How to comment in java

Comment: It is the explanation of the meaning of the code

There is a lot of code and it is easy to forget, please add annotations and explanations-> What developers and maintainers see, not what the platform computer sees

In Java, there are three ways to mark comments: /Comments cannot be nested. In other words, you cannot simply use /* and & & & & #& & (Recommended learning: java course)

//Single-line comments

System.out.println("welcome CSDN");//打印输出welcome CSDN

Multi-line comments:/* &*/

public class HelloWorld{
	/*
	*main方法程序的入口
	*/
	public static void main(String[]args){
	}
}

Documentation comment: /**&*/

package com.bdqn.output;
/** 
*@version 1.1
*@author 王靖文
*/
	public class HelloWorld{
		public static void main(String[]args){
		System.out.println("welcome CSDN");
	}
}

Warning: In Java, /** &*/ is enclosed as a comment because the code itself may also contain a */.
