How do I encode a string in Java?

In Java, you can use the java.net.URLEncoder class to encode a string. For example:

String encodedString = URLEncoder.encode(originalString, StandardCharsets.UTF_8);

What if I need to decode it back?

To decode a string, you can use the java.net.URLDecoder class like this:

String decodedString = URLDecoder.decode(encodedString, StandardCharsets.UTF_8);

Are there any other encoding methods I should know about?

Yes, besides URL encoding, you might also want to look into Base64 encoding, which is useful for encoding binary data.

Can you show me an example of Base64 encoding?

Sure! You can use java.util.Base64 for Base64 encoding:

String base64Encoded = Base64.getEncoder().encodeToString(originalString.getBytes(StandardCharsets.UTF_8));
