原文链接http://stackoverflow.com/questions/11208479/how-do-i-initialize-a-byte-array-in-java
有如下几种
1.jdk6
private static final byte[] CDRIVES = javax.xml.bind.DatatypeConverter.parseHexBinary("e04fd020ea3a6910a2d808002b30309d");
2.google code
import com.google.common.io
private static final byte[] CDRIVES = BaseEncoding.base16().decode("e04fd020ea3a6910a2d808002b30309d");
3.
byte[] CDRIVES = hexStringToByteArray("e04fd020ea3a6910a2d808002b30309d");
public static byte[] hexStringToByteArray(String s) {
int len = s.length();
byte[] data = new byte[len / 2];
for (int i = 0; i < len; i += 2) {
data[i / 2] = (byte) ((Character.digit(s.charAt(i), 16) << 4)
+ Character.digit(s.charAt(i+1), 16));
}
return data;
}
