Java 类、接口或枚举预期错误？

每次我编译的时候，它都会说这段代码有21个错误？我真的被困在这一点上。。。我什么都试过了。如果有人能帮助我，那就太好了

代码如下：

//Normal-Player End

public static void archiveLogs(Player player, String[] cmd) {
    try {
        if (player.getRights() < 1)
            return;
        String location = "";
        if (player.getRights() >= 5) {
            location = "data/logs/admin" + player.getUsername() + ".txt";
        } else if (player.getRights() == 4) {
            location = "data/logs/mod" + player.getUsername() + ".txt";
        }
        String afterCMD = "";
        for (int i = 1; i < cmd.length; i++)
    afterCMD += cmd[i] + ((i == cmd.length - 1) ? "" : " ");
        BufferedWriter writer = new BufferedWriter(new FileWriter(location,
                true));
        writer.write("[" + now("dd MMMMM yyyy 'at' hh:mm:ss z") + "] - ::"
                + cmd[0] + " " + afterCMD);
        writer.newLine();
        writer.flush();
        writer.close();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

public static String now(String dateFormat) {
    Calendar cal = Calendar.getInstance();
    SimpleDateFormat sdf = new SimpleDateFormat(dateFormat);
    return sdf.format(cal.getTime());
}

private Commands() {

}

//正常播放结束
公共静态void archiveLogs（播放器，字符串[]cmd）{
试一试{

返回；
字符串位置=”；
如果（player.getRights（）>=5）{

下面是我的编译器所说的：
