Programming | program | programmer | object | concept If you've never used an object-oriented language before, you'll need to understand the concept before you start writing Java code. You need to understand what objects are, what classes are, how objects and classes are related, and how messages are communicated between objects. The previous section of this tutorial will describe the concept of object-orie

not see the very big effect, because the work is no longer to the school as all the knowledge has the systematic study. In the internet age, all the information needed can be easily found through search engines, which is an era when you have to find useful and systematic sorting out for yourself, or more laborious. So we need to have a second choice, how to shorten their learning path, how to improve their competitiveness. We can not work blindly, but need to choose a good platform to learn. Do

On the road ahead, clear all obstacles, and you will surely go this way again, and next time you come here, you will find that there are no obstacles on the way. This is how software is developed.Maybe it will take you a little more time to solve this problem. But in the long run, it will help you save more time. When adding new features, we will first clean up the code needed for this feature. Take a moment to gradually clean u
