如何从文件中读取一字一句？ [英] How to read word by word from file?

问题描述

任何人可以在这里发布一些code我怎么能按字从文件中读取单词？我只知道如何通过专线文件中使用的BufferedReader读线。我想，如果有人用的BufferedReader贴吧。

我这个code解决它：

 的StringBuilder字=新的StringBuilder（）;
                INT I = 0;
                扫描仪输入=新的扫描仪（新的InputStreamReader（a.getInputStream（）））;
                而（input.hasNext（））{
                    我++;
                    如果（我== prefNamePosition）{
                        word.append（prefName）;
                        word.append（）;
                        input.next（）;
                    }
                    其他{
                        word.append（input.hasNext（））;
                        word.append（）;
                    }
                }
 

解决方案

如果你想有一个特殊的值来代替第n个令牌，试试这个：

 而（input.hasNext（））{
    串currentWord = input.next（）;
    如果（++我== prefNamePosition）{
        currentWord = prefName;
    }
    word.append（currentWord）;
    word.append（）;
}
 

Could anybody post here some code how can I read word by word from file? I only know how to read line by line from file using BufferedReader. I'd like if anybody posted it with BufferedReader.

I solved it with this code:

    StringBuilder word = new StringBuilder();
                int i=0;
                Scanner input = new Scanner(new InputStreamReader(a.getInputStream()));
                while(input.hasNext()) {
                    i++;
                    if(i==prefNamePosition){
                        word.append(prefName);
                        word.append(" ");
                        input.next();
                    }
                    else{
                        word.append(input.hasNext());
                        word.append(" ");
                    }
                }

解决方案

If you're trying to replace the nth token with a special value, try this:

while (input.hasNext()) {
    String currentWord = input.next();
    if(++i == prefNamePosition) {
        currentWord = prefName;
    }
    word.append(currentWord);
    word.append(" ");
}
