ArithmeticException-如果发生数字溢出。

以下示例程序旨在说明adjustInto()方法：
示例1:

// Java program to demonstrate 
// Year.adjustInto() method 
  
import java.time.*; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
  
        // create a Year object 
        Year yr 
            = Year.of(2019); 
  
        // 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)yr.adjustInto(date); 
  
        // print instance 
        System.out.println("LocalDate after"
                           + " applying adjustInto method: "
                           + updatedlocal); 
    } 
}

输出：

LocalDate :2007-12-03
LocalDate after applying adjustInto method: 2019-12-03

示例2:

// Java program to demonstrate 
// Year.adjustInto() method 
  
import java.time.*; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
        // create a Year object 
        Year yr 
            = Year.of(2032); 
  
        // create a temporal object 
        LocalDate date = LocalDate.parse("2017-01-13"); 
  
        // print instance 
        System.out.println("LocalDate :"
                           + date); 
  
        // apply adjustInto method of Year class 
        LocalDate updatedlocal = (LocalDate)yr.adjustInto(date); 
  
        // print instance 
        System.out.println("LocalDate after"
                           + " applying adjustInto method: "
                           + updatedlocal); 
    } 
}

输出：

LocalDate :2017-01-13
LocalDate after applying adjustInto method: 2032-01-13
