java抽象类怎么存数据数组

public abstract class MyClass {

    // 声明静态数组
    private static int[] myArray;
    
    public static void main(String[] args) {
        myArray = new int[10];
        myArray[0] = 10;
    }
}

public abstract class MyClass {

    public abstract int[] getMyArray();
    
    public class MySubClass extends MyClass {
        
        private int[] myArray;
        
        @Override
        public int[] getMyArray() {
            return myArray;
        }
    }
}

public class DataRepository {

    private int[] myArray;
    
    public int[] getMyArray() {
        return myArray;
    }
    
    public void setMyArray(int[] myArray) {
        this.myArray = myArray;
    }
}

public abstract class MyClass {

    public abstract DataRepository getDataRepository();
    
    public class MySubClass extends MyClass {
        
        private DataRepository dataRepository;
        
        @Override
        public DataRepository getDataRepository() {
            return dataRepository;
        }
        
        public int[] getMyArray() {
            return dataRepository.getMyArray();
        }
    }
}
