Java comments are used to explain the code and make it easier to understand for other developers. There are three types of comments in Java:
1.Single-line comments:
Single-line comments start with // and continue until the end of the line. Anything written after // on the same line is ignored by the compiler. Here is an example:
// This is a single-line comment in Java
int x = 5; // This is also a comment
Multi-line comments start with /* and end with */. Anything written between these two symbols is ignored by the compiler. Here is an example:
/*
This is a multi-line comment in Java.
It can span multiple lines and is useful for documenting larger sections of code.
*/
int y = 10; // This is not a comment - it will be executed by the compiler
Javadoc comments are used to generate documentation for the code. They start with /** and end with */, just like multi-line comments. However, they have a specific syntax that is used to describe the code in a way that can be processed by a documentation generator. Here is an example:
/**
* This is a Javadoc comment in Java.
* It starts with "/**" and is used to generate documentation for the code.
* @param x the value to be squared
* @return the square of x
*/
public static int square(int x) {
return x * x;
}
In Javadoc comments, @ symbols are used to specify tags that describe the code. For example, @param is used to describe a parameter, and @return is used to describe the return value. These tags can be used by a documentation generator to create HTML or other types of documentation for the code.
