java.net.URLEncoder.encode(String) is deprecated, what should I use instead?

Question

Use the other encode method in URLEncoder:

URLEncoder.encode(String, String)

The first parameter is the text to encode; the second is the name of the character encoding to use (e.g., UTF-8). For example:

System.out.println(
  URLEncoder.encode(
    "urlParameterString",
    java.nio.charset.StandardCharsets.UTF_8.toString()
  )
);

You should use:

URLEncoder.encode("NAME", "UTF-8");

Use the class URLEncoder:

URLEncoder.encode(String s, String enc)

Where :

s - String to be translated.

enc - The name of a supported character encoding.

Standard charsets:

US-ASCII Seven-bit ASCII, a.k.a. ISO646-US, a.k.a. the Basic Latin block of the Unicode character set ISO-8859-1 ISO Latin Alphabet No. 1, a.k.a. ISO-LATIN-1

UTF-8 Eight-bit UCS Transformation Format

UTF-16BE Sixteen-bit UCS Transformation Format, big-endian byte order

UTF-16LE Sixteen-bit UCS Transformation Format, little-endian byte order

UTF-16 Sixteen-bit UCS Transformation Format, byte order identified by an optional byte-order mark

Example:

import java.net.URLEncoder;

String stringEncoded = URLEncoder.encode(
    "This text must be encoded! aeiou áéíóú ñ, peace!", "UTF-8");

The first parameter is the String to encode; the second is the name of the character encoding to use (e.g., UTF-8).
