Typecasting is amethod in C language of converting one data type to another. There are two types of typecasting. 1. Implicit Type casting − This conversion is done by the compiler. When more than one data type of variables are used in an expression, the compiler converts data types to...
There are two types of data types in Java: Primitive data types: The primitive data types include boolean, char, byte, short, int, long, float and double. Non-primitive data types: The non-primitive data types include enum, Classes, Interfaces, and Arrays....
Abstraction can be of two types, namely, data abstraction and control abstraction. Data abstraction means hiding the details about the data and control abstraction means hiding the implementation details. In object-oriented approach, one can abstract both data and functions. However, generally, the ...
Inheritance is a process in which one object acquires all the properties and behaviors of its parent object automatically. In such way, you can reuse, extend or modify the attributes and behaviors which are defined in other class. The class which inherits the members of another class is call...

If you are using deriving for the Status and Severity types, the Compiler will implement the ordering according to the ordering of the constructors in the type declaration. That is Green < Yellow < Red and Low < Middle < High:data Status = Green | Yellow | Red deriving (Eq, Ord) data...
class Promise { constructor(executor) { this.state = 'pending'; this.value = undefined; this.reason = undefined; this.callbacks = []; const resolve = (value) => { if (this.state === 'pending') { this.state = 'fulfilled'; this.value = value; this.callbacks.forEach((callback) =...
在这类For循环中,你应该将":"看成"in",所以,在该例中可以看成"for Object o in c"。你可以发现这种For循环更具可读性。 3、自动置入/自动取出(Autoboxing/unboxing) Java有基本数据类型,在这些基本数据类型周围又有包装类。通常,编程人员需要将一种类型转换成另一种。看看Listing C.中的代码片断。
