PHP Half Way Home (3) Preface Reflecting on some of the recently written things, I feel a little bit For coder that has learned java or C ++, The syntax is meaningless, such as OOP and exceptions. Instead of simply looking at the instance code, If you don't understand it, you can google it ~ START! I am not writing dead knowledge on the blog for the time being. I suggest you write a blog on the blog f

During the reading process, write the code in the document yourself and let them operateYes. I learned this way, in fact, every programmer is doing so. After reading the tutorials and documentation, try writing something.Come out. Write anything, even if it is written by others can b

This paper mainly introduces 3 kinds of methods of creating objects directly in JavaScript object. The objects created in the following three ways are equivalent to the effect that is achieved.

First, to write unnecessary code1. You should not write those code before real demand comes.2. Do not write unnecessary code, and delete unused code.Second, the code is difficult to modify1, make too many assumptions about the future.2. Write code without careful design (basic design is not done)3, the design process should be based on what you now know exactly what needs, rather than what you think the future will arise.Iii. Excessive pursuit of univ

Example 3 of AlertDialog in Android (one-way selection confirmation dialog box), androidalertdialog In Android development, we often need to pop up some dialogs on the Android interface, such as asking users or asking users to choose. These functions are called the Android Dialog box. The AlertDialog implementation method is the builder mode. The following is a simple simulation of a selection confirmation

? That is not to be certain. This once again puts forward the programmer to learn to consider both theoretical issues and practical issues. The algorithm should be considered together with practical problems and procedures.The teacher has been training us for the team this semester. Individual projects are generally based on interests and hobbies. And good project development will not open the team, the importance of the team is self-evident. To do a good team development, we must learn to commu

the try block is executed, the code in the finally block will be executed regardless of whether an exception occurs or if the try or catch block contains a return, continue, or break statement.If no exception occurs, the control skips the try block and enters the finally block.If an exception occurs during the execution of a try block, and the corresponding catch block contains a break, continue, or return statement, the control first passes through the finally block before performing a break,
