Below programs illustrate the adjustInto() method:
Program 1:




// Java program to demonstrate
// MonthDay.adjustInto() method
  
import java.time.*;
import java.time.temporal.*;
  
public class GFG {
    public static void main(String[] args)
    {
        // create a MonthDay object
        MonthDay mday = MonthDay.of(10, 31);
  
        // print instance
        System.out.println("MonthDay :"
                           + mday);
  
        // create a temporal object
        LocalDate date
 = LocalDate.parse("2007-12-03");
  
        // print instance
        System.out.println("LocalDate :"
                           + date);
  
        // apply adjustInto method of Year class
        LocalDate updatedlocal
 = (LocalDate)mday.adjustInto(date);
  
        // print instance
        System.out.println("LocalDate after"
                           + " applying adjustInto method: "
                           + updatedlocal);
    }
}
Output:
MonthDay :--10-31
LocalDate :2007-12-03
LocalDate after applying adjustInto method: 2007-10-31

Program 2:




// Java program to demonstrate
// MonthDay.adjustInto() method
  
import java.time.*;
import java.time.temporal.*;
  
public class GFG {
    public static void main(String[] args)
    {
        // create a MonthDay object
        MonthDay mday = MonthDay.of(12, 22);
  
        // print instance
        System.out.println("MonthDay :"
                           + mday);
  
        // create a temporal object
        LocalDate date
 = LocalDate.parse("2017-12-03");
  
        // print instance
        System.out.println("LocalDate :"
                           + date);
  
        // apply adjustInto method of Year class
        LocalDate updatedlocal 
= (LocalDate)mday.adjustInto(date);
  
        // print instance
        System.out.println("LocalDate after"
                           + " applying adjustInto method: "
                           + updatedlocal);
    }
}
Output:
MonthDay :--12-22
LocalDate :2017-12-03
LocalDate after applying adjustInto method: 2017-12-22
