你知道如何使用FileReader读取文件。
还考虑将整个文件读入StringBuider对象然后替换所有文件带逗号的空格。您可能需要在结束时进行一些内务管理。
Do you know how to read a file using FileReader then.
Also consider reading the whole file into a StringBuider object and then replacing all spaces with commas. You may need to do a bit of housekeeping at the end.
您在读取文件时是否可以使用字符串标记符，然后只输出token1，token2，token3，token4？
Could you use string tokenizer when reading in the file, then just output token1,token2,token3,token4?

嗨管理员，
Hi Admin,
I know how to read the file using FileReader/BufferedReader. But I have the problem with the logic of how to add comma and replace the whitespaces between each fields. Please if you can write a simple code so that I can learn from it. I appreciate it very much.
