Javadoc Example
Javadoc is a tool in Java for generating documentation from source code comments. It helps developers create documentation for their classes, methods, and fields. Here’s an example of how to use Javadoc comments in your Java code.
/**
* This is a Javadoc comment for a class. It provides an overall description of the class.
* You can include information about the purpose of the class, its usage, and any important details.
*/
public class MyClass {
/**
* This is a Javadoc comment for a constructor.
* @param param1 A description of the first parameter.
* @param param2 A description of the second parameter.
*/
public MyClass(String param1, int param2) {
// Constructor implementation
}
/**
* This is a Javadoc comment for a method.
* It provides information about what the method does, its parameters, and return value.
* @param input A description of the input parameter.
* @return A description of the return value.
*/
public int myMethod(String input) {
// Method implementation
return 0;
}
/**
* This is a Javadoc comment for a field.
* It provides information about the purpose and usage of the field.
*/
private String myField;
/**
* This is a Javadoc comment for a static final constant field.
* It can include information about the constant's value and usage.
*/
public static final int MY_CONSTANT = 42;
}
In the example above:
-
The Javadoc comment for the class provides an overall description of the class.
-
The Javadoc comment for the constructor describes its parameters.
-
The Javadoc comment for the method describes its purpose, parameters, and return value.
-
Javadoc comments use
@paramto document method parameters and@returnto document the return value. -
Javadoc comments for fields provide information about their purpose and usage.
Once you have added Javadoc comments to your code, you can generate documentation using the javadoc tool provided by Java. Here’s a command to generate HTML documentation for your code:
javadoc -d doc -sourcepath src com.example.MyClass
In this command:
-
-d docspecifies the output directory for the generated documentation. -
-sourcepath srcspecifies the source code directory. -
com.example.MyClassis the fully qualified name of the class for which you want to generate documentation.
Running this command will generate HTML documentation in the “doc” directory, which you can open in a web browser to view the documentation for your code.
