Drelda use try-catch block maybe then exception will not generate

Answer 2

Inventory inventory;

public Character(String name, int pozX, int pozY, int power, int def){
super(name);
this.pozX=pozX;
this.pozY=pozY;
this.power=power;
this.def=def;
this.inventory=inventory;
}

Here you are setting null data of 'inventory' so you cannot add item in inventory
