using java 8 fluent Date/Time classes:

LocalDate inputDate = ...
LocalDate prevSat = inputDate.with(TemporalAdjusters.previous(DayOfWeek.SATURDAY));

@seethalakshmi, check the documantation for LocalDate to manipulate the date in the past, present or future. https://docs.oracle.com/javase/8/docs/api/java/time/LocalDate.html – Tom Jul 25 '16 at 13:06

Try this:

Calendar cal=Calendar.getInstance();
cal.add( Calendar.DAY_OF_WEEK, - cal.get(Calendar.DAY_OF_WEEK)); 
System.out.println(cal.get(Calendar.DATE));

Here. 2 working solutions. I'm first calculating how much days passed till last Saturday and then I'm making new date in which i deduct number which i get from method. That is giving us exact date of last saturday. Second solution is simpler, its using Java 8 features.

import java.time.DayOfWeek;
import java.time.LocalDate;
import java.time.temporal.TemporalAdjuster;
import java.time.temporal.TemporalAdjusters;
import java.util.Calendar;
import java.util.Date;
import java.util.Locale;

public class CalendarSat {

    public static void main(String[] args) {
        Date date = new Date();
        date.setDate(date.getDate()-lastSut(date.getDay()));
        System.out.println("Custom solution with method: " + date);

        LocalDate inputDate = LocalDate.now();
        LocalDate prevSat = inputDate.with(TemporalAdjusters.previous(DayOfWeek.SATURDAY));
        System.out.println("Java 8 solution: " + prevSat);

    }

    public static int lastSut(int currentDay) {
        int toRet = 0;
        int num = 6;
        for(int i = 0; i<7;i++) {
            if(num==currentDay) {
                toRet=i;
            }
            if(currentDay==0)
                currentDay=7;
            currentDay--;       
        }       
        return toRet;
    }
}
