LocalTimeDemo1.java

import java.time.LocalTime;

public class LocalTimeDemo1

{

    public static void main(String[] args)

    {

        LocalTime time1 = LocalTime.parse("05:30:30");

        System.out.println(time1);

        LocalTime time2 = LocalTime.parse("06:35:30");

        System.out.println(time2);

        /*
         * Parameters:
         * 
         * other - the other time to compare to, not null
         * 
         * Returns:the comparator value, negative if less, positive if
         * greater
         */

        int value = time1.compareTo(time2);

        System.out.println(value);

    }

}

Output

05:30:30

06:35:30

-1
