如何逐行解析到文本文件?

我试图逐行读取字符串,并通过FileWriter将其写入文本文件。该文件必须覆盖,因此我不能在FileWriter中使用true作为第二个参数。在String到达writeToFile方法之前,我可以使用=来解析String,但是我只得到了最后一个String行,因为它被覆盖了。使用+ =,它获得所有字符串的一行字符串。我也尝试将String()拆分为多个,但它是相同的。我怎么能改变下面的代码,逐行获得输出?

由于

   private void writeToFile(File cf, String ln) throws IOException {
    //true won't work as the data must be overwrite.  
    FileWriter fw = new FileWriter(cf);
    try (BufferedWriter bw = new BufferedWriter(fw)) {
         // I got just one string all at the same line. Or just the last-
         // String
         bw.write(ln);
         bw.newLine();
         bw.flush();
    }
   }

private void writeToFile(File cf, String ln) throws IOException { //true won't work as the data must be overwrite. FileWriter fw = new FileWriter(cf); try (BufferedWriter bw = new BufferedWriter(fw)) { // I got just one string all at the same line. Or just the last- // String bw.write(ln); bw.newLine(); bw.flush(); } }
