How to convert String to LocalTime in Java

In Java, we can use the LocalTime.parse(CharSequence text) static method to convert a String in ISO-8601 extended local time format to a LocalTime object as the example Java code below.

ConvertStringToLocalTimeExample1.java 

import java.time.LocalTime;

public class ConvertStringToLocalTimeExample1 {
    public static void main(String... args) {
        LocalTime localTime1 = LocalTime.parse("14:40:55.666555444");
        LocalTime localTime2 = LocalTime.parse("14:40:55");

        System.out.println("localTime1: " + localTime1);
        System.out.println("localTime2: " + localTime2);
    }
}
The output as below. 
localTime1: 14:40:55.666555444
localTime2: 14:40:55

How to convert String to LocalTime with custom time format

Using the LocalTime.parse(CharSequence text, DateTimeFormatter formatter) method we can convert a time String in specified format to LocalTime object as following example Java code.

ConvertStringToLocalTimeExample2.java 

import java.time.LocalTime;
import java.time.format.DateTimeFormatter;

public class ConvertStringToLocalTimeExample2 {
    public static void main(String... args) {
        DateTimeFormatter dateTimeFormatter = DateTimeFormatter.ofPattern("HH-mm-ss-SSSSSSSSS");

        LocalTime localTime = LocalTime.parse("14-40-55-666555444", dateTimeFormatter);

        System.out.println(localTime);
    }
}
The output as below. 
14:40:55.666555444
