請(qǐng)問這個(gè)JAVA繼承的問題改怎么改?

父類有個(gè)結(jié)構(gòu)體長紅框這樣

public class Pageable<T> implements POJO {
    private static final long serialVersionUID = -410571025796786344L;
    private int pageSize;
    private int page;
    private Collection<T> data;
    private int length;

    public Pageable() {
    }

    public Pageable(int page, int pageSize, int length, Collection<T> data) {
        this.page = page;
        this.pageSize = pageSize;
        this.length = length;
        this.data = data;
    }

子類 page pagesize data 都沒有,應(yīng)該怎么辦？
改了之后還是紅字了。。

public class NewPageable<T> extends Pageable<T> {
    private int total;

    public NewPageable(int page, int pageSize, int total, Collection<T> data) {
        super(page, pageSize, data);
        this.total = total;

    }

    public int getTotal() {
        return total;
    }

    public void setTotal(int total) {
        this.total = total;
    }

}
