下面的程序说明了 TemporalAdjusters.next() 方法：
方案一：

// Java program to demonstrate
// TemporalAdjusters.next()
  
import java.time.*;
import java.time.temporal.*;
  
public class GFG {
    public static void main(String[] args)
    {
  
        // get TemporalAdjuster with
        // the next in month adjuster
        TemporalAdjuster temporalAdjuster
            = TemporalAdjusters.next(
                DayOfWeek.WEDNESDAY);
  
        // using adjuster for local date time
        LocalDate localDate
            = LocalDate.of(1998, 10, 31);
        LocalDate nextDOW
            = localDate.with(temporalAdjuster);
  
        // print
        System.out.println(
            "next day of the week having"
            + " WEDNESDAY for localdate "
            + localDate + " is: "
            + nextDOW);
    }
}

输出：

next day of the week having WEDNESDAY for localdate 1998-10-31 is: 1998-11-04

方案二：

// Java program to demonstrate
// TemporalAdjusters.next() method
  
import java.time.*;
import java.time.temporal.*;
  
public class GFG {
    public static void main(String[] args)
    {
  
        // get TemporalAdjuster with the
        // next day of week adjuster
        TemporalAdjuster temporalAdjuster
            = TemporalAdjusters.next(
                DayOfWeek.THURSDAY);
  
        // using adjuster for local date time
        LocalDate localDate
            = LocalDate.of(2029, 12, 11);
        LocalDate nextDOW
            = localDate.with(temporalAdjuster);
  
        // print
        System.out.println(
            "next day of the week having"
            + " THURSDAY for localdate "
            + localDate + " is: "
            + nextDOW);
    }
}

输出：

next day of the week having THURSDAY for localdate 2029-12-11 is: 2029-12-13
