聊一聊Java 泛型中的通配符 T，E，K，V，？
weixin_30474613的博客

前言 Java 泛型（generics）是 JDK 5 中引入的一个新特性, 泛型提供了编译时类型安全检测机制，该机制允许开发者在编译时检测到非法的类型。 泛型的本质是参数化类型，也就是说所操作的数据类型被指定为一个参数。 泛型带来的好处 在没有泛型的情况的下，通过对类型 Object 的引用来实现参数的“任意化”，“任意化”带来的缺点是要做显式的强制类型转换，而这种转换是要求开...

T和？的区别 @Test public void testOne(){ // ?做对象的泛型来用 List list = findAllList(1); list.forEach(temp ->{ System.out.print(temp); }); System.out.println(); List lists = findAllList(2); lists
java泛型中?和T有什么区别？

T 代表一种类型 加在类上:class SuperClass<A>{} 加在方法上: public <T>void fromArrayToCollection(T[] a, Collection<T> c){} 方法上的<T>代表括号里面要用到泛型参数，若类中传了泛型，此处可以不传，调用类型上面的泛型参数，前提是方法中使用的泛型与类中传来的泛...

要将代码修改为下限报警，我们需要调整报警逻辑，使其在检测值低于设定的下限值时触发报警。以下是修改后的代码，主要更改了报警判断条件和相关的显示逻辑： ```c // ...（前面的头文件和定义保持不变）... ...
