Java-kode til Rock Paper Scissors Game

Java

I denne tutorial lærer du, hvordan du laver Rock, Paper og Scissor-spil i Java-programmeringssprog, hvor den ene spiller er computer, og den anden spiller er bruger. Denne artikel indeholder simpel kildekode til Rock Paper Scissor til to spillere med korrekt dokumentation.

Hvad er Rock Paper Scissor Game?

Rock Paper and Scissor er et håndspil, der normalt spilles mellem to personer, hvor begge personer danner en af ​​tre objekter (Sten, Papir eller Saks) med en udstrakt hånd. Vinderen afgøres ud fra følgende:

  • Rock slår Scissor (Rock smadrer Scissor)
  • Saks slår papir (saks skærer papir)
  • Papir slår rock (papir omslutter rock)

Bemærk:I Hvis begge spillere laver en lignende hånddannelse, vil spillet blive betragtet som tid.

Rock Paper Scissor Game i Java

Det er nemt at lave et Rock Paper Scissor-spil i Java. Vi kan oprette et Rock Paper Scissor-spil med to spillere i Java ved at bruge if else condition og Java.util.Random.nextInt() funktion.

Java-kildekode til Rock Paper Scissor Game

Følgende kode bruger funktionen Random.nextInt() til at tage tilfældige input fra computeren (spiller 1) og bede brugeren (spiller 2) om at vælge en indstilling sten, papir eller saks og afslutter koden ved at tilføje indlejret if-else erklæringer for korrekt at rapportere "Brugeren vandt" , eller "Computer vundet" , eller "Ingen vinder vundet (begge vælger det samme). "

Output 1 (Uafgjort) 

The Computer already made it's choice

Please make yours : rock

You choose : rock
Computer choose : rock
No Winner won ( Both choose same )

Output 2 (bruger vundet) 

Options to choose from :
