Show the algorithm for one week

This is how the requirement is, showing the calendar for a week.

public class Test {


public static void Main (string[] args) {
TODO auto-generated Method Stub


String number[] = new STRING[7];


Calendar calendar = Calendar.getinstance ();
Date date = new Date ();
SimpleDateFormat DateFormat = new SimpleDateFormat ("Yyyy-mm-dd");
String Currentday = Dateformat.format (date);


int currentdayofweek = Calendar.get (Calendar.day_of_week);

System.out.println ("Currentdayofweek =" +currentdayofweek);


Number[currentdayofweek-1] = currentday.substring (
Currentday.length ()-2, Currentday.length ());


int beforedaybetween=currentdayofweek-1;

int k=1;
int Y=1;

if (beforedaybetween>0) {

for (int i=beforedaybetween-1;i>=0;i--) {
