java程序接受任何格式的日期作为输入并打印月份,

Question

java程序接受任何格式的日期作为输入并打印月份,

可能吗

我尝试了以下,任何其他替代方式/想法？

import java.text.*;

import java.util.*;


public class PrintMonth3{


    public static void main(String args[])throws Exception{

    String patterns[]={"dd.MM.yyyy","dd.MM.yy","dd.MMM.yyyy","dd.MMM.yy","d.MM.yyyy"};

    String input="4.06.2011";

    for(int i=0;i<patterns.length;i++)
        doPrintMonth(patterns[i],input);

    System.out.println("\nNot a valid date format..");


    }



    public  static void doPrintMonth( String pattern,String input ) {


    try{
    SimpleDateFormat sdf=new SimpleDateFormat(pattern);

    Date output=sdf.parse(input);


    String mon[]={"Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"};
    int m=output.getMonth();
    System.out.println("\n\t" + mon[m] );
    System.exit(0);
    }
    catch(Exception e){}    


    }


}

不,这不对.如何区分01/02/2011(日/月/日)和01/02/2011(MM /日/年)？
