Isso é bastante útil quando você precisa:

* Definir uma lógica compartilhada (mesmo formato de código repetidamente).
* Compartilhar conexões com banco de dados.
* Aplicar regras de segurança, autenticação, papéis de usuários, etc.
* E muitas outras coisas...

Tudo isso, enquanto minimizamos a repetição de código.

## Primeiros passos { #first-steps }

        assertEquals(expectedString, packet.toString());

        // Test recordName == questionName branch in toString
        packet.recordName = packet.questionName;
        expectedString =

        NetbiosAddress nb = mock(NetbiosAddress.class);
        when(addr.unwrap(NetbiosAddress.class)).thenReturn(nb);
        when(nb.getNameType()).thenReturn(0x1d); // workgroup code
        // getFirstAddress branch: host given and path non-root -> possibleNTDomain=false
        when(nsc.getAllByName(eq("server"), eq(false))).thenReturn(new Address[] { addr });
        SmbResourceLocatorImpl workgroupLike = locator("smb://server/");

     */

    if (approxCmp > 0) {
      /*
       * The code is written so that even completely incorrect approximations will still yield the
       * correct answer eventually, but in practice this branch should almost never be entered, and
       * even then the loop should not run more than once.
       */
      do {
        approxLog10--;
        approxPow = approxPow.divide(BigInteger.TEN);

Pero aún así, la experiencia final no es la mejor. 😞

Para un ejemplo más "de la vida real" de esto, imagina un banco.

Hasta hace poco, la mayoría de los bancos tenían múltiples cajeros 👨‍💼👨‍💼👨‍💼👨‍💼 y una gran fila 🕙🕙🕙🕙🕙🕙🕙🕙.

Todos los cajeros haciendo todo el trabajo con un cliente tras otro 👨‍💼⏯.
