Assignment: Array Based GUI Assignment
Telephone call data has been collected from a company's telephone switch. You have been asked to analyze it and produce various statistics.
Input File
The input file is a sequential file. It is in no specific order. The file contains an extension number, type of call, and the length of call in seconds. A record is produced each time a call is made from that extension. You should create your own test file.
Field     Type     Description
Extension     Integer     Extension number. This is a 4 digit number. Valid Extensions are 2000 to 2020.
Type     Integer     Value of 1 means internal, any other value is an external call.
Time     Long     Length of call in seconds
Example:
�     2000,1,60 : ----->>>> Extension 2000 had an internal call that lasted 60 seconds
�     2000,1,356: ----->>>> Extension 2000 had an internal call that lasted 356 seconds
�     2019,2,65: ------>>>> Extension 2019 had an external call that lasted 65 seconds
�     2001,1,355: ----->>>> Extension 2001 had an internal call that lasted 355 seconds
Process
1.     Use 2 arrays to accumulate the time of calls for each extension, both internal and external.
2.     The reports and queries are to be produced from the arrays.
Hints:
�     Create 2 arrays: one for internal calls and one for external calls.
�     Load the arrays in Form Load: do not do any calculations here.
�     The report and queries can totally be produced from the arrays.
Output: Report
Telephone Useage Report
Extension Internal External
2000 4500 3500
2001 19350 22981
2002 2333 900
2003 3144 122
Totals 99999 99999
Output: Queries
On the form add add query capability.
1.     Average Total Utilization: Internal Calls: 9999 (total length of all internal calls / number extensions)
2.     Average Total Utilization: External Calls: 9999
3.     Extension with the highest internal call utilization: Ext xxxx; 9999 seconds.
4.     Extension with the highest total utilization.
Form Design
The design of the form is up to you. However, use the following guidelines:
�     use menus (preferred) or command buttons
�     use a common dialog box to ask for the file name
�     use a list box or text box to display the output
the caption on the form should include your name

Answer 1

hi
u can try like following code
if (menuName == "Print File")
          new mytextframe();
class mytextframe extends JFrame{
     JTextArea display = new JTextArea();
     public mytextframe()
          setSize(300,300);
          setVisible(true);
          add(display);
          display.setText( "ello");
}
