Hello,
I have a program called Date. While this program compiles and runs, I have noticed something weird. I have an output line that displays my values twice.
Sample Run:
The word date output is: February 12 2009
The numeric output of the date is: 2/12/2009
The next incremented date is: 2/12/2009
The next incremented date is: 2/13/2009
Why is that? I have the same issue in my other program. There is something i am overlooking on the consistent basis
Any help will be appreciated:
Code:
// Main
import java.io.*;
public class Main {
/**
* @param args the command line arguments
*/
public static void main(String[] args)throws IOException
{
BufferedReader stdin = new BufferedReader (new InputStreamReader(System.in)); // Calling on java class which allow to read user input
// Local Variables
String temp;
int month;
int day;
int year;
Date myDate = new Date();
// Reading user input for month
System.out.println("Please enter month in numeric format 1-12:");
temp = stdin.readLine();
month = Integer.parseInt(temp); // Converting a string into int
// Reading user input for day of the month
System.out.println("Please enter day of the month in numeric format 1-31:");
temp = stdin.readLine();
day = Integer.parseInt(temp); // Converting a string into int
// Reading user input for the year
System.out.println("Please enter year:");
temp = stdin.readLine();
year = Integer.parseInt(temp); // Converting a string into int
// Calling methods from a class Date
myDate.outputDate(month,day,year);
myDate.increment(month,day,year);
}
}// Class Date
