Nested Class Summary

static class

Encoding.UnsupportedException This is an unchecked exception.

Method Summary

static byte[]	getBytes(char ch, String enc) Returns the byte representation of the character ch in the specified encoding enc.
static boolean	isSupportedEncoding(String enc) Returns true if the character encoding enc is supported by the host JVM.
static String	toHex(byte b) Returns the hexadecimal representation of the byte, with the return value ranging from "0x00" to "0xFF".
static String	toHex(char ch) Returns the hexadecimal representation of the character.

Method Detail

toHex

public static String toHex(char ch)

Returns the hexadecimal representation of the character.

For example, toHex('?') is "0x0C03" and toHex('A') is "0x0041".

toHex

public static String toHex(byte b)

Returns the hexadecimal representation of the byte, with the return value ranging from "0x00" to "0xFF".

For example, toHex((byte) 126) is "0x7E" and toHex((byte) -2) is "0xFE".

isSupportedEncoding

public static boolean isSupportedEncoding(String enc)

Returns true if the character encoding enc is supported by the host JVM.

getBytes

public static byte[] getBytes(char ch,
                              String enc)

Returns the byte representation of the character ch in the specified encoding enc. If the specified encoding is "UTF-16", the result is a platform-dependent two-byte sequence, with the byte-order mark (BOM) stripped out.

Throws:

Encoding.UnsupportedException
