| 1 | + | La palabra reservada **constructor** es parte de la programación orientada a objetos y se utiliza para inicializar una clase. Las clases simples que no requieren inicialización, no necesitan un constructor. Una clase auto-escrita que no tiene ningún constructor puede heredar el constructor de su clase principal (si tiene un constructor). | |
