Java 8 Time API Example: LocalTime, LocalDate and LocalDateTime
September 05, 2014
LocalTime in Java 8
java.time.LocalTime is a time without time- zone that can be represented like hour-minute-second. LocalTime is immutable and represents only time. It does not represent date or time zone.LocalTimeDemo.java
package com.cp.time;
import java.time.Clock;
import java.time.LocalTime;
import java.time.ZoneId;
public class LocalTimeDemo {
public static void main(String[] args) {
LocalTime localt1 = LocalTime.now();
System.out.println(localt1);
LocalTime localt2 = LocalTime.now(Clock.systemDefaultZone());
System.out.println(localt2);
System.out.println(LocalTime.now(ZoneId.of("Indian/Cocos")));
System.out.println(LocalTime.now(ZoneId.of("America/Caracas")));
System.out.println(LocalTime.now(ZoneId.of("Pacific/Norfolk")));
}
}
Find the output.

LocalDate in Java 8
java.time.LocalDate is an immutable class that represents local date like YYYY-MM-dd. This class does not store time and time zone.LocalDateDemo.java
package com.cp.time;
import java.time.Clock;
import java.time.LocalDate;
import java.time.ZoneId;
public class LocalDateDemo {
public static void main(String[] args) {
LocalDate localDate1 = LocalDate.now();
System.out.println(localDate1);
LocalDate localDate2 = LocalDate.now(Clock.systemDefaultZone());
System.out.println(localDate2);
System.out.println(LocalDate.now(ZoneId.of("Indian/Cocos")));
System.out.println(LocalDate.now(ZoneId.of("America/Caracas")));
System.out.println(LocalDate.now(ZoneId.of("Pacific/Norfolk")));
}
}
Find the output.

LocalDateTime in Java 8
java.time.LocalDateTime is an immutable class that represents the combination of local date and local time like 2009-11-06T10:18:30. LocalDateTime does not represent time zone.LocalDateTimeDemo.java
package com.cp.time;
import java.time.Clock;
import java.time.LocalDateTime;
import java.time.ZoneId;
public class LocalDateTimeDemo {
public static void main(String[] args) {
LocalDateTime localdt1 = LocalDateTime.now();
System.out.println(localdt1);
LocalDateTime localdt2 = LocalDateTime.now(Clock.systemDefaultZone());
System.out.println(localdt2);
System.out.println(LocalDateTime.now(ZoneId.of("Indian/Cocos")));
System.out.println(LocalDateTime.now(ZoneId.of("America/Caracas")));
System.out.println(LocalDateTime.now(ZoneId.of("Pacific/Norfolk")));
}
}
Find the output.
