我有一个文本文件作为输入，我有n个段落，每个段落都有换行符。我需要将每个段落替换为一行

让我考虑一个小例子

我的意见是：

it helps them to identify the solutions for unsolved problems

我的输出应该是：

Stackoverflow is the best site for java novice beginners  it helps them to identify the solutions for unsolved problems Please help me to fix it.

我尝试使用split，regex。什么都不能救我。：（

如果有任何内容，我需要用空格替换新行

请帮忙。

首先抱歉我的英语。我想你可以读取每一行，然后在一个字符串中连接每一行。像这样：

File yourFile= null;
        FileReader fr = null;
        BufferedReader br = null;
      //Here you will store the merged paragraphs
        String mergedParagraphs = new String();
        try
        {

            yourFile= new File ("path to your file");
            fr = new FileReader (yourfile);
            br = new BufferedReader(fr);

            String line;

            while((line=br.readLine())!=null)
            {
                mergedParagraphs = mergedParagraphs + line;
            }
        }
        catch(Exception e)
        {
            e.printStackTrace();
        }
        finally
        {
            // Here the input file is closed
            try
            {
                if( null != fr )
                {
                    fr.close();
                }
            }catch (Exception e2)
            {
                e2.printStackTrace();
            }
        }
    }

我希望它可以帮到你
