Java 8 Stream使用If-else逻辑

1. List<Integer> ints = Arrays.asList(1, 2, 3, 4, 5, 6, 7, 8, 9, 10);
2. 
3. ints.stream()
4.     .forEach(i -> {
5. if (i.intValue() % 2 == 0) {
6.             Assert.assertTrue(i.intValue() % 2 == 0);
7.         } else {
8.             Assert.assertTrue(i.intValue() % 2 != 0);
9.         }
10.     });

1. Stream<Integer> evenIntegers = ints.stream()
2.     .filter(i -> i.intValue() % 2 == 0);
3. Stream<Integer> oddIntegers = ints.stream()
4.     .filter(i -> i.intValue() % 2 != 0);
5. 
6. evenIntegers.forEach(i -> Assert.assertTrue(i.intValue() % 2 == 0));
7. oddIntegers.forEach(i -> Assert.assertTrue(i.intValue() % 2 != 0));
