enumeration object definition allows you to get all the enumerated instances and return them as an array. You use these two methods to simply display the contents of the opconstants: Showenum.java public class Showenum {public static void Main (string[] args) {for (Opconstants constant: Opconstants.values ()) { System.out.println (constant.tostring ()); } }} basically println () automatically calls ToString (), so it's

Definition and main types of software defects We analyze software defects, the so-called "software defects", that is, the computer software or programs in the existence of some kind of damage to the normal operating capacity of the problem, error, or hidden functional defects. In general, the attributes of software defects include defect identification, defect type, severity of defect, defect priority, source of defect, cause of defect and so on. Soft

, and the definition of object structure. Needless to say, the key is the customization of the structure of the object (which is the declaration of the class in the object-oriented). Next, is the implementation. One is the structure file The structure includes: English name, Chinese display name, type, display template (or reference), default value, etc. In fact, the schema-like things, and then save these structures in a file, many operations can be

, enter a number 5 for the function.This defines a simple function. In fact, the main purpose of defining a function is to make it more convenient to call, such as a lot of buttons to call this function, and the input parameters are different, then the usefulness is reflected. For example, call the above function cont:On (Press) { Cont (6)//output 18 } On (Press) { Cont (7)//Output 21 } On (Press) { Cont (8)//Output 24 } The advantage of using a function is that you can set the interval of tim

When debugging open source code, you want to see the definition of a function, you need to locate its location. In an IDE like Zend Studio, you can automatically prompt, but what can we do when there is no such development tool installed? Refer to the following code, perhaps including what you need. Copy Code code as follows: function A () { } Class B {Public function f () {}} function Function_dump ($funcname) {try {if (Is_array (

Metadata is the markup information in the: NET assembly. It is in the code to choose to go to the definition of the bar. Because the source code was not found, vs reads the information in the metadata through reflection to generate that. Workaround:1. Add the project to the solution first.2.

The function definition of JS has the following two kinds of ways: (1) A typical function declaration function Slide (arguments) { //...code } (2) Defining a function as a function expression var slide = function (arguments) { //...code } Although the above two ways are logically equivalent, there is a slight difference: Difference One: The function in example one is loaded into the scope before the execution of the code, and examp

What is a JSON Web Token?The Json Web Token (JWT) is an open standard (RFC7519) that defines a simple and independent way to securely transfer information between parties to a JSON object. This information can be verified and trusted by digital signatures. The JWT can be signed using either a Secret (HMAC algorithm) or a public/private key pair with RSA JWT. Further explain some of the concepts of this definition. Compact:Because of its smaller size
