BASE64Decoder decoder = new BASE64Decoder();
try {
 return decoder.decodeBuffer(fileData);
} catch (IOException e) {
 e.printStackTrace();
...

byte[] Base64Decode(byte[] base64Data)
Base Decode

return Base64.getDecoder().decode(base64Data);

byte[] base64Decode(byte[] data)
Base64 decoding using Base64#getDecoder() decoder

return Base64.getDecoder().decode(data);

byte[] base64Decode(byte[] textBytes)
base Decode

System.out.println("decoding fileBytes");
byte[] bytes = Base64.getDecoder().decode(textBytes);
return bytes;

byte[] base64Decode(char[] a_data)
Decodes a BASE-64 encoded stream to recover the original data.

int l_tempLen = a_data.length;
for (char anA_data1 : a_data) {
 if ((anA_data1 > 255) || s_codes[anA_data1] < 0) {
 --l_tempLen; 
int l_len = (l_tempLen / 4) * 3;
if ((l_tempLen % 4) == 3) {
