Java中的 LocalTime minusSeconds() 方法及示例

LocalTimeminusSeconds()方法用于从此 LocalTime 中减去指定的 Seconds 值,并将结果作为 LocalTime 对象返回。这个瞬间是不变的。计算在午夜左右结束。

句法:

public LocalTime minusSeconds(long SecondsToSubtract)

参数:该方法接受单个参数SecondsToSubtract ,它是要减去的秒数,可以是负值。

返回值:此方法返回基于此时间减去 Seconds 的LocalTime

下面的程序说明了 minusSeconds() 方法:

方案一:

// Java program to demonstrate
// LocalTime.minusSeconds() method
  
import java.time.*;
  
public class GFG {
    public static void main(String[] args)
    {
  
        // create a LocalTime object
        LocalTime time
            = LocalTime.parse("19:34:50.63");
  
        // print LocalTime
        System.out.println("LocalTime before subtraction: "
                           + time);
  
        // subtract 200 Seconds using minusSeconds()
        LocalTime value = time.minusSeconds(200);
  
        // print result
        System.out.println("LocalTime after subtraction: "
                           + value);
    }
}
输出:
LocalTime before subtraction: 19:34:50.630
LocalTime after subtraction: 19:31:30.630

方案二:

// Java program to demonstrate
// LocalTime.minusSeconds() method
  
import java.time.*;
  
public class GFG {
    public static void main(String[] args)
    {
  
        // create a LocalTime object
        LocalTime time
            = LocalTime.parse("01:00:01");
  
        // print LocalTime
        System.out.println("LocalTime before subtraction: "
                           + time);
  
        // subtract -3400 Seconds using minusSeconds()
        LocalTime value = time.minusSeconds(-3400);
  
        // print result
        System.out.println("LocalTime after subtraction: "
                           + value);
    }
}
输出:
LocalTime before subtraction: 01:00:01
LocalTime after subtraction: 01:56:41
