How to apply type erasure in java

1. If the type parameters are not restricted, replace all type parameters in the general type with their boundaries or objects.

Therefore, the generated bytecode only includes ordinary classes, interfaces and methods.

2. Insert type conversion when necessary to maintain type safety.

3. In order to maintain polymorphism in extended generic types, generate bridge methods.

Example

List<String> list1 = new ArrayList<String>();
List<Integer> list2 = new ArrayList<Integer>();
System.out.println(list1.getClass() == list2.getClass());
 
// 打印 true
