1. Write a Java program to calculate the electricity bill for the given
   unit.
   import java.util.Scanner;
   public class ElectricBill
   {
   public static void main(String args[])
   {
   Scanner sc = new Scanner(System.in);
   System.out.print("Enter Unit:");
   int unit=sc.nextInt();
   double bill=calculateElectricBill(unit);
   System.out.println("Bill Amount="+bill);

}
public static double calculateElectricBill(int unit)
{
double fixed_price=100;
double rate0_100=6.30;
double rate101_200=6.85;
double ratemorethan200=7.40;
if(unit<=100)
{
return fixed_price+(unitrate0_100);
}
else if(unit<=200)
{
return (fixed_price+(100rate0_100)+(unit-100)rate101_200);
}
else
{
return (fixed_price+(100rate0_100)+(100*rate101_200)+(unit-
200)*ratemorethan200);
