requiredCharsets

public static SortedMap<String,Charset> requiredCharsets()

Constructs a sorted map from canonical charset names to charset objects required of every implementation of the Java platform.

From the Java documentation Standard charsets:

返回:

An immutable, case-insensitive map from canonical charset names to charset objects.

toCharset

public static Charset toCharset(Charset charset)

Returns the given Charset or the default Charset if the given Charset is null.

参数:

charset - A charset or null.

返回:

the given Charset or the default Charset if the given Charset is null

toCharset

public static Charset toCharset(String charset)

Returns a Charset for the named charset. If the name is null, return the default Charset.

参数:

charset - The name of the requested charset, may be null.

返回:

a Charset for the named charset

抛出:

UnsupportedCharsetException - If the named charset is unavailable
