    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
