Practical 1 Create a Java Desktop application to find the largest number among the three floating-point numbers. The following is the screen used to find largest number among three number: Practical 2 Create a Java Desktop Application to enter your friends rollno, name, address, section and grade. Using a JButton 's click event handler, display the details of inputs into a JTextArea control. Note that the JTextArea background would be in yellow color. Practical 3 Create a Java Desktop Application to fmd sajary of the employee on the basis of"designation" selected using JComboBox. The JComboBox contains the following designations with respective sajaries:

5 Designation Project Manager Manager Architect Team Leader Sr.Program mer Salary Practical 4 Create a Java Desktop application to do mathematical operations like addition, subtraction, multiplication, division and modulus of two numbers and display the result with appropriate text box after clicking a JButton control. Practical 5 Write a program to input any number and print them in reverse order using while statement. Whereas the input number must be positive. The following is the screen used to print the reverse of a number :

6 Practical 6 Mr. Vidyarthi works in Blossoms Public School as a programmer. He is required to develop a student record. The school offers two different streams, medical and non-medical, with different grading criteria. The school also offers incentive to the NCC cadets in the form of a 3% increment in percentage for all the NCC cadets. The grading criteria for the two streams is given below : Stream Percentage Grade Medical >=80 A I 79 B <60 c Non-Medical >=75 A 74 B c <50 - (a) Write the commands to disable the textboxes txtpercentage and txtgrade. Also, set Medical as default stream. (b) Write the code for cmdclacper to calculate the percentage after fmding the total marks of first term and second term (assuming that both marks are out of 100). Also ensure that NCC cadets get an increment of 3% in their percentages. (c) Write the code for cmdcalcgrade to calculate the grade depending on the stream selected according to the criteria given above. (d) Write the code for cmdclear Command Button to clear all the text boxes and the check box and Medical as default stream.

7 Practical 7 Define a class Report with the following specification : Data members adno Integer name String marks 5 floating point values average average marks obtained getavg() to compute the average obtained in five subjects Member methods read_info() function to accept values for adno, name, marks, and invoke the function getavg(). displayinfo() function to display all data members on thescreen you should give function definitions. Cakculate the average mark and print a message "You are Passed" if percentage is greater than 40, otherwise print "You are Failed". Also, at runtime, the colour of"you are Passed" must be Blue and "You are Failed"must be Red with font size 10. Practical 8 Create an application to design a fonn containing ListBox and ComboBox. Add major cities to both ListBox and ComboBox through a TextBox. Also provide three command buttons for clearing thetextbox. ListBox and ComboBox. When you click on a button (JButton), the action will affect to respective controls.also, use command buttons for clearing the TextBox, ListBox and ComboBox. See the form given below:

8 Practical 9 Read the following case study and answer the questions that follows : Sagar electronics has the following products with their list prices given. The store gives a 10% discount on every product. However, at the time of festival seasons, the store gives a further 7% festival discount after 10%. Product Name List Price Discount Price Washing Machine Color Television Refrigerator OTG N ote that the Product Name is stored in JComboBox control. Practical 10 HDFC Bank frequently needs to calculate the interest and amount due for his clients. He asks his software programmer to design an interest calculator which wiji calculate the compound interest and amount due. The bank offers two different accounts fixed deposit IUld recurring deposit with different

9 (a) Write the code to disable the text boxes txtlnterest, txtamount, txtrate and txtdate in the form when the form activated. (b) Write the code for cmdclear command button to clear allthe textboxes and check box except txtdate. Set the default choice in the option button as Fixed Deposit. (c) Write the code for the click event of the command button cmdcalculate to calculate compound interest and amount and display the values in textboxes txtlnterest and txtamound depending on the principal, rate and time Note that the compound interest is calculated as P*(l+r/100) "T& amount as Principal+ Interest. Rate is calculated based on the time according to the following table. Account Time(in years) Rate Fixed Deposit <=1 10% > 1and<=5 12% >5 15% Recurring Deposit <=2 10% >2and<=7 12% >7 15% - An additional rate of 2% is given to senior citizens i.e. if the chksr checkbox is checked. {(/) Write the code for cmdexit to exist the application. Practical 12 Create a Java Desktop Application to perform the following calculations: (a) calculation of Total and Average Marks as : total = english + maths + science +history average= total/4

10 (b) Displaying the Distinction/Average Marks based on the Total Marks scored. {c) Display.ing the grade (A, B, C, D, F) based on the Average Marks Scored. Average Result Grade >=75 Distinction A >=60 First Class B >=50 Second c >=40 Class D Otherwise Average F Fail Practical 13 Create a Java Desktop Application to find the Incentive(%) of Sales for a Sales Person on the basis of following feedbacks: Feedback Incentive (%) Maximum Sales 10 Excellent Customer 8 5 Feedback Maximum Note that the sales entry should not have space. Calculate the tota l incentive a<; :Sales amount* incentive

11 Practical 14 Develop a Desktop Application to test all String manipulation methods using a JButton click event procedure. Note that the result of String manipulation methods will be placed in a JTextArea control. Note. The operations will be implemented using two strings as: your name and school.
