Printstream在文件中跳过第一行的打印

Question

我有这段代码：

    public static void main(String[] args) {
        try {

            String filePath = (args[0]);



            BufferedReader br = new BufferedReader(new FileReader(filePath));
            String strLine = br.readLine();
            //Read File Line By Line and Print the content on the console
             PrintStream out = new PrintStream(new FileOutputStream( //printing output to user specified text file (command line argument: outputfile)
                    args[1]+".txt"));


            while ((strLine = br.readLine()) != null) {
            char [] words = strLine.toCharArray();
            System.out.println (strLine);
                Arrays.sort(words);
                out.println(words);
            }
            //close the streams
            br.close();
            }
            catch(IOException e){
            System.err.println("An IOException was caught, Re-open program and enter correct number of arguments :"+e.getMessage());
            }

    }


}

它完成了我想要的操作，但它正在跳过输入文件的第一行。

比如说输入文件包含这个单词列表： 再见 红色 蓝色

它会输出： EDR 贝鲁

并跳过打印： 贝伊

更改

String strLine = br.readLine();

到

String strLine = null;

当while ((strLine = br.readLine()) != null)执行时，第一行在当前行中被消耗（后来被丢弃）。
