Chapter - 9 Introduction to Word Processing

Summary

Early word processors used tag-based markup for document formatting. When a specific portion of the content needs some special effect, a particular tag is put on both the sides of the text.

11. Write a Java program to input basic salary of an employee and calculate its Gross salary according to following:

11. Write a Java program to input basic salary of an employee and calculate its Gross salary according to following: Basic Salary <= 10000 : HRA = 20%, DA = 80% Basic Salary <= 20000 : HRA = 25%, DA = 90% Basic Salary > 20000 : HRA = 30%, DA = 95% Static Solution :- class salary { public static void main(String args[]) { double basic=20000.50,gross,da,hra; if(basic <=10000) { da = basic * 0.8; hra = basic *0.2; } else if(basic <=20000) { da = basic * 0.9; hra = basic *0.25; } else { da = basic * 0.95; hra = basic * 0.3; } gross = basic + da + hra; System.out.println("The Gross Salary is :-"+gross); } } Output :- Dynamic Solution :- class salary { public static void main(String args[]) { double basic=20000.50,gross,da,hra; Scanner in = new Scanner(System.in); System.out.println("Enter the Basic Salary
