Knock more! ! ! Knock more! ! ! Knock more! ! !
Basically every beginner will encounter this problem, including me before. The reason is that I don’t like to do it. Even if I have an idea, I don’t know where to start; because you have been thinking about these things in your mind. The questions are all operations on mathematics. When you really want to use code to implement it, your mind will be blank.
A person who writes too much code, no matter how difficult your needs are, he can also write a basic framework. It is not impossible to start, because people who write too much code will summarize a set of rules, and development is all this A routine
Just like you build a house, after the basic frame is built, you only need to slowly build the bricks.
Therefore, the most important thing to learn Java is practical operation. Everyone knows that after going to a company, they will write code by hand instead of directing by the side, because the company will not give you so much power, and you will not reach this level. So what the company wants is someone who can write code, your theory is not very useful here
Everyone should know the truth that standing on the shore can’t learn to swim

Although copying code is a daily routine for programmers, beginners are not recommended to copy code. The copied code will only make you more and more messy, so that your thinking will depend on Baidu, and you have no thinking at all. How to improve yourself
The code must have its own ideas, and then turn your ideas into code implementation, this is the correct way to learn Java
