Java程序将java.util.Date转换为Instant
首先，设置日期-
java.util.Date date = new java.util.Date();
现在，将上述日期转换为Instant-
Instant instant = date.toInstant();
示例
import java.time.Instant;
public class Demo {
public static void main(String[] args) {
java.util.Date date = new java.util.Date();
System.out.println("Date = "+date);
Instant instant = date.toInstant();
System.out.println("java.util.Date to Instant = "+instant);
}
}输出结果
Date = Thu Apr 18 23:32:07 IST 2019 java.util.Date to Instant = 2019-04-18T18:02:07.330Z
