How to Create a GUI application Showing Details in I-Card Format, NetBeans: Java Programming

NetBeans provides a simple and easy way to create a new project and input some information in sql programming. The article will let the programmer do the same thing.
  • Start NetBeans and create a new project and add four labels and four textfields from the palette tab as explained in earlier article.

  • Set following font properties for all the labels and textfields.
    Type: Comic Sans MS (you may choose any other font if you wish)

  • Adjust the placement of Heading, whose properties you set just now, by dragging it, so that it appears in the middle horizontally. Set name property of the labels respectively:
    jLabel1   to    titlelabel1
    jLabel2   to    firstNameLabel
    jLabel3   to    lastNameLabel
    jLabel4    to   classLabel
    jTextField1    to        firstNameTextField
    jTextField2    to        lastNameTextField
    jTextField3    to        classTextField
    jTextField4    to        sectionTextField

  • Set text property for these labels as given below:
    titleLabel1  to  Title(Mr/Ms)
    firstnameLabel  to  First Name
    lastnameLabel    to    Last Name
    classLabel  to  Class

  • Also set the text property of each of null string i.e. “ “ and resize them as per the screenshot. Now your frame should look like the one shown in below

  • Add a Button control by dragging it from Palette to frame. Name it as okButton. Set its text property to Generate and its font remain as is.
Before you add text area to frame, you may need to increase the size of the frame. For this drag the boundary of the frame in desired direction to get its desired size.
  • Just as you added other controls, add a text field control to your frame and give it a size according to I-Card. Name it as repTextArea. To name the text area field, you need to click the jScroolPane control in inspector window. A Scroll pane automatically gets added to your frame when you add a text area.

  • Adding Functionality to Frame
    Now double click on the boundary of the push button i.e., the okButton in design space. The code editor window will get opened. In it, without touching the cursor, simply type the following code. For now you won’t understand it. But it will be clear to you later when we’ll be talking about java concepts.
When you use getText() with a control’s name followed by a dot(.). It returns the text stored in the control. So the code will give the text stored in the control whose name is titlenameField.

Now save your work by pressing Ctrl + S and press F6 to run your project. You may also click Run icon on the toolbar. See your application run. After entering details in text fields, click on Generate. Wow, isn’t it similar to one shown in screenshot?

difference between structure and union in C Language

In c language article we will see the difference between union and structure. Both are the user define datatype in c language. See the table which is mentioned below: ASP.NET Video Tutorial Series Structure Union1.The keywordstruct is used to define a structure 1. The keyword union is used to define a union. 2. When a variable is associated with a structure, the compiler allocates the memory for each member. The size of structure is greater than or equal to the sum ofsizes of its members. The smaller members may end with unused slack bytes. 2. When a variable is associated with a union, thecompiler allocates thememory by considering the size of the largest memory. So, size of union is equal to the size of largest member. 3. Each member within a structure is assigned unique storage area of location. 3. Memory allocated is shared by individual members of union. 4. The address of each member will be in ascending order This indicates that memory for each member will start at different offset v…

Difference between Linear search and Binary Search in c language

SQL Video Channel : Download all SQL Video

Binary Search Linear Search Works only on sorted items. such as  1,2,3,4,5,6  etc
Works on sorted as well as unsorted items. 12,4,5,3,2,1 etc Very efficient if the items are sorted Very efficient if the items are less and present in the beginning of the list. such as Suppose your list items are : 12,3,4,5,1 and you want to search 12 number then you get beginning in the list. Works well with arrays and not on linked lists. Works with arrays and linked lists.
Number of comparisons are less More number of comparisons are required if the items are present in the later part of the array or its elements are more.

Memory representation of Linked List Data Structures in C Language

Memory representation of Linked List

             In memory the linked list is stored in scattered cells (locations).The memory for each node is allocated dynamically means as and when required. So the Linked List can increase as per the user wish and the size is not fixed, it can vary.

               Suppose first node of linked list is allocated with an address 1008. Its graphical representation looks like the figure shown below:

      Suppose next node is allocated at an address 506, so the list becomes,

  Suppose next node is allocated with an address with an address 10,s the list become,

The other way to represent the linked list is as shown below:

 In the above representation the data stored in the linked list is “INDIA”, the information part of each node contains one character. The external pointer root points to first node’s address 1005. The link part of the node containing information I contains 1007, the address of next node. The last node …
