Question

假设我有结构如下的字符串

This is sentence one.
this is sentence two.

This is sentence three.
This is sentence 4.

This is sentence 5.
This is sentence 6.

我的要求是在遇到两个空行后获取文本。

我只想要这个 这是第5句。 这是第 6 句。

如何在 JAVA 中实现此目的？

这是一种简单而丑陋的方法:

    public static void main(String[] args) throws FileNotFoundException {
    Scanner in = new Scanner(new FileReader("input.txt"));
    String empty = "";
    int counter = 0;


    while (in.hasNextLine()) {
        String temp = in.nextLine();
        if (temp.equalsIgnoreCase(empty)) {
            counter++;
            if (counter == 2) {
                System.out.println(in.nextLine());
                System.out.println(in.nextLine());
                System.exit(1);
            }
        }
    }
}
