Practical No.:28Write a program to accept the elements of the classes

(i) Emp_no (ii) basic_pay (iii) Dept.T hese elements are passed through the applet using text field. T he salary slips along withcalculation of D.A., H.R.A., C.C.A and Gross Salary should be printed on the applet. T heD.A and C.C.A are calculated as

D.A. = 81% of basic salary if basic salary < 5000

= 51% of basic salary if basic salary is in the range 5000 to 7000

= 41% of basic salary if basic salary > 7000

C.C.A = 350/-

H.R.A. = 15% of basic salary

Code:import java.awt.*;import java.applet.*;

public class Salary extends Applet{T extField t1,t2,t3;

public void init(){t1=new T extField(8);t2=new T extField(8);

t3=new T extField(8);add(t1);add(t2);add(t3);t1.set T ext("0");t2.set T ext("0");t3.set T ext("0");}
