关于泛型。
类KerryPagination:
public class KerryPagination{
private List<T> listShow = new ArrayList<T>();
public KerryPagination(List<T> gg) {
this.listShow = gg ;
}
}
在类PaginationBean中实例化KerryPagination:
List<TGameList> gg = new ArrayList<TGameList>();
KerryPagination kerry = new KerryPagination(gg);
请问下这样写哪里有问题?要怎么写
------解决方案--------------------List<T> gg = new ArrayList<T>();
KerryPagination kerry = new KerryPagination(gg);
需要的是List里包含的是<T>的数组啊,你就得传个包含T的过去
------解决方案--------------------那你就别用泛型了,有必要的话根据需求强制转换
------解决方案--------------------public class KerryPagination{
private List<?> listShow = new ArrayList<?>();
public KerryPagination(List<T> gg) {
this.listShow = gg ;
}
}
------解决方案--------------------public class KerryPagination<T>{
private List<?> listShow = new ArrayList<?>();
public KerryPagination(List<T> gg) {
this.listShow = gg ;
}
}
这样写
------解决方案--------------------List<TGameList> gg = new ArrayList<TGameList>();
KerryPagination kerry = new KerryPagination<TGameList>(gg);
------解决方案--------------------
private List<?> listShow ;或者private List<?> listShow = null;
------解决方案--------------------public class KerryPagination<T>{
private List<T> listShow=new ArrayList<T>() ;
public KerryPagination(List<T> gg) {
this.listShow = gg&nbs
