java - 迭代 List 时发生类转换异常

Question

我试图迭代长类型列表，但我得到:-

java.lang.String cannot be cast to java.lang.Long

这是我的代码:--

for(Long organid : patientTypesBean.getOrganList()){ // Exception in this line
 //... 
}

patentTypesBean.getOrganList() 返回 Long 类型的 arrayList。我什至尝试 for 循环但同样的问题

for(int i=0;i<patientTypesBean.getOrganList().size();i++){
        System.out.println("--------------Value is---->"+patientTypesBean.getOrganList().get(i));
        patientOrganEntity.getOrganListID().setParameterListID(patientTypesBean.getOrganList().get(i)); // here i get exception
    }

寻求帮助。提前致谢

编辑:-

List<Long> organList = new ArrayList<Long>();
public List<Long> getOrganList() {
    return organList;
}

public void setOrganList(List<Long> organList) {
    this.organList = organList;
}

Answer 1

你能尝试一下吗，

for(int i=0;i<patientTypesBean.getOrganList().size();i++){
    Long organ = Long.valueOf(patientTypesBean.getOrganList().get(i));
    patientOrganEntity.getOrganListID().setParameterListID(organ);
}
