问题

我想将下面的代码转换为Lambda表达式:

IntStream.range(0, commentsCount)
         .forEach(i -> System.out.println(js1.getInt("fields.comment.comments[" + i + "].id")));
英文:

I want to convert the below code to a lambda expression

for (int i=0; i < commentsCount ;i++) {
    System.out.println(js1.getInt("fields.comment.comments[" + i + "].id"));
}

你可以尝试在这里使用IntStream,以及一个lambda表达式来构建每个要打印的字符串表达式:

IntStream.range(0, commentsCount)
    .map(i -> js1.getInt("fields.comment.comments[" + i + "].id"))
    .forEach(System.out::println);
英文:

You could try using an IntStream here along with a lambda to build each string expression to be printed:

IntStream.range(0, commentsCount)
    .map(i -> js1.getInt("fields.comment.comments[" + i + "].id"))
    .forEach(System.out::println);
