Question

这是我的代码：

import java.util.Calendar;

public class Time {
    private int hour;
    private int minute;
    private int second;

    public static void main (String args[]){
        Time time1 = new Time();
        Time time2 = new Time();

        time2.setTime(555550000L);

        System.out.println("First Time: "+time1.hour+":"+time1.minute+":"+time1.second+);
        System.out.println("Second Time: "+time2.hour+":"+time2.minute+":"+time2.second+);
    }

    public Time() {
        Calendar calen= Calendar.getInstance();
        hour=calen.get(Calendar.HOUR_OF_DAY);
        minute=calen.get(Calendar.MINUTE);
        second=calen.get(Calendar.SECOND);
    }

    public void setTime(long elapseTime){
        Calendar c=Calendar.getInstance();
        c.setTimeInMillis(elapseTime);
        hour=c.get(Calendar.HOUR_OF_DAY);
        minute=c.get(Calendar.MINUTE);
        second=c.get(Calendar.SECOND);
    }
}

我一直收到以下错误，但我不知道如何修复它们。救命？

Time.java:14：非法开始表达 System.out.println（＆＃34;第一次：＆＃34; + time1.hour +＆＃34;：＆＃34; + time1.minute +＆＃34;：＆＃34; + time1.second +）
Time.java:15：非法开始表达 System.out.println（＆＃34;第二次：＆＃34; + time2.hour +＆＃34;：＆＃34; + time2.minute +＆＃34;：＆＃34; + time2.second +） ; ^

Answer 1

删除最后的+。

System.out.println("First Time: "+time1.hour+":"+time1.minute+":"+time1.second);
System.out.println("Second Time: "+time2.hour+":"+time2.minute+":"+time2.second);

Answer 2

它是System.out.println行末尾的尾随+。你必须删除它，一切都会好的。
