Is there a function in Microsoft Office Excel that converts numeric type to string type?
Value function
Function: Converts a text string representing a number to a number.
Call Format: = Value (Text)
Text is a reference text, or a reference to a cell that needs text conversion. Text can be any constant, date or time format recognized in Microsoft Excel.
If the text is not in these formats, the function value will return an error value.

30-point solution: long value is converted into time type, and I wrote a method myself, just use it directly.
Common class test {
The public static void main(String[] args) throws an exception {
Long time = 25978000;
system . out . println(getTime(time))；
}
Public static string getTime (long time)
String str =
Time = time/1000;
Int s = (int) (time% 60);
Int m = (int) (time/60% 60);
int h =(int)(time/3600)；
Str = h+ hours +m+ minutes +s+ seconds;
Returns a string;

} catch (ParseException e) {
e . printstacktrace()；
}
