java - Convert long to "byte-array-ed" text, without heap allocations -

-

I would like to convert a (positive) primitive long to byte [] in my text form , In java

An easy way would be for example: 123 = & gt; "123" = & gt; [49, 50, 51]

Although for a long time it assigns a string to change the string and I am trying to avoid it, for my GC free library, I would like to present it directly on the pre-allocated byte array.

Therefore, my question is how do I go for a byte [] representation for a long time, if I have a string constructor (for example above) I am calling with "123" To clarify, I do not want to convert it into binary form as long as it is in the form of byte [] , but rather literally

Thank you! N

This simple program: 

  long L = 123; Int size = (int) (Math.log10 (l) + 1); Byte [] array = new byte [shape]; For (int i = 0; i

I tested it for the current time in milliseconds and acted as expected: 

  LC = System Syrtetime milliseconds (); ... System.out.println (Arrays.toString (array));

Output: 

  1406485727149 [49, 52, 48, 54, 52, 56, 53, 55, 50, 55, 49, 52, 57 ]

Is it possible to specify a dependency on another gradeal project in the granular (in android studios) outside the current project limits? For example, with a relative path like this: dependence {collection project ('../../ stdlib / dagger'}} MyApp (path / user / foo / workspace / mypad) The app (Path / User / Foo / Workspace / MyPass / App) And I have an Android Library Project with 3 subdomules: stdlib (path is / user / foo / Utilities (Path / User / Foo / Workspace / Stadlib / Utilis) http (Path / User / Foo / Workspace / Stadlib / HT) / Li> What I have to do is compile the Dagger, Util, http module in the MyApp project. The Stidelib Library module under heavy development And MyApp will grow in the form of Growth, so I do not want to push them into a Mewen repository. I am a little change. is likely to add another Gredle projects in some way? I will push the study library into the Maven repository after the source is in search of a temp...
