Output:
PT56H4M
Example 2:
// Java code to illustrate plus() method import java.time.Duration; public class GFG { public static void main(String[] args) { // Duration 1 using parse() method Duration duration1 = Duration.parse("P0DT0H4M"); // Duration 2 using ofHours() method Duration duration2 = Duration.ofDays(5); // Get the duration added // using plus() method System.out.println(duration1 .plus(duration2)); }} |
Output:
