### Target language

Translate to Portuguese (Português).

Language code: pt.

For instructions or titles in imperative, keep them in imperative, for example "Import FastAPI" to "Importe o FastAPI".

Keep existing translations as they are if the term is already translated.

 * <p>This class can't depend on other Guava code. If we were to load this class in the same class
 * loader as the rest of Guava, this thread would keep an indirect strong reference to the class
 * loader and prevent it from being garbage collected. This poses a problem for environments where

  private static class WithPublicConstants {
    @Keep public static final WithPublicConstants FIRST = new WithPublicConstants();

    // To test that we pick the first constant alphabetically
    @Keep public static final WithPublicConstants SECOND = new WithPublicConstants();
  }

  private static class FirstConstantIsNull {
    // To test that null constant is ignored

        List<FileEntry> entries = Arrays.asList(entry("keep1", SmbConstants.TYPE_SHARE), entry("skip1", SmbConstants.TYPE_SHARE),
                entry("keep2", SmbConstants.TYPE_SHARE));

        // Filter accepts names starting with "keep"
        when(filter.accept(any())).thenAnswer(inv -> {
            SmbResource res = inv.getArgument(0);
            return res.getName().startsWith("keep");
        });

For technical terms in English that don't have a common translation term, use the original term in English.


### Content of code snippets

Do not translate the content of code snippets, keep the original in English. For example, «`list`», «`dict`», keep them as is.


### Content of code blocks

Do not translate the content of code blocks, except for comments in the language which the code block uses.

Examples:
