1 15 Create a Java GUI application which has the following interface as shown below: When the Cal Discount button is clicked, it should display the Bill Amount & the Discount in the respective text fields. The Bill Amount can be calculated as (Quantity * Rate). The Discount should be calculated as per the mode of payment selected by the user. Mode of Payment Discount Gold 20% of Bill Amount Silver 15% of Bill Amount Platinum 10% of Bill Amount When the Cal Net Amount button is clicked, it should display the Additional Discount & the Net Amount in the respective fields. An additional discount of 5% should be given on the Bill Amount if it is greater than 25,000. The Net Amount should be calculated as (Bill Amount Discount Additional Discount). Code for Cal Discount Button: int qty = Integer.parseInt(jTextField2.getText()); float rate = Float.parseFloat(jTextField3.getText()); float BAmt= qty * rate; float disc=0; jtextfield4.settext("" + BAmt); if(goldrb.isselected()) disc = 0.20f *BAmt; else if (SilverRB.isSelected()) disc = 0.15f * BAmt; else disc = 0.10f * BAmt; jtextfield5.settext("" + disc); jbutton2.setenabled(true);

2 Code for Cal Net Amount Button: float BAmt = Float.parseFloat(jTextField4.getText()); float disc = Float.parseFloat(jTextField5.getText()); float AddDisc = 0; if(bamt > 25000) AddDisc = 0.05f * BAmt; jtextfield6.settext("" + AddDisc); float NetAmt = BAmt - disc - AddDisc ; jtextfield7.settext("" + NetAmt); Code for Reset Button: private void jbutton3actionperformed(java.awt.event.actionevent evt) { jtextfield1.settext(null); jtextfield2.settext(null); jtextfield3.settext(null); jtextfield4.settext(null); jtextfield5.settext(null); jtextfield6.settext(null); jtextfield7.settext(null); buttongroup1.clearselection(); 16 Create a Java GUI application which has the following interface as shown below: The Entry Fees is Rs.500 per person and rides of water park will cost Rs.250 extra per person. When the Calculate button is clicked, it should display the Entry Fees as: (Entry Fees per person * No. of People). If the Water Park check box is selected, the text field for Water Park Charges should display (Water park charges per person * No. of People). And the Total Amount text field should display the sum of Entry Fees & Water Park Charges.

3 Code for Calculate Button: int nop = Integer.parseInt(jTextField1.getText()); double ef= 500 * nop, wpc=0; if(jcheckbox1.isselected()) wpc= 250 * nop; jtextfield2.settext(""+ef); jtextfield3.settext(""+wpc); jtextfield4.settext(""+(ef+wpc)); Code for Clear Button: jtextfield1.settext(null); jtextfield2.settext(null); jtextfield3.settext(null); jtextfield4.settext(null); jcheckbox1.setselected(false); Code for Exit Button: private void jbutton3actionperformed(java.awt.event.actionevent evt) { System.exit(0); 17 Create a Java GUI application which has the following interface as shown below:

4 When the Calculate Wages button is clicked, it should display the Total Wages in the respective text filed as per the following criteria: Male and female labourers are paid at the rate of Rs.140/- & Rs. 160/- per day respectively. Skilled labourers are paid an extra amount of Rs. 50 per day. Code for Calculate Wages Button: int nod = Integer.parseInt(jTextField2.getText()); int tw = 0; if(jradiobutton1.isselected()) tw = 140 * nod; else if(jradiobutton2.isselected()) tw = 160 * nod; if (jcheckbox1.isselected()) tw += 50 * nod; jtextfield3.settext("" + tw); Code for Clear Button: jtextfield1.settext(null); jtextfield2.settext(null); jtextfield3.settext(null); buttongroup1.clearselection(); jcheckbox1.setselected(false); Code for Exit Button: private void jbutton3actionperformed(java.awt.event.actionevent evt) { System.exit(0);

5 18 Create a Java GUI application which has the following interface as shown below: The application accepts payments in 3-modes:- Cheque, Cash & Credit cards. The discount given as per mode of payment is as follows: Mode of Payment Discount Cash 8% Cheque 7% Credit Card Nil If the Bill Amount is greater than 15,000 then the customer gets an additional discount of 10% on Bill Amount. When the Calculate Discount button is clicked, the Total Discount should be calculated as per the given criteria and should be displayed in the respective text filed. Also, the Calculate Net Amount button should be enabled. When the Calculate Net Amount button is clicked, the net amount should be calculated & displayed in the respective text field. Code for Calculate Discount Button: double bamt= Double.parseDouble(jTextField2.getText()); double disc; String mop = (String) jcombobox1.getselecteditem(); if (mop.equals("cash")) disc = 0.08 * bamt; else if (mop.equals("cheque")) disc = 0.07 * bamt; else disc = 0; if (bamt > 15000) disc += 0.10 * bamt; jtextfield3.settext("" + disc); jbutton2.setenabled(true);

6 19 Code for Calculate Net Amount Button: double bamt= Double.parseDouble(jTextField2.getText()); double disc= Double.parseDouble(jTextField3.getText()); double namt = bamt - disc; jtextfield4.settext("" + namt); Each activity consists of 10 marks Code for Calculate Total Score Button: int points =0; if(jcheckbox1.isselected()) points +=10; if(jcheckbox2.isselected()) points +=10; if(jcheckbox3.isselected()) points +=10; jtextfield6.settext(""+ points);
