Type safety: Unchecked cast from Object to ArrayList

表明Object转化为ArrayList这个转化并不是安全的..

编译的时候需要加入修饰符才能正常编译(具体是那个修饰符..不记得了.^_^),否则会提示有警告

当然这只是一个警告,如果楼主自信这个转化是没问题的,就可以在其所在函数前加上注解@SuppressWarnings("uncheck")这样就可以去掉那条难看的提示警告的小黄线了..

但是不鼓励这么做,楼主还是应该使用安全的类型转换

Java - Warning: Unchecked cast from object to array list

Warning: Unchecked cast from object to array list 本文地址:http://blog.csdn.net/caroline_wendy 警告发生在对象(Object)强制转换为数组(ArrayList)类型,如: infos = (ArrayList<VideoInfo>) data.getData(); 因为对象转换为数组类型,未经过检查,有一定危险. 使数组对象强制转换,如ArrayList<?>,比较容易控制风险. 但是,为了书写

将Object转换成List<?>，避免Unchecked cast: 'java.lang.Object' to 'java.util.List<java.lang.String>'

java中如果需要将一个object转成list,大部分人会直接使用强制类型转换:(List<String>) obj这样.这样强制转换编译会提示Unchecked cast: 'java.lang.Object' to 'java.util.List<java.lang.String>',编译器的意思该强制类型转换并未做类型校验,强制转换并不安全,可能会抛出异常导致程序崩溃.在很多博客中有人会建议用@SuppressWarnings("unchecked")解

How to cast List<Object> to List<MyClass> Object集合转换成实体集合

List<Object> list = getList(); return (List<Customer>) list; Compiler says: cannot cast List<Object> to List<Customer> 不能将Object集合强制转换成实体集合! you can always cast any object to any type by up-casting it to Object first. in your case:

消除unchecked cast Warning

在Java中,经常会将一个Object类型转成自己想要的Map.List等等.通常的做法是: Object obj = ....; Map<String, String> castMap = (HashMap<String, String>) obj; 在这里会产生unchecked cast warning,有代码洁癖的就会想办法干掉它.解决办法就是在方法上添加一个注解@SuppressWarnings("unchecked") ,比较优雅的方案就是提供一个工

Android中Intent传递Object和ArrayList<Object>对象---笔记

首先看一下Intent的官方的API. 传递一些基本类型数据的方法如下: putExtra(String name, int value) putExtra(String name, String value) putExtra(String name, float value) putExtra(String name, double value) putExtra(String name, long value) putExtra(String name, boolean value) pu

JAVA泛型中的类型擦除及为什么不支持泛型数组

一,数组的协变性(covariant array type)及集合的非协变性设有Circle类和Square类继承自Shape类. 关于数组的协变性,看代码: public static double totalArea(Shape[] arr){ double total = 0; for (Shape shape : arr) { if(shape != null) total += shape.area(); } return total; } 如果给 totalArray(Shape[
