Java-mønsterprogram forbedrer kodingsferdighetene, logikken og sløyfekonseptene. Det spørs stort sett inn Java-intervju for å sjekke logikken og tenkningen til programmereren. Vi kan trykke en Java-mønsterprogram i ulike design. For å lære mønsterprogrammet må vi ha dyp kunnskap om Java-løkken, som f.eks til Løkke gjør mens Løkke. I denne delen vil vi lære hvordan skrive ut et mønster i Java .
Vi har klassifisert Java mønsterprogram i tre kategorier:
Før vi går til mønsterprogrammene, la oss se tilnærmingen.
Når du designer logikk for et mønsterprogram, tegn først det mønsteret i blokkene, som vi har vist i følgende bilde. Figuren viser et tydelig utseende av mønsteret.
Hvert mønsterprogram har to eller flere enn to løkker. Antallet på løkken avhenger av kompleksiteten til mønsteret eller logikken. Den første for løkke fungerer for raden og den andre løkken fungerer for kolonnen. I mønsterprogrammene, Java for loop er mye brukt.
I mønsteret ovenfor er rad er betegnet med Jeg og kolonne er betegnet med j . Vi ser at den første raden bare skriver ut en stjerne. Den andre raden skriver ut to stjerner, og så videre. De farget blokker skrive ut mellomrom .
La oss lage logikken for mønsteret, gi ovenfor. I den følgende kodebiten starter vi rad- og kolonneverdi fra 0. Vi kan også starte fra 1, det er ditt valg.
