java - 在 Java 中按字数拆分句子

Question

如何将一个句子分成两个词数相等的组？

 Sentence(odd words count) :
         This is a sample sentence
 Output: part[0] = "This is a "
         part[1] = "sample sentence"

Sentence(even words count) : 
        This is a sample sentence two
 Output: part[0] = "This is a "
         part[1] = "sample sentence two"

我试图将整个句子拆分成单词，获取第((空格总数/2)+ 1)个空格的索引并应用子字符串。但是它很乱，我无法得到想要的结果。

使用 Java8 的非常简单的解决方案

    String[] splitted = test.split(" ");
    int size = splitted.length;
    int middle = (size / 2) + (size % 2);
    String output1 =  Stream.of(splitted).limit(middle).collect(Collectors.joining(" "));
    String output2 =  Stream.of(splitted).skip(middle).collect(Collectors.joining(" "));
    System.out.println(output1);
    System.out.println(output2);

2 个测试字符串的输出是:

This is a
sample sentence
This is a
sample sentence two
