When to encode a string to UTF-8 in Java?
When working with Strings in Java, we oftentimes need to encode them to a specific charset, such as UTF-8. UTF-8 represents a variable-width character encoding that uses between one and four eight-bit bytes to represent all valid Unicode code points.
Is the stringwriter withencoding does not compile?
Your code does not compile — StringWriterWithEncodingdoes not have a parameterless constructor. Or, maybe the version you are actually does have a parameterless constructor which leaves encodingat its default (null) value, meaning Encodingreturns null?
How do you encode a string in Java?
