Integer Too Large Error
Hey experts :)
I'm writing a program (my second on methods) that is supposed to convert military time to "normal" time. I think I have it figured out, expect that in my method, I have the following syntaxJava Code:if (hour == 00) { return "12"; }
Also, just in case, here is my full code....if you see any other errors, I'd appreciate a heads up! :)
~Jaime
Java Code:public class TimeConvert { public static void main(String[] args) { Scanner in = new Scanner(System.in); System.out.print("Please enter the time: "); int milTime = in.nextInt(); } /** A method to extract the minutes portion of an integer representing Military time. @param milTime, the military time provided: hhmm @return a string of the form 9:35 am or 7 pm */ public static String militaryToOrdinaryTime(int milTime) { //your work here int minutes = milTime % 100; int hour = milTime / 100; if (hour >= 12) { System.out.println(hour + ":" + minutes + "pm"); } else { System.out.pringln(hour + ":" + minutes + "am"); //convert hours if (hour == 00) { return "12"; } if (hour == 01) { return "1"; } if (hour == 02) { return "2"; } if (hour == 03) { return "3"; } if (hour == 04) { return "4"; } if (hour == 05) { return "5"; } if (hour == 06) { return "6"; } if (hour == 07) { return "7"; } if (hour == 08) { return "8"; } if (hour == 09) { return "9"; } if (hour == 10) { return "10"; } if (hour == 11) { return "11"; } if (hour == 12) { return "12"; } if (hour == 13) { return "1"; } if (hour == 14) { return "2"; } if (hour == 15) { return "3"; } if (hour == 16) { return "4"; } if (hour == 17) { return "5"; } if (hour == 18) { return "6"; } if (hour == 19) { return "7"; } if (hour == 20) { return "8"; } if (hour == 21) { return "9"; } if (hour == 22) { return "10"; } if (hour == 23) { return "11"; } return ""; } } }

Re: Integer Too Large Error
I think I may have figured it out. I took off the "0" for each of the 1 digit hours and the error went away. Makes sense since a calculator won't show "08" it will only show "8". My new fun problem is that I"m getting errors on my "Scanner in = new Scanner(System.in)" line. Does it have something to do with where it's located? The "Scope" issue I just read about?

Re: Integer Too Large Error
Found the answer to this one too.....
Last one, I hope....I'm now getting this error: TimeConvert.java:57: error: missing return statement
Is it because I have return ""; ? And if so, what should it be? My book has that as the example for a similar exercise.

What's "pringln"?

Re: Integer Too Large Error
Yah, typo. Should have been println.
Below is my most current code. I'm now getting errors on the quote marks in each of the "if" statements. I'm thinking it's because they may be for strings, and I'm trying to return an integer? However, I'm not sure how to fix it.
Java Code:import java.util.Scanner; public class TimeConvert { public static void main(String[] args) { Scanner in = new Scanner(System.in); System.out.print("Please enter the time: "); int milTime = in.nextInt(); } /** A method to extract the minutes portion of an integer representing Military time. @param milTime, the military time provided: hhmm @return a string of the form 9:35 am or 7 pm */ public static String militaryToOrdinaryTime(int milTime) { //your work here String time = ""; int minutes = milTime % 100; int hour = milTime / 100; if (hour >= 12) { time = hour + ":" + minutes + "pm"; } else { time = hour + ":" + minutes + "am"; } return time; } /** Converts hours */ public static int milHours(int hour) { //convert hours if (hour == 0) { return "12"; } if (hour == 1) { return "1"; } if (hour == 2) { return "2"; } if (hour == 3) { return "3"; } if (hour == 4) { return "4"; } if (hour == 5) { return "5"; } if (hour == 6) { return "6"; } if (hour == 7) { return "7"; } if (hour == 8) { return "8"; } if (hour == 9) { return "9"; } if (hour == 10) { return "10"; } if (hour == 11) { return "11"; } if (hour == 12) { return "12"; } if (hour == 13) { return "1"; } if (hour == 14) { return "2"; } if (hour == 15) { return "3"; } if (hour == 16) { return "4"; } if (hour == 17) { return "5"; } if (hour == 18) { return "6"; } if (hour == 19) { return "7"; } if (hour == 20) { return "8"; } if (hour == 21) { return "9"; } if (hour == 22) { return "10"; } if (hour == 23) { return "11"; } return ""; } }

Re: Integer Too Large Error
Your method 'milHours' says it's returning an int.
So why are you returning Strings?Please do not ask for code as refusal often offends.

Re: Integer Too Large Error
I assumed I had to use strings because of the colon and the pm/am....when I made my TIME variable an int, I got a whole other set of errors....

Re: Integer Too Large Error
You have to return the type you have declared your method as returning.
So start there.
If you feel you need a String then change the return parameter to a String instead of an int, but what it should be is entirely down to your requirements.
Then again, you're not even using the method...Please do not ask for code as refusal often offends.
