        Scanner fetch = new Scanner(System.in);
        double area, propCost;
        System.out.print("Porperty cost: ");
        area = fetch.nextInt();
        calcTotalCharge();
        
        
    }
    
    
    public double calcTotalCharges(double area){
    double actualArea = area * RATE;
    double propertyCharge = actualArea * UNITPRICE;
    double propertyCost = propertyCharge + propertyCharge * GST;
    System.out.print(propertyCost);
        return propertyCost;
    }
    
}

Answer 1

In main method call calcTotalCharge() method with parameter and return type of  calcTotalCharge() assign to a variable and better to use static keyword in function defination or you can create an object for that class and with that help you can call that function.
