Programa de patrons Java millora l'habilitat de codificació, la lògica i els conceptes de bucle. Es demana sobretot a Entrevista de Java per comprovar la lògica i el pensament del programador. Podem imprimir a Programa de patrons Java en diferents dissenys. Per aprendre el programa de patrons, hem de tenir un coneixement profund del bucle Java, com ara per bucle Fer mentre bucle. En aquest apartat, aprendrem com imprimir un patró en Java .
Hem classificat el Java programa de patrons en tres categories:
Abans de passar als programes de patrons, veiem l'enfocament.
Sempre que dissenyeu la lògica per a un programa de patrons, primer dibuixeu aquest patró als blocs, tal com hem mostrat a la imatge següent. La figura presenta una imatge clara del patró.
Cada programa de patrons té dos o més de dos bucles. El nombre del bucle depèn de la complexitat del patró o de la lògica. El primer bucle for funciona per a la fila i el segon bucle funciona per a la columna. En els programes de patrons, Java per bucle s'utilitza àmpliament.
En el patró anterior, el fila es denota per i i la columna es denota per j . Veiem que la primera fila només imprimeix una estrella. La segona fila imprimeix dues estrelles, i així successivament. El de colors blocs imprimeixen el espais .
Anem a crear la lògica per al patró, dona més amunt. Al fragment de codi següent, estem començant el valor de la fila i la columna des de 0. També podem començar des de l'1, és la vostra elecció.
