Constructors

[zhider]

Hey guys, so on this project we are supposed to use constructor methods to print the date, right now I am getting the error that it cannot find the variable MoreDates on the code: printDate (MoreDates t); in the main method. Any ideas?

public class MoreDates {
int year, month, day;
    /**
     * @param args the command line arguments
     */
public MoreDates () {
      this.year= 0;
      this.month=0;
      this.day=0;  
}
public MoreDates(int year, int month, int hour){
    this.year=year;
    this.month=month;
    this.day= day;
    }
public static void printDate (MoreDates t){
     MoreDates t1= new  MoreDates (2012, 11, 9);   
     System.out.println (t.month + ", " + t.day + ", "+ t.year);
}
public static void main(String[] args) {
     printDate (MoreDates t);    
    }
}

You have mixed up the way methods are declared and how they are called. Your error is on line 21, where you have use the method declaration notation while you should have used a method call. The method printDate expects an instance of MoreDates (like you did on line 17, but that is the wrong place), so you have to create one first and use that as parameter.

So how would I change this code to make it work?

Read the tutorial that SurfMan links to to learn how to both declare and use methods, and then use this information to try to fix your code. If still stuck after this, show us your latest attempt.

... we are supposed to use constructor methods ...

Just to set the terminology straight: constructors are constructors, methods are methods. In Java, there's no such thing as a constructor method.

if you want to call a static method, the form is like this: ClassName.MethodName.
regardless your logic, if you want to run your code, you should call the static method like what i said before, and your static method should take no argument. and in the method body, it should be "t1" instead of "t".
to be honest, you really should go to learn the basic concept of method and constructor.
have a nice programming day.
