UNIX Shell Script Programming

When group of command is to be executed regularly, they should be stored in a file. This file is called Shell Script It is not mandatory to have .sh extension Vi editor is used to create shell script.  You can use any Unix based Operating System to run this script or you can also use UWIN (Unix like shell developed by Wipro)  program to execute Shell Script on Windows. Shell script is very sophisticated scripting language because white space also plays an important role in syntax grammar while in other languages like C and C++ or Java ignores white spaces.

For the practical purpose I am sharing this quick handy presentation which helps you to refreshing shell script syntax rules and various commands. I published this article to help students in MCA Unix Shell Script Programming. Download link is given at the end of this post. Also share this with all  GTU MCA students.

You can Download This Presentation From This Link.

1.  Create a package "sales" with following items:
• Create a class naming “Order” containing orderDate (type as java.util.Date), productName  (type as String) and quantity (type as int) as its member fields. SystemDate should be used as orderDate.
• Create a class naming “OrderManagment”, which manages instances of Order. This class must provide following methods :
• placeOrder: It should accept productName and quantity as its arguments, it should create a new Order instance using both arguments(productName and quantity) and adds it to TreeSet collection.
• displayOrdersByDate:Displays all the orders placed by current customer order by orderDate.
•  displayOrdersByName: Displays all the orders placed by current customer order by productName.
• storeOrder: It should accept Order instance as its arguments. It stores that Order instance to the file called ordersinfo.txt. (Use Comparable and Comparator interface).




2. Create an applet naming “timer”, which displays current time in middle of the applet screen in RED color once applet started. Provide a menu with two options: 
• StartTimer – if user presses StartTimer then timer should start and showing updated time after each minute in random color.
• StopTimer - if user presses StopTimer then timer should stop and display message to user that how many minutes/seconds have spent since user has started the timer.



3. Create a menu driven application naming drawShape using GUI, which has menu option like Line, Rectangle, Oval, etc…
• When user clicks on Line then ask user to enter line parameters using input dialog box and if parameters are proper then line should be drawn with BLUE color. Otherwise display proper error message.
• When user clicks on Rectangle then ask user to enter rectangle parameters using input dialog box and if parameters are proper then rectangle should be drawn with RED color. Otherwise display proper error message.
• When user clicks on Oval then ask user to enter oval parameters using input dialog box and if parameters are proper then oval should be drawn with GREEN color. Otherwise display proper error message.
• At a time only one shape should be displayed by frame.



4. Create a package “BankInfo” with following items
• Create a class naming “Account” with accountId (type as int), balance (type as double) and accountType (type as char), creationDate (type as java.util.Date) as its member fields.
• Create a class naming “Bank” class which manages a number of Account instances. Provide following methods 
• OpenAccount (Account acc) - adds acc instance to HashSet collection.
• CloseAccount (Account acc) – removes acc from collection.
• ListAccOrderByBalance () – which displays all account information order by balance.
• ListOrderByDate () - which displays all account information order by creationDate.
• Store (File flName) – which stores all accounts info to a file flName provided as parameter.  (Note : Use Comparable and Comparator iterfaces).
• Create a class naming “BankIntoTest” which tests above mentioned classes with main method.


5. Design a module called NewBookEntry for LibraryManagement system using GUI.
• This module manages information like bookId, category(MCA Sem -1, MCA Sem – 2, MBA Sem-3, ……..), title, author, edition, publication, IssueFlag (Y, N – Use checkbox).
• Make a NewBookEntry form which allows user to enter above mentioned information and provide menu option like Save, New, Search.
• Once user clicks Save option a unique bookId should be generated and all details along with bookId should be stored in a file called bookinfo.txt.
• Once user clicks New than all entered details should be cleared from NewBookEntry form.
• Once user clicks Search than whatever category user has selected, that category details should be searched in bookinfo.txt file created in option save, if details are available then display in TextArea field otherwise display proper message (eg. If user selects category MCA Sem-3 then searches this category details in file bookinfo.txt).


6. Create a package called “residence” with following items:
• Create a abstract class naming “Residency” which will be having an area (like 130 sq.yard, 180 sq.yard, etc..) and rate_peryard (like 20000, 18000, etc..) as its member fields and has following methods.
• Provide necessary constructor, getter and setter methods for this class.
• Provide one method called calculatePropertyPrice () which will return basic price (Hint : price = area * rate_peryard).
• Create a class naming “Flat” which is inherited from Residency and having its own instance field as maintenanceCharge. Override the calculatePropertyPrice () method which will return price of a flat with maintenaceCharge.
• Override necessary methods from Object class.
• Create a class naming “Villa”, which is inherited from Residency and having its own instance field as furnitureCharge.Override the calculatePropertyPrice () method which will return price of a Villa with furnitureCharge.
• Override necessary methods from Object class.
• Create a class naming “TestResidency” which tests above mentioned classes with main method. This class creates an array of Residency type and has following method.
• Int searchResidency (Residency res) – which searches a res instance in an array of Residency. If available then return index otherwise display proper message.
• double totalMaintenancePrice (Residency[] houses) - which returns total of all residency’s maintenanceCharge.
• Void DisplayOrderByPrice – which displays array of residencies order by their price (Note : Use Comparable and Comparator interfaces).


7. Create a multiThreading application.
• One thread will read char data from a file and print it to console (user has to create one file manually with char data separated by space).
• Second thread called asciiVal will display ASCII value of char data read by first thread to console.
• Use interThreadCommunication to generate following type of output.  (Assuming file has data like – T E C H N O L O G Y ……)
• Char value : T
• ASCII Value : 84
• Char Value : E
• ASCII Value : 69
• Char value : C
• ASCII Value : 67
• Char Value : H
• ASCII Value : 72


8. Create a GUI application which calculates charges for stay in Hotel, which allows user to enter duration as start date and end date as period while user wants to book a hotelRoom and to select a particular roomType (Regular, Delux, Cottage, Family, etc… use list). After selecting a particular roomChoice, display the calculated charges with start date and end date to user in dialogBox for confirmation. If user says ok then store these details to file else just close the dialogBox. Regular rates per day are as per following table. If user start date is between April to June or October to November, then room charges increased by 15%.

Java - Opening a URL in new window from an applet

This Applet example demonstrate how to open any URL in new browser page. The applet has Text Field  in which user  enters web URL and when user press Go button the specified URL will open in new browser window.

Create an applet which has a Text Field to accept a URL string, and displays the document of the URL string in a new browser window. When user enters http://www.google.com and clicks on Go button the applet will opens the url in new window and this is accomplished by getAppletContext.showDocument(url, target) method of the AppletContext.

Open_URL.Java
-----------------------------------------------------------------------------------------------

/* Applet program which takes URL from user into textfield and opens the url in new page */
/* Use applet in browser to get it run*/
import java.applet.*;
import java.awt.*;
import java.net.*;
import java.awt.event.*;

public class Open_URL extends Applet implements ActionListener
{
String link = "";
TextField tf;

public void init()
{
   
   Button b = new Button("Go");
   tf=new TextField("http://www.google.com");
 b.addActionListener(this);
 add(tf);
   add(b);
}

public void actionPerformed(ActionEvent ae)
{
   //get the link entered by user from textbox
  link= tf.getText();
        
   try
   {
    AppletContext a = getAppletContext();
    URL url = new URL(link);
    a.showDocument(url,"_blank"); // Opens the url in new window

         //a.showDocument(url,"_self");    _self to open url in same window  

   }
  
 catch (Exception e)
