Same can be achieved a bit more easily by just [icode]Double.parseDouble(args[0])[/icode] Is the valueOf method called during autoboxing ? 14 Years Ago by daudiam Is it true that during autoboxing, the type.valueOf() method is called (which creates a new object only if another with the same primitive constant is not in the intern list. This applies to cases where interning is allowed. Otherwise, it creates a new object using new() ). Is this right ? Re: Java- Payroll program help with String.valueOf() 13 Years Ago by Ezzaral Take another look at the calls in those error messages. Does your ProdArray have a getFee() method? Re: Java- Payroll program help with String.valueOf() 13 Years Ago by CB8379 It does have a getFee method .. (I think).. it is in the subclass (line 189). Or am I incorrect? Re: Java- Payroll program help with String.valueOf() 13 Years Ago by Ezzaral ProdArray is just an array. Re: Java- Payroll program help with String.valueOf() 13 Years Ago by CB8379 the ProdArray[] is meant to hold objects (I actually had 20 points knocked off on Sunday because I was not using objects in my code, so I tried to update it). I still have not had one successful build since my first project. Re: Java- Payroll program help with String.valueOf() 13 Years Ago by Ezzaral There is a difference between calling a method on an array and calling a method on an [I]element[/I] of the array. Re: Java- Payroll program help with String.valueOf() 13 Years Ago by CB8379 All right, I think that I am officially confused now. I had gone back to re-read our text. From what I can tell, either the elements can be passed to a method for modification or the array value could be passed to the method to modify. With the program I am trying to build, the array element needs to be passed to the method because each element … Re: Java- Payroll program help with String.valueOf() 13 Years Ago by Ezzaral The important difference here is that ProdArray is an array reference. ProdArray[0] is an element of that array. It is those elements that you wish to call methods on. Look at line 89 in the code you posted above. See the difference in syntax? Re: Java- Payroll program help with String.valueOf() 13 Years Ago by CB8379 ok.. I think I know what you are saying. So instead of having getProductNumber(), I should have getProductNumber[i].. Or am I still completely wrong? Re: Java- Payroll program help with String.valueOf() 13 Years Ago by Ezzaral You specify the index of the element on the array itself. As I said, look at lines 89,90,91... in your code above. On those lines, you are calling methods on a particular element in the ProdArray array. ProdArray[0] is the first element in ProdArray. It is an object of type 'Product4'. ProdArray[1] is the second element in ProdArray. Re: Java- Payroll program help with String.valueOf() 13 Years Ago by CB8379 I tried to change the method calls for output to getProductNumber(i); (i is for the count in the array as it passes though each item element) and now I am receiving the error: cannot be applied to given types. Re: Java- Payroll program help with String.valueOf() 13 Years Ago by Ezzaral Ok, third time: look at line 89. Do you see anything that looks like getProductNumber(i)? Re: Java- Payroll program help with String.valueOf() 13 Years Ago by CB8379 all right- on line 89 I have ProdArray[i].getProductNumber(). The ProdArray[i] is meant to retrieve the element stored in the given loop for [i], weather it be element [0] through [4] and for each pass through the array of elements, display what is in the array. You asked if I see anything that looks like getProductNumber(i) and that would be what … Re: Java- Payroll program help with String.valueOf() 13 Years Ago by Ezzaral You have already gotten the object. It is ProdArray[i]. You call methods on it just the same as you would any Product4 object. You don't specify any indexes in the method call parenthesis. Re: String methods - valueOf 15 Years Ago by JamesCherrill I'm curious. Why return a String rather than the boolean? Re: String methods - valueOf 15 Years Ago by JamesCherrill If all you want to do is to print the boolean there's no need to convert to String - print does that for you. You can just use System.out.print("My boolean is " + myBooleanVariable); Re: String methods - valueOf 15 Years Ago by anevins [QUOTE=JamesCherrill;1110122]I'm curious. Why return a String rather than the boolean?[/QUOTE] Sorry about not replyin earlier, the requirement is to return a specific sentence, rather than just 'true' or 'false' Re: String methods - valueOf 15 Years Ago by JamesCherrill If you need a sentence, I'd go with String sentence = (myBooleanVar) ? "Sentence 1": "Sentence 2"; (like in post #2) Re: String methods - valueOf 15 Years Ago by thekashyap [QUOTE=anevins;1110092]On your 4th line of code, that gives my IDE an error of incompatible types, required : boolean, found : java.lang.String[/QUOTE] First: It's this OR that. Use the one that works. Second: I tested the code before posting. Checked again, it compiles fine with 1.5 & 1.6. Unless you changed the type of "suffix"…
