Pair<String, Integer> pair = Pair.with("Pack", 33) ; Quartet<String, Integer, String, Double> quartet = Quartet .with("pack", 33, "price",2.3D) ; Pair<String, Integer> user = new Pair<>("Pack", 33) ; List<String> listOf4Names = Arrays.asList("A1","A2","A3","A4"); Quartet<String, String, String, String> retQuartet = Quartet .fromCollection(listOf4Names) ; // 输出：[A1, A2, A3, A4] System.out.println(retQuartet) ; // 输出：[A3, A4] Pair<String, String> pair1 = Pair.fromIterable(listOf4Names, 2) ; System.out.println(pair1); Pair<String, Integer> pair = Pair.with("Pack", 33) ; System.out.printf("姓名: %s%n", pair.getValue0()) ; System.out.printf("年龄: %s%n", pair.getValue1()) ;
