java8如何取数组中对象的值？？？

Question

有这样一个数组：
[{0=1}, {0=2}, {0=3}, {0=4}, {0=5}, {0=6}, {0=7}, {0=8}, {0=9}, {0=10}, {0=11}, {0=12}, {0=13}, {0=14}, {0=15}, {0=16}, {0=17}, {0=18}, {0=19}]
现在只想要[1,2,3,4...]要怎么方便取出来啊？？？

Answer 1

List<String> collect = arr.stream().map(x->x.split("=")[1]).collect(Collectors.toList());
