Command line Input string in Java program

I am getting compilation error when I try the attached code:
mainDate.java:31: <identifier> expected
cal.setTime( date ) ;
           ^
mainDate.java:31: <identifier> expected
cal.setTime( date ) ;
                 ^
2 errors

Also how to I put the user input (say "December 30, 1998") onto a String variable (say "myStr2")? My above code is not working well (when I run the program, after typing in the code and hitting enter, it does not exit the program until I hit control-C.)

import java.util.*; 
String myStr2 = "December 30, 1998";
 
SimpleDateFormat format = new SimpleDateFormat( "MMMMM dd, yyyy" ) ;
Date date = format.parse( myStr2 ) ;
Calendar cal = Calendar.getInstance() ;
cal.setTime( date ) ;
 
int dd = cal.get( Calendar.DATE ) ;
int mm = cal.get( Calendar.MONTH );
int yy = cal.get( Calendar.YEAR ) ;

To compile this code the code must be within the main method like you originally had.  That is why it wont compile.


If you are just running the main method of a class, then the program will terminate after the completion of the method, otherwise you can use System.exit(0); to end a program.

public static void main(String[] args)
{
 
String myStr2 = "December 30, 1998";
 
SimpleDateFormat format = new SimpleDateFormat( "MMMMM dd, yyyy" ) ;
Date date = format.parse( myStr2 ) ;
Calendar cal = Calendar.getInstance() ;
cal.setTime(date) ;
 
int dd = cal.get( Calendar.DATE ) ;
int mm = cal.get( Calendar.MONTH );
int yy = cal.get( Calendar.YEAR ) ;
}

Here is my complete code. It has main.
I still get 10 error:

you have to import SimpleDateFormat and handle ParseException!

try this code,

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;


public class mainDate2{
      
      public static void main( String args[] ){
            String myStr2 = "December 30, 1998";
            
            try{
                  SimpleDateFormat format = new SimpleDateFormat( "MMMMM dd, yyyy" );
                  Date date = format.parse( myStr2 );
                  Calendar cal = Calendar.getInstance();
                  cal.setTime( date );
                  
                  int dd = cal.get( Calendar.DATE );
                  int mm = cal.get( Calendar.MONTH );
                  int yy = cal.get( Calendar.YEAR );
            }catch( ParseException e ){
                  e.printStackTrace();
            }
      }
}
