Java中的 Duration equals(Duration) 方法及示例
Java包中的Duration类的equals(Duration)方法用于检查这个duration是否等于作为参数传入的duration。
句法:
public boolean equals(Duration otherDuration)
参数:此方法接受参数otherDuration ,该参数是与此持续时间进行比较的持续时间。
返回值:此方法返回一个布尔值,显示此 Duration 是否等于 otherDuration。
下面的示例说明了 Duration.equals() 方法:
示例 1:
// Java code to illustrate equals() method
import java.time.Duration;
public class GFG {
public static void main(String[] args)
{
// Duration using parse() method
Duration duration1
= Duration.parse("P2DT3H4M");
// Duration using ofDays() method
Duration duration2
= Duration.ofDays(10);
// Compare the durations
// using equals() method
System.out.println(duration1
.equals(duration2));
}
}
输出:
false
示例 2:
// Java code to illustrate equals() method
import java.time.Duration;
public class GFG {
public static void main(String[] args)
{
// Duration using ofHours() method
Duration duration1
= Duration.ofHours(5);
// Duration using ofHours() method
Duration duration2
= Duration.ofHours(5);
// Compare the durations
// using equals() method
System.out.println(duration1
.equals(duration2));
}
}
输出:
true
示例 3:
// Java code to illustrate equals() method
import java.time.Duration;
public class GFG {
public static void main(String[] args)
{
// Duration using ofDays() method
Duration duration1
= Duration.ofDays(5);
// Duration using ofHours() method
Duration duration2
= Duration.ofHours(5);
// Compare the durations
// using equals() method
System.out.println(duration1
.equals(duration2));
}
}
输出:
false
