Java将string内容写入到TXT文件

    private static String filePath = "E:\\test.txt";

    private static void saveAsFileWriter(String content) {
        FileWriter fwriter = null;
        try {
            // true表示不覆盖原来的内容，而是加到文件的后面。若要覆盖原来的内容，直接省略这个参数就好
            fwriter = new FileWriter(filePath, true);
            fwriter.write(content);
        } catch (IOException ex) {
            ex.printStackTrace();
        } finally {
            try {
                fwriter.flush();
                fwriter.close();
            } catch (IOException ex) {
                ex.printStackTrace();
            }
        }
    }
