casting objects

Get data type: If you want to see the value and type of an expression, use var_dump ().If you just want an easy-to-read type of expression for debugging, use GetType ().To view a type, do not use GetType () and use the Is_type () function.Convert

The following only on the LS-DYNA in the simulation of stamping, forging and casting process of the functions and characteristics of the process are described:1. the physical description of the Stamping Process of the sheet metal is: under the Joint

The basic elements of the Operator programming language, which makes our code more concise and straightforward. However, in order to solve the problem of different types of operands, we have introduced the concept of forced conversion. Let's look at

(Click here, next to the previous article) Before in-depth exploration of dynamic_cast's design intent, it is worth noting that most dynamic_cast implementations are quite slow. For example, at least one common implementation is partly based on

All objects that include built-in objects are child objects of object objects.1. Array (): Build the built-in constructor function of the arrayExample: There are two ways to create an array:2. Boolean: Is an object that is not the same as a Boolean

Objective 2) Determine the result of applying the Boolean equals (Object) method to objects of any combination of the classes Java.lang. String Java.lang.Boolean and Java.lang.Object. The Equals method can is considered to perform a deep comparison

The genesis of the computer revolution is a machine. The genesis of out programming languages thus tends to look like that machine.The computer revolution originated in machines, so the production of programming languages began with the imitation of

Class Concept: A class is a collection of objects that have the same properties and services. It provides a unified, abstract description of all objects that belong to the class, including two main parts of properties and services. In an
