JDK source code

I don’t know if you have ever read the JDK source code in your spare time. Although looking at the source code feels a bit of abuse, as a programmer, looking at the jdk source code in your spare time will help you understand your daily development environment better. profound. And there are the following five advantages.

• Understand the mind
• Familiar with design patterns
• Improve the elegance of your code
• Know the principle and improve interview ability
• Improve the rigor of your own code

Although looking at the source code is a bit of abuse, you can learn a lot while being abused. If you really need to calm down and read the source code, the benefits are far more than so much. And there are various magical and ingenious designs in the jdk source code. If you are interested in the JDK source code, you might as well take a look at the JDK source code analysis from Meituan that I will introduce for you. Everyone knows that the gap is more than a little bit!
