, creating a person class, and then using prototype to extend the class, adding methods. The biggest difference with object literals is that when you invoke the class's methods, you must first be new (similar to the Java calling Class). var p = new person (); P.getname (); If you do not use new, and create directly, you will generate an error. And this error will not be false, difficult to find. The reason for the error arises from this point to the P
-term objective. The short-term objective is to work with the internal iteration and parallel processing of "Set-class batch processing" (as described below ); the long-term goal is to direct Java to the functional programming language (not to completely become a functional program

Equal is used to test whether an object is equal to another object. ToString returns a string representing the object. Almost every class will reload the method to return the correct expression of the current state. (The toString method is a very important method) 19. gener

Exception Handling is an important part of writing strong Java applications. It is a non-functional requirement of each application and is used to handle any error situations elegantly, such as resource unavailability, illegal input, and empty input. Java provides several exception handling features, using try, catch, and finally Keywords are built in the languag
do it? If Microsoft does not compete with IBM for a mainframe, Google uses the objective environment of rapid Internet development as a decisive factor to avoid competing with Microsoft for OS, but uses the search engine path, known as 3rd giants. So who are the 4th giants? Many experts predict that things will appear in Asia or China. Whatever and objective environment change trends are the key to determining the general direction. Of course, I also hope it will appear in China, ^ _ ^ ~~ 2.
When learning a new programming language, we must be clear about a few questions:What is the type model of the language?Strongly typed / weakly typed, static type / dynamic typeThe type model changes the way the problem is handled and controls how the language runsWhat is the programming paradigm of language?Object-oriented, functional, procedural, etc.How to int
