Where to get “UTF-8” string literal in Java?

Question

I\'m trying to use a constant instead of a string literal in this piece of code:

new InputStreamReader(new FileInputStream(file), \"UTF-8\")

Answer 1

In Java 1.7+

Do not use "UTF-8" string, instead use Charset type parameter:

import java.nio.charset.StandardCharsets

...

new InputStreamReader(new FileInputStream(file), StandardCharsets.UTF_8);
