强制类型转换是一种显式的类型转换,它允许程序员指定将一个数据类型的值转换为另一个不兼容的数据类型。在Java中,强制类型转换通常用于将较大的数据类型转换为较小的数据类型,或者将整数类型转换为浮点类型(尽管这种转换在大多数情况下并不常见)。由于强制类型转换可能会导致数据丢失或精度降低,因此在使用时需要格外小...
Implicit conversion is the simplest type of conversion. This type of conversion is type-safe and no loss of data happens during conversion. These conversions deal in converting a derived class to base class. For Example,we can directly use implicit conversion if the value that needs to be stor...
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.

Compilers will often issue warnings when a potentially unsafe (narrowing) implicit type conversion is performed. For example, consider the following snippet: inti{48};charch=i;// implicit narrowing conversion Casting anint(2 or 4 bytes) to achar(1 byte) is potentially unsafe (as the compiler...
This year, I chose TypeScript to teach programming in the first year at the university. Up to now, we were using Java/Processing. I really enjoy TypeScript, since it offers access to the huge world of Javascript-Platforms while maintaining a proper coding style. Since the students may switc...

the sign is not displayed with positive values. However, if we desire to display the + sign, we may add it in the control string. If the display is desired to be left justified as well as with+ sign, add + or ++between the % sign and the conversion character; for example, the fo...
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.©...
