Assuming the "words" are always separated by a single space. Use String.split()
假设“单词”总是由一个空格分隔。利用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]);

You can do it using BreakIterator classand its static method getSentenceInstance().It Returns a new BreakIterator instance for sentence breaks for the default locale.
您可以使用BreakIterator 类及其静态方法 getSentenceInstance() 来实现。它Returns a new BreakIterator instance for sentence breaks for the default locale。
You can also use getWordInstance(), getLineInstance().. to break words, line...etc
You can also use getWordInstance(), getLineInstance().. to break words, line...etc
eg:
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....

Edited Answer: This is a working code
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();
}

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]);
}

Use a StringTokenizer to separate by spaces or other characters.
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);
}
}
Should print out:
应该打印出来：
Sandy
沙
sells
卖
seashells
贝壳
