Answer 1

用DATEFORMAT
import java.util.*;
import java.text.*;
public class test {
  public static void main(String[] args){
    GregorianCalendar gc=new GregorianCalendar();
    DateFormat df=DateFormat.getDateInstance(DateFormat.MEDIUM,Locale.CHINA);
    System.out.println(df.format(gc.getTime()));
    while(gc.get(GregorianCalendar.DAY_OF_WEEK)!=1){
      gc.add(GregorianCalendar.DATE,-1);
    }
    System.out.println(df.format(gc.getTime()));
  }
}

Answer 2

用SimpleDateFormat
import java.util.*;
import java.text.*;
public class test {
  public static void main(String[] args){
    GregorianCalendar gc=new GregorianCalendar();
   SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd");
    System.out.println(sdf.format(gc.getTime()));
    while(gc.get(GregorianCalendar.DAY_OF_WEEK)!=1){
      gc.add(GregorianCalendar.DATE,-1);
    }
    System.out.println(sdf.format(gc.getTime()));
  }
}

SimpleDateFormat sf=new SimpleDateFormat("yyyy-MM-dd");
