Beginner Java if else range statement [duplicate]

I'm trying to find the total cost of delivery charge base on parcel weight.

Why when I put anything more than 2.5 it'll came out as 2 answers?

E.g:

Please enter parcelweight
3
The charge is 8.55
The charge is 7.3500000000000005

The corresponding code is:

    if(parcelweight  < 2.5)
   {
       System.out.println("The charge is" +parcelweight*3.5);      

   }
   else {

        if((parcelweight >=2.5 && parcelweight <=5));
        {
            System.out.println("The charge is" +parcelweight*2.85);
        }

        if(parcelweight > 5);
        { 
            System.out.println("The charge is" +parcelweight*2.45);
        }
   }
