/set method, but for hibernate, this requires special attention, because hibernate from the database read data to do, is to use the reflection mechanism to call do the empty argument constructor to construct a do instance, Then using the JavaBean specification to reflect the set method to set a value for each property, if you do not explicitly declare the set method, or set method to private, will cause hibernate to fail to initialize do, resulting in a run-time exception, It is advisable to set

randomly access elements, you should use ArrayList. If the program is in a single-threaded environment, or if access is done only in one thread, it is more efficient to consider non-synchronous classes. If multiple threads might manipulate a class at the same time, the synchronized class should be used. Pay special attention to the operation of the hash table, and the object as Key should correctly replicate the Equals and Hashcode methods. Try to return the interface rather than the actual typ

. h is the header file,. C is the source file, in fact both are code, why do you want to make such a distinction? There are several main benefits: first, the header file is used for sharing, only with an # include can be included, of course. C may also contain; second, if you want to write the library, but you do not want to expose your source code, you can compile. C into. obj or. Lib for others, and then use the. h as the instruction manual. So in general,. h is all declarations,. c all are re

The following small series for you to share a ajax+php implementation of no-refresh verification of mobile phone number instances, with a good reference value, I hope to be helpful to everyone.

In mobile app development, we often encounter scenes from Web request images to devices.If the request is repeated each time, wasting traffic, wasting power, the user experience is also poor;It is also a strategy to persist pictures to disk, but there is also a certain IO cost to read pictures from a file, and even with this strategy, we need to control the capacity of the disk cache to avoid consuming too much system resources.In fact, no solution can be said to be the perfect solution, only th

We can use GetAttribute and setattribute in JavaScript to manipulate element attributes of elements. In JQuery, you are provided with a attr () wrapper set function that allows you to manipulate the attributes of all the elements in the wrapper set:Although we can use REMOVEATTR (name) to delete element properties, the corresponding DOM attribute is not deleted, only the value of the DOM property is affected. For example, removing the readonly element attribute of an INPUT element causes the cor

in the body loading process, the body is loaded, and when the Window.onload event is triggered, the imgThe object may not have finished loading, and the Img.onload event will fire after Window.onload.Based on the above problem, consider the browser compatibility and page load time, try not to put too many images in the image object, otherwise under the FFwill affect the download speed of the page. Of course, if you do a pre-load function after window.onload, there will be no FF problems.You can

the text aligned to the "I am a card-wow" text in the back, Bottom is aligned with the bottom of the parent tag, and if you are familiar with the line box model and understand the nature of the heights, you will see why Line-height will change the position of the bottom of the label. This understanding helps to understand the process and principles of vertical-align:middle in force below.Example six: MiddleSee the following CSS code:. box{background:black; color:white; padding-left:20px;}.

own alignment value of 4, and the alignment value is 2, so the valid alignment value is 2. So the order is stored in 0x0002, 0x0003, 0x0004, 0x0005 four consecutive bytes, in accordance with 0x0002%2=0. The third variable, C, has its own alignment value of 2, so the valid alignment value is 2, which is stored sequentiallyIn 0x0006, 0x0007, in accordance with 0x0006%2=0. So from 0x0000 to 0x00007 a total of eight bytes is stored in the C variable. and C has its own alignment value of 4, so the v
