Java-Distinct and Concat Methods

Distinct and Concat Methods

The distinct( ) method returns a stream that yields elements from the original stream, in the same order, except that duplicates are suppressed. The stream must obviously remember the elements that it has already seen.

Distinct and Concat Methods

You can concatenate two streams with the static concat( ) method of the Stream class.

        Integer inary2[] = {60,70,80,90,100};
        Stream<Integer> istm1 = Stream.of(inary1);
        Stream<Integer> istm2 = Stream.of(inary2);
        Stream<Integer> istm3 = Stream.concat(istm1, istm2);
        System.out.print("istm1 + istm2 = istm3--> ");
        Integer inary3[] = {10,20,50,20,40,30,80,40,50};
        Stream<Integer> istm4 = Stream.of(inary3);
        Stream<Integer> istm5 = istm4.distinct();
        System.out.print("istm5--> ");
