Java Type Casting Guide

In Java, you can convert a reference type to another reference type using the casting operator. The syntax for casting is as follows:

// 将obj转换为T类型
T t = (T) obj;

Here, T represents the target type and obj represents the object to be converted. It is important to note that forcing a conversion may result in a ClassCastException, so it is recommended to use the instanceof keyword for type checking when performing a forced conversion to ensure the safety of the type conversion.
