java.time.Instant.compareTo(Instant otherInstant)
方法將此瞬間與指定的瞬間進行比較。
以下是java.time.Instant.compareTo(Instant otherInstant)
方法的宣告。
public int compareTo(Instant otherInstant)
otherInstant
- 比較的另一個瞬間,而不是null
。比較器值,如果更小則為負,如果更大則為正。
NullPointerException
- 如果otherInstant
為null
。以下範例顯示了java.time.Instant.compareTo(Instant otherInstant)
方法的用法。
package com.yiibai;
import java.time.Instant;
import java.time.OffsetDateTime;
import java.time.ZoneId;
import java.time.ZoneOffset;
import java.time.ZonedDateTime;
import java.util.Set;
public class InstantDemo {
public static void main(String[] args) {
Instant instant = Instant.parse("2017-02-03T10:37:30.00Z");
System.out.println("Instant #1: " + instant);
Instant instant1 = Instant.parse("2017-03-03T10:37:30.00Z");
System.out.println("Instant #2: " + instant1);
int result = instant.compareTo(instant1);
System.out.println(result >1 ? "Instant #1 is greater than Instant #2."
:"Instant #2 is greater than Instant #1.");
}
}
編譯並執行上面的程式,這將產生以下結果 -
Instant #1: 2017-02-03T10:37:30Z
Instant #2: 2017-03-03T10:37:30Z
Instant #2 is greater than Instant #1.
