java - jdk中有没有提供纳秒转描述的方法？

Question

比如纳秒数37370571461,如果要转秒数，自己写方法的话，要依次跟1000取整，取余，才能将37370571461纳秒转换成37秒370毫秒571微妙461纳秒，有没有现成的jar包提供了这个方法的实现呢？不需要我再另外自己写方法呢？

Answer 1

There is a ready-made nanosecond to second conversion, but it is not in Chinese, and it cannot express the way of saying nanosecond + millisecond + microsecond. However, your situation is very special. I suggest you convert it directly by intercepting the string. The 3 digits of a certain digit are nanoseconds, the next 3 digits are microseconds, and so on. This is hassle-free and efficient at the same time.
