• Java OffsetTime类声明
• Java OffsetTime类示例
• Java OffsetTime类示例：getHour()
• Java OffsetTime类示例：getMinute()
• Java OffsetTime类示例：getSecond()

Java OffsetTime类是一个不变的日期时间对象, 它代表一个时间, 通常被视为时, 分, 秒。它继承了Object类并实现Comparable接口。

Java OffsetTime类声明

让我们来看一下java.time.OffsetTime类的声明。

public final class OffsetTime extends Object 
implements Temporal, TemporalAdjuster, Comparable<OffsetTime>, Serializable

Java OffsetTime的方法

Java OffsetTime类示例

import java.time.OffsetTime;
import java.time.temporal.ChronoField;
public class OffsetTimeExample1 {
  public static void main(String[] args) {
    OffsetTime offset = OffsetTime.now();
    int h = offset.get(ChronoField.HOUR_OF_DAY);
    System.out.println(h);
    int m = offset.get(ChronoField.MINUTE_OF_DAY);
    System.out.println(m);
    int s = offset.get(ChronoField.SECOND_OF_DAY);
    System.out.println(s);
  }
}

立即测试

输出：

16
970
58224

Java OffsetTime类示例：getHour()

import java.time.OffsetTime;
public class OffsetTimeExample2 {
  public static void main(String[] args) {
    OffsetTime offset = OffsetTime.now();
    int h = offset.getHour();
    System.out.println(h+ " hour");
  }
}

立即测试

输出：

15 hour

Java OffsetTime类示例：getMinute()

import java.time.OffsetTime;
public class OffsetTimeExample3 {
  public static void main(String[] args) {
    OffsetTime offset = OffsetTime.now();
    int m = offset.getMinute();
    System.out.println(m+ " minute");
  }
}

立即测试

输出：

24 minute

Java OffsetTime类示例：getSecond()

import java.time.OffsetTime;
public class OffsetTimeExample4 {
  public static void main(String[] args) {
    OffsetTime offset = OffsetTime.now();
    int s = offset.getSecond();
    System.out.println(s+ " second");
  }
}

立即测试

输出：

8 second
