This is more a question about structure than coding. So i have a class named Planet and all planets have their modifiers for example: Is breedable? Damageable? etc. I already have a base planet class but i dont know how i will do that in a scalable way since i need to check if any planet has a certain modifier.

BasePlanet class:

public class BasePlanet {      private String name;     private String[] about;     private long entranceTax;     private boolean locked, pvp;      private int minRank;      private World planetWorld;     private Location spawn;     private Material icon;      public BasePlanet() {     }      public BasePlanet(String name, int minRank, long entranceTax,                       boolean pvp, boolean locked,                       Material icon, String... about) {         this.name = name;         this.about = about;         this.minRank = minRank;         this.entranceTax = entranceTax;         this.locked = locked;         this.icon = icon;         this.pvp = pvp;         this.planetWorld.setPVP(pvp);     }      ... Getters and Setters 

Implementing BasePlanet

public class Mars extends BasePlanet{      public Mars() {         super("Mars", 0, 0,                 true,                 false, Material.RED_SANDSTONE,                 "Este planeta contém pedras preciosas",                 "e itens especiais que nenhum outro planeta tem,",                 "ao menos que alguém tenha comercializado até",                 "este pequeno e cheio de surpresas, planeta vermelho."         );     }  }
