Java LocalTime如何比较时间？

Question

Given two LocalTime parameters in Java, I want to be able to compare the two times are see if they are equal (same time). How would I do this?

Answer 1

Compare using LocalTime instance methods: isBefore , isAfter , equals , and compareTo .

LocalTime lt1 = LocalTime.of( 14 , 17 ) ;
LocalTime lt2 = LocalTime.of( 21 , 29 ) ;

boolean same = lt1.equals( lt2 ) ;

Be aware than some java.time classes (other than LocalTime ) carry an isEqual method in addition to equals , with different semantics. For example:

• LocalDate.isEqual versus LocalDate.equals
• ZonedDateTime.isEqual versus ZonedDateTime.equals

Answer 2

Try:

firstLocalTime.equals(secondLocalTime);

.equals() is available for all Object s in Java.
