我如何在 Java的文本档案中处理每五字?
原标题:How do I process each five words in a text file in Java?

奖励所有人;

我有一份文字文件说,“测试.txt”,我想只处理每5个字。

例如,试验。 吨数包括:

<编码> 在表格上,表格中包含旨在与您的文件总看相协调的项目。

我想用头五字: 插入<>/code>,履行某些职能。 接下来的5个字“galleries”包括、do function...etc到文档结束为止的项目。

我想用 j语这样做。 任何想法?

最佳回答

Word groups of 5, then loop over the found matches.

Pattern p = Pattern.compile("(\w*\s?){5}");
String s = "On the Insert tab the galleries include items that are designed to coordinate with the overall look of your document.";
Matcher m = p.matcher(s);
while (m.find()) {
   String words_group = m.group();
   System.out.println(words_group);
}

To split the words_group you can:

words_group.split(" "); // returns String[]

So this pseudo code:

  • Read the file
  • Put the words in a list
  • while( remain unprocessed items )
    • Take five
    • processThem
  • repeat

Could be implemented along the lines.

String fileContent = readFile("test.txt");
List<String> words = splitWordsIntoList( fileContent );
int n = 0;
List<String> five = new ArrayList<String>();
for( String word : words ) { 
  if( n++ < 5 ) { 
     five.add( word );
  } else { 
      n = 0 ;
      process( five );
  }
}

Check out the String.split() method in the SDK. Probably gets you a good ways where you re heading.

你可以把整个文件文本变成一个单一文件,只要你的利益言辞总是按空间分开,就使用一个显示力的象征性手段来制造一系列的言辞。
