String
literal (for example, "UTF-8"
) can be replaced with
the predefined StandardCharsets.UTF_8
code.
The code after the fix may work faster, because the charset lookup becomes unnecessary.
Also, catching UnsupportedEncodingException
may become unnecessary as well. In this case,
the catch block will be removed automatically.
Example:
try {
byte[] bytes = "str".getBytes("UTF-8");
} catch (UnsupportedEncodingException e) {
}
After quick-fix is applied:
byte[] bytes = "str".getBytes(StandardCharsets.UTF_8);
The inspection is available in Java 7 and later.
