获取两个时间区间5的倍数的时间点

这个是做数据分析的时候，需要的X轴数据

 直接贴代码了

public static void main(String[] args) {
    LocalDateTime start = LocalDateTime.now().minusHours(20);
    LocalDateTime end =LocalDateTime.now();
    System.out.println(start.getMinute());
    System.out.println(end.getMinute());
    int min = start.getMinute();
    for(int i=0;i<5;i++){
        if(min%5==0){
            System.out.println(min);
            System.out.println(i);
            break;
        }else{
            min+=1;
        }
    }
    //X轴
    List<String> xAxis = new ArrayList<>();
    Duration duration = Duration.between(start,end);
    System.out.println(duration.toMinutes());
    System.out.println(duration.toMinutes()/5);
    if(min==60){
            time = start.plusHours(1).withMinute(0);
        }else{
            time = start.withMinute(min);
        }
    for(int i=0;i<duration.toMinutes()/5;i++){
        //DateUtil.getDateTimeFormat(time)只是一个toString格式化LocalDateTime -> String的工具方法
        xAxis.add(DateUtil.getDateTimeFormat(time));
        time = time.plusMinutes(5);
        if(time.compareTo(end)>0){
            break;
        }
    }
    System.out.println(xAxis);
}

执行打印：
