Java dosen’t recognize that object belongs to subclass Code Answer

Hello Developer, Hope you guys are doing great. Today at Tutorial Guruji Official website, we are sharing the answer of Java dosen’t recognize that object belongs to subclass without wasting too much if your time.

The question is published on by Tutorial Guruji team.

So I’m doing some coursework about making a little game’s prototype. I have these simple classes (and some others that are not relevant):

abstract class Weapon {
    int damage;
    int cost; 

abstract class RangedWeapon extends Weapon {
    int range;
    int rounds;

class ExtraRounds extends Item{
    int cost = 20;
    int uses = 1;
    void use(GameState state){
        if (state.currentCharacter.weapon instanceof RangedWeapon){
            state.currentCharacter.weapon.rounds += 10;


but when trying to compile this I’m getting error: cannot find symbol
            state.currentCharacter.weapon.rounds += 10;
  symbol:   variable rounds
  location: variable weapon of type Weapon

All I want is the class ExtraRounds to check if the weapon is of class RangedWeapon and act accordingly, but I don’t know where things are going wrong. Any help is appreciated


Your weapon is of a Weapon class. You have to cast it to a RangedWeapon in order to your compiler know it is a RangedWeapon:

if (state.currentCharacter.weapon instanceof RangedWeapon){
   ((RangedWeapon)state.currentCharacter.weapon).rounds += 10;
