (String text : list) {
System.out.print(text + “,”);
}
}

Fax (Fax) Machines are a source of sending copies to the most distant from the telephone line, which today are sent through servers. The great advantage that it Fax is independent of instantaneous data transfer. The fax machine is composed of a scanner and a modem. Some machines are equipped with fax printer and photocopier. The image scanner scans the image and the modem translates the data into a coded message and sends it along the line, which then reproduced in the receiving terminal.

Fax machines are basically of two types, analog fax machine and digital Fax machine. In developing this technology was invented a century earlier, analog fax machines were used. Although the machine was invented long ago but that has gained popularity in recent years with more advances in technology and lower cost. Today Digital fax machines have replaced almost Devices fax machines.

The Digital fax initially started in Japan, and has now spread throughout the world. And from the time the Internet has entered the field this machine has come into vogue. Servers fax setting in which data is sent in digital form through the local loops and digital subscriber lines. As the data is sent in digital format so now can be easily modified to reduce the time it takes to send a page.

The original data is compressed and encrypted in a new form of data, which is then divided into small packets of information and sent through the Internet server to the other machine. The other machine decodes and decompresses these data and prints the original document as it is. That is why the digital fax machine when considering the speed of delivery has an advantage. And so, the machines are often classified on the basis of time it takes to send data.

Usually two methods of data compression is used, are the codification of Hoffman and Differential Manchester encoding. In Hoffman encoding each word is compressed with an algorithm and the blanks are excluded, then the message is also encoded and sent. Differential Manchester While a single line of code is scanned and encoded at a time, which is then compared with the success of encoded scan line, and that this difference is sent through the server.

At the terminal receiver the demodulator and decoder are tuned to work on these documents encoded the receiving fax machine produces the same document, in the shortest time and incur less cost. These devices are useful primarily for sending international documents otherwise it may be time to send the data if you use the previous analogue technology.

Thus, the current needs of business demand conceive of an advanced technology that can reduce the operating costs of the operation. This is feasible if the design integrates the characteristics of each technology in one unit. So the best idea is to buy a fax machine which is equipped with high quality printer with scanner and copier
