方法详细资料

isValidUTF8

public static boolean isValidUTF8(@NonNull
                                  byte[] b)

Indicates whether the contents of the provided array are valid UTF-8.

参数:

b - The byte array to examine. It must not be null.

返回:

true if the byte array can be parsed as a valid UTF-8 string, or false if not.

getBytes

@NonNull
public static byte[] getBytes(@Nullable
                                        String s)

Retrieves a UTF-8 byte representation of the provided string.

参数:

s - The string for which to retrieve the UTF-8 byte representation.

返回:

The UTF-8 byte representation for the provided string.

toString

@NonNull
public static String toString(@NonNull
                                        byte[] b)

Retrieves a string generated from the provided byte array using the UTF-8 encoding.

参数:

b - The byte array for which to return the associated string.

返回:

The string generated from the provided byte array using the UTF-8 encoding.

toString

@NonNull
public static String toString(@NonNull
                                        byte[] b,
                                        int offset,
                                        int length)

Retrieves a string generated from the specified portion of the provided byte array using the UTF-8 encoding.

参数:

b - The byte array for which to return the associated string.

offset - The offset in the array at which the value begins.

length - The number of bytes in the value to convert to a string.

返回:

The string generated from the specified portion of the provided byte array using the UTF-8 encoding.
