Java 等价于：String.format(“{0:D9}”, Result);

Question

Does anyone know the Java equivalent of the C# format of:

String.format("{0:D9}", Result);

Here what it does: http://www.java2s.com/Code/CSharp/Data-Types/doublenumberformat0C0D90E0F30N0X0x.htm

This little problem is killin' me...

Answer 1

As far as I understand the documentation D9 means "format as a decimal number with at least 9 digits, left-padding with 0 if necessary).

The equivalent in Java format Strings would be %09d :

System.out.println(String.format("%09d", 1234));

This prints

000001234
