In my code I have to tell the user how much of his salary he has to pay as tax

Question

but my code is not working. I have put double tax = 5/100*salary but it's only showing 0.0.

This is what I have tried.

package company;
import java.util.Scanner;
public class p6 {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Scanner sc=new Scanner(System.in);
        System.out.print("Enter your Salary(in lakhs): ");
        double salary=sc.nextDouble();
        if(salary<2.5)
        {
            System.out.println("You don't have to pay any tax.");
        }
        else if(salary>=2.5&&salary<5.0)
        {
            System.out.println("You have to pay 5% of your salary as tax.");
            double tax=5/100*salary;
            System.out.println(tax);
        }
        else if(salary >=5.0 && salary < 10.0)
        {
            System.out.println("You have to pay 20% of your salary as tax.");
            double tax=20/100*salary;
            System.out.println(tax);
    
        }
        else {
            System.out.println("You have to pay 30% of your salary as tax.");
            double tax=30/100*salary;
            System.out.println(tax);
        }
    }
}

OUTPUT:- Enter your Salary(in lakhs): 3 You have to pay 5% of your salary as tax. 0.0
