Method

Stringdecode(String bytes)
decode 
ByteArrayOutputStream baos = new ByteArrayOutputStream(bytes.length() / 2);
for (int i = 0; i < bytes.length(); i += 2)
    baos.write(hexString.indexOf(bytes.charAt(i)) << 4 | hexString.indexOf(bytes.charAt(i + 1)));
return new String(baos.toByteArray());
byte[]decode(String cipherText)
decode 
return DECODER.decodeBuffer(cipherText);
byte[]decode(String in)
Base 64 decodes the specified string. 
int len = in.length();
if (len % 4 != 0) {
    throw new IOException("Length of base 64 encoded string must be a multiple of 4");
while (len > 0 && in.charAt(len - 1) == '=') {
    len--;
int oLen = (len * 3) / 4;
...
Stringdecode(String name)
decode 
StringBuilder sb = new StringBuilder();
for (int i = 0; i < name.length(); i++) {
    char c = name.charAt(i);
    if (c != '_')
        sb.append(c);
    else {
        c = (char) Integer.parseInt(name.substring(i + 1, i + 3), 16);
        sb.append(c);
...
JsonStructuredecode(String s)
Obtain a JsonStructure from a String. 
if (s == null || s.isEmpty()) {
    return null;
final StringReader r = new StringReader(Objects.requireNonNull(s));
try (JsonReader jr = Json.createReader(r)) {
    return jr.read();
JsonNodedecode(String s)
decode 
return om.readTree(s);
Stringdecode(String s)
decode 
boolean needToChange = false;
StringBuffer sb = new StringBuffer();
int numChars = s.length();
int i = 0;
while (i < numChars) {
    char c = s.charAt(i);
    switch (c) {
    case '+':
...
Stringdecode(String s)
Copied from URLDecoder.java 
StringBuilder sb = new StringBuilder();
for (int i = 0; i < s.length(); i++) {
    char c = s.charAt(i);
    switch (c) {
    case '+':
        sb.append(' ');
        break;
    case '%':
...
Stringdecode(String s)
decode 
if (s != null) {
    return new String(xorWithKey(base64Decode(s), "HELIUMV".getBytes()));
} else {
    return null;
Tdecode(String s)
decode 
byte[] decode = Base64.getDecoder().decode(s);
try (ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(decode);
        ObjectInputStream si = new ObjectInputStream(byteArrayInputStream)) {
    return (T) si.readObject();
} catch (ClassNotFoundException | IOException e) {
    throw new UnsupportedOperationException(e);
