Description

The list of methods to do URL Encode are organized into topic(s).

Method

Stringencode(String s)
Equivalent to #encode(String,String) with second parameter set to the "UTF-8" encoding. 
return encode(s, UTF8);
Stringencode(String s)
URL Encodes the given String s using the UTF-8 character encoding. 
if (s == null)
    return null;
try {
    return URLEncoder.encode(s, "UTF-8");
} catch (UnsupportedEncodingException e) {
return null;
Stringencode(String s)
Like URLEncoder.encode, except translates spaces into %20 instead of + 
if (s == null) {
    return "";
try {
    return URLEncoder.encode(s, "UTF-8").replaceAll("\\+", "%20");
} catch (UnsupportedEncodingException e) {
    return URLEncoder.encode(s).replaceAll("\\+", "%20");
Stringencode(String s)
URL encoding. 
try {
    if (s != null)
        return URLEncoder.encode(s, "UTF-8");
    else
        return s;
} catch (UnsupportedEncodingException e) {
    return s;
Stringencode(String s, String enc)
Pass through to the java.net.URLEncoder . 
if (urlEncode != null) {
    try {
        return (String) urlEncode.invoke(s, new Object[] { s, enc });
    } catch (IllegalAccessException e) {
    } catch (InvocationTargetException e) {
        if (e.getTargetException() instanceof UnsupportedEncodingException) {
            throw (UnsupportedEncodingException) e.getTargetException();
        } else if (e.getTargetException() instanceof RuntimeException) {
...
Stringencode(String s, String encoding)
Calls java.net.URLEncoder.encode(String, String) via reflection, if we are running on JRE 1.4 or later, otherwise reverts to the deprecated URLEncoder.encode(String) method. 
Class c = URLEncoder.class;
String result = null;
try {
    Method m = c.getDeclaredMethod("encode", STRING_ARGS_2);
    try {
        result = (String) m.invoke(null, new Object[] { s, encoding });
    } catch (InvocationTargetException e) {
        e.printStackTrace();
...
Stringencode(String source)
encode 
StringBuffer sb = new StringBuffer();
encode(source, sb);
return sb.toString();
Stringencode(String src, String srcCode, String destCode)
encode 
try {
    byte[] strby = src.getBytes(srcCode);
    String dest = new String(strby, destCode);
    return dest;
} catch (UnsupportedEncodingException e) {
    e.printStackTrace();
return null;
...
Stringencode(String str)
encodes the given string using URLEncoder. 
try {
    return java.net.URLEncoder.encode(str, "UTF-8");
} catch (java.io.UnsupportedEncodingException ue) {
    return str;
Stringencode(String str)
Encode the specified string. 
try {
    return URLEncoder.encode(str, encode);
} catch (UnsupportedEncodingException e) {
    return str;
