import java.util.Scanner; 

public class demo { 
    public static double getCommissionRate(String productCode, double sale) throws Exception { 
    if(productCode.equals("ABC-A")) { 
     return sale * 0.05; 
    }else if(productCode.equals("ABC-B")) { 
     return sale * 0.1; 
    }else if(productCode.equals("ABC-C")) { 
     return sale * 0.12; 
    }else if(productCode.equals("ABC-D")) { 
     return sale * 0.15; 
    }else if(productCode.equals("ABC-E")) { 
     return sale * 0.17; 
    }else { 
     // You shouldn't be here 
     throw new Exception("Invalid Product Code"); 
    } 
    } 

    public static void main(String[] args) throws Exception { 
    Scanner z = new Scanner(System.in); 
    System.out.print("Enter Product Code: "); 
    String productCode = z.next(); 
    System.out.print("Enter value of sale: "); 
    // In reality you should never do currency calculations with doubles or floats 
    double sale = z.nextDouble(); 
    System.out.println("Commission: " + getCommissionRate(productCode, sale)); 
    } 
}
