Get Started: Java Comments

August 18, 2022

In This Article, You Will Learn about Java Comments.

Before moving ahead, let’s know a bit about Java Output.

Java Comments

Java Comments are used for better understanding & good explanation of codes and to prevent unnecessary code from executing.

Single-line Comments

In Java, single-line comments start with two forward slashes (//).

Any text that starts with // and the end of the line is not considered a code line by Java and will not be executed.

Example: Use a single-line comment before a line of code.

				
					// write the “Hello World” program.
public class Main{
    public static void main(String[] args){
        System.out.print("Hello World ");
    }
}

Example: Use a single-line comment at the end of a line of code.

				
					public class Main{
    public static void main(String[] args){
        System.out.print("Hello World "); // write the “Hello World” program.
    }
}

Java Multi-line Comments

In Java, if we have to write more than one line of comments, then use Multi-line comments that start with /* and end with */.

Example: Use a multi-line comment (like a block of comments) to explain the code.

				
					/* write the “Hello World” program
In this Java file named Main.java.
*/
public class Main{
    public static void main(String[] args){
        System.out.print("Hello World ");
    }
}
