Comments can be used to explain Java code, and to make it more readable. It can also be used to prevent execution when testing alternative code.
Single-line comments start with two forward slashes (//
).
Any text between //
and the end of the line is ignored by Java (will not be executed).
This example uses a single-line comment before a line of code:
Example
// This is a comment System.out.println("Hello World");
This example uses a single-line comment at the end of a line of code:
System.out.println("Hello World"); // This is a comment
Program:
public class Sample { /* This is my first java program. * This is an example of multi-line comments. */ public static void main(String []args) { // This is an example of single line comment /* This is also an example of single line comment. */ System.out.println("This program is example of command"); } }
Output:
This program is example of command
Explanation:
Now we will see multi-line Comments in java programming language
Java Multi-line Comments
Multi-line comments start with /*
and ends with */
.
Any text between /*
and */
will be ignored by Java.
This example uses a multi-line comment (a comment block) to explain the code:
Example
/* The code below will print the words Hello World to the screen, and it is amazing */ System.out.println("Hello World");
Single or multi-line comments?
It is up to you which you want to use. Normally, we use //
for short comments, and /* */
for longer.
