Comments
Definition - What does Comments mean?
Comments, in Java, explain the actions of a particular piece of code. They are used to provide a summary of the code in plain English to help future developers better understand the code.
Techopedia explains Comments
There are five types of comments in Java:
Block comments give a file or method overview and also may be used within a method. A block comment method is declared as follows:
/*
*block comment describing the overview of the code.
*/
Single-line comments are short comments that may be written in a single line. If a single-line comment does not fit in the same line, a block comment must be used. The following is an example of a single-line comment:
If (conditional statement) {
/* execution of conditional statement*/
...
}
/* is the delimiter for a single-line comment.
Trailing comments are very short comments written in the same line of code that is being described. The delimiters are /*…*/.
End of line comments are written at the end of the line, and the delimiter is //.
Documentation comments, written before the declaration, are used to explain Java interfaces, classes, constructors, methods and fields. The delimiters are /**...*/.
