java - Java如何将一个句子分成几部分？

Question

我怎样才能把一个句子分成"He and his brother playing football."几个部分，如"He and"，、和。是否可以通过使用Java来做到这一点？"and his""his brother""brother playing""playing football"

Answer 1

假设“单词”总是由一个空格分隔。采用String.split()

String[] words = "He and his brother playing football.".split("\\s+");
for (int i = 0, l = words.length; i + 1 < l; i++)
        System.out.println(words[i] + " " + words[i + 1]);

Answer 2

您可以使用BreakIterator 类及其静态方法 getSentenceInstance() 来完成。 它Returns a new BreakIterator instance for sentence breaks for the default locale。

You can also use getWordInstance(), getLineInstance().. to break words, line...etc

例如：

BreakIterator boundary = BreakIterator.getSentenceInstance();

boundary.setText("Your_Sentence");

int start = boundary.first();

int end = boundary.next();

Iterate over it... to get the Sentences....

编辑答案：This is a working code

String sent = "My name is vivek. I work in TaxSmart";
        BreakIterator bi = BreakIterator.getSentenceInstance();
        bi.setText(sent);
        int index = 0;
        while (bi.next() != BreakIterator.DONE) {
        String sentence = sent.substring(index, bi.current());
        System.out.println("Sentence: " + sentence);
        index = bi.current();
        }

Answer 3

String str="He and his brother playing football";

    String [] strArray=str.split(" ");
    for(int i=0;i<strArray.length-1 ;i++)
    {
        System.out.println(strArray[i]+" "+strArray[i+1]);
    }

Answer 4

使用 StringTokenizer 以空格或其他字符分隔。

import java.util.StringTokenizer;

public class Test {

         private static String[] tokenize(String str) {
            StringTokenizer tokenizer = new StringTokenizer(str);
        String[] arr = new String[tokenizer.countTokens()];
        int i = 0;
        while (tokenizer.hasMoreTokens()) {
        arr[i++] = tokenizer.nextToken();
        }
        return arr;
     }

    public static void main(String[] args) {
        String[] strs = tokenize("Sandy sells seashells by the sea shore.");
        for (String s : strs)
            System.out.println(s);
    }
}

应该打印出来：

沙

卖

贝壳

经过

这

海

支撑。

可能是也可能不是你所追求的。
