方法详细资料

getModifiedUtf8Length

public static int getModifiedUtf8Length(String string)

Returns the length of the modified UTF-8 byte array representation of the given string.

getModifiedUtf8Bytes

public static byte[] getModifiedUtf8Bytes(String string)

Returns the modified UTF-8 byte array representation of the given string.

Note: surrogate pairs are encoded separately as three byte values as requested by the modified UTF-8 specification. This method is suited for encoding strings stored in class files, dex files or native libraries.

getString

public static String getString(byte[] modifiedUtf8Bytes)

Returns the String representation of the given modified UTF-8 byte array.

getString

public static String getString(byte[] modifiedUtf8Bytes,
 int startIndex,
 int endIndex)

Returns the String representation of the given modified UTF-8 byte array.

join

public static String join(String separator,
 String... strings)

Joins the given strings using the provided separator.

参数:

separator - The separator to use.

strings - The strings to join.

返回:

The input strings, concatenated together using the separator

toHexString

public static String toHexString(byte[] bytes)

Returns the hexadecimal representation of the given byte array.

toHexString

public static String toHexString(byte[] bytes,
 String separator,
 boolean upperCase)

Returns the hexadecimal representation of the given byte array.

escapeControlCharacters

public static String escapeControlCharacters(String input)

Escapes control characters (\n, \r, \b, \t, \f).

listToString

public static String listToString(List<String> stringList)

Converts a List of Strings to a nicely readable format. Example: ["foo", "bar", "baz"].
