Public Methods
public static T[] emptyArray(Class kind)
Returns an empty array of the specified type. The intent is that
it will return the same empty array every time to avoid reallocation,
although this is not guaranteed.
public static boolean equals(byte[] array1, byte[] array2, int length)
Checks if the beginnings of two byte arrays are equal.
Parameters
| array1 | the first byte array |
|---|---|
| array2 | the second byte array |
| length | the number of bytes to check |
Returns
- true if they're equal, false otherwise
