Is System.arraycopy safe when the source and destination are the same array?

開發十年,就只剩下這套架構體系了! >>>   

/***
 *  From java doc: If the src and dest arguments refer to the same array object,
 *  then the copying is performed as if the components at positions srcPos through
 *  srcPos+length-1 were first copied to a temporary array with length components
 *  and then the contents of the temporary array were copied into positions destPos
 *  through destPos+length-1 of the destination array
