如何将句子分成两部分？

Question

我有以下类型的句子。我想将句子分成两部分，如下例所示。

例子：

Nimal read/write book/newspaper from his pen.

我想按照上面句子的方式划分并添加到arraylist中。

Nimal/read
Nimal/write
read/book
read/newspaper
write/book
write/newspaper
book/from
newspaper/from
from/his
his/pen.

这意味着我想从下一个单词中得到两个单词短语。我已经划分和添加了句子。但是我不清楚接下来要做什么。

    ArrayList<String> wordArrayList2 = new ArrayList<String>();
    String sentence="Nimal read/write book/newspaper from his pen";
    for(String wordTw0 : sentence.split(" ")) {
        wordArrayList2.add(wordTw0);
    }

Answer 1

一个使用String#split()方法的简单程序。

要遵循的步骤：

1. 根据一个或多个空格分割整个字符串。
2. 迭代数组中的所有字符串，直到长度为 1。
3. 从第 (i) 和 (i+1) 位置一次从数组中获取两个字符串
4. 根据正斜杠拆分两个字符串
5. 迭代两个数组，然后用正斜杠连接单词
6. 添加列表中的所有单词。

示例代码：

String str = "Nimal read/write book/newspaper from his pen.";

ArrayList<String> wordArrayList = new ArrayList<String>();
String[] array = str.split("\\s+"); // split based on one or more space
for (int i = 0; i < array.length - 1; i++) {
    String s1 = array[i];
    String s2 = array[i + 1];

    String[] a1 = s1.split("/"); //split based on forward slash
    String[] b1 = s2.split("/"); //split based on forward slash
    for (String a : a1) {
        for (String b : b1) {
            String word = a + "/" + b;
            wordArrayList.add(word);
            System.out.println(word);
        }
    }
}

输出：

Nimal/read
Nimal/write
read/book
read/newspaper
write/book
write/newspaper
book/from
newspaper/from
from/his
his/pen.
