简介: Java中的强制类型转换(Explicit Type Casting) 一、引言 在Java编程语言中,类型转换是一个重要的概念,它允许我们将一个数据类型的值转换为另一个数据类型的值。除了自动类型转换(也称为隐式类型转换)外,Java还支持强制类型转换(也称为显式类型转换),它允许我们显式地将一个数据类型的值转换为不兼容的类型...
In standard C programming, casting is done viaoperator(), with the name of the type to convert to placed inside the parentheses, and the value to convert to placed immediately to the right of the closing parenthesis. In C++, this type of cast is called aC-style cast. You may still see...

Learn how to define custom implicit and explicit type conversions in C#. The operators provide the functionality for casting an object to a new type.
The developer intent in casting from one type to another is not communicated. Code that contains C-style casts are difficult to understand and debug. Avoid C-style casts. C++ introduces explicit casting operations that are easily identified and that clearly communicate the developer intent behind ...
Disallow cast from other checked pointer types to nt_array_ptr in checked scopes because the source pointer might not point to a NULL_terminated array. Casting from an unchecked pointer to a nt_arr...

This section describes type casting supported in Java: up casting (widening reference conversion) and down casting (narrowing reference conversion). Cast operation can be written explicitly with the cast operator (T), or implicitly with no operator.©...
