public class ParseOfDuration {
    public static void main(String args[]) {
        // parses the given sequence in this Duration du1 
        // i.e. 1D:1H:20M:10S in a standard format PnDTnHnMn.S
        Duration du1 = Duration.parse("P1DT1H20M10S");

        // Display du1
        System.out.println("Duration.parse(P1DT1H20M10S): " + du1);

        // parsees the given sequence in this Duration du1 
        // i.e. 1D:1H: in a standard format PnDTnHnMn.S
        Duration du2 = Duration.parse("P1DT1H");

        // Display du2
        System.out.println("Duration.parse(P1DT1H): " + du2);

Duration.parse(P1DT1H20M10S): PT25H20M10S
Duration.parse(P1DT1H): PT25H
