Mas em situações reais, como implementações de segurança, você pode obter mais vantagens em usar as [Ferramentas de segurança integradas (o próximo capítulo)](../security/index.md).

## Erros das dependências e valores de retorno { #dependencies-errors-and-return-values }

Você pode utilizar as mesmas *funções* de dependências que você usaria normalmente.

In this example we use invented custom headers `X-Key` and `X-Token`.

But in real cases, when implementing security, you would get more benefits from using the integrated [Security utilities (the next chapter)](../security/index.md).

## Dependencies errors and return values { #dependencies-errors-and-return-values }

You can use the same dependency *functions* you use normally.

    assertThrows(
        NumberFormatException.class,
        () -> UnsignedBytes.parseUnsignedByte("0", Character.MAX_RADIX + 1));

    // The radix is used as an array index, so try a negative value.
    assertThrows(NumberFormatException.class, () -> UnsignedBytes.parseUnsignedByte("0", -1));
  }

  public void testToString() {
    // We can easily afford to test this exhaustively.
