Java Comments

Comments in Java allow you to describe the code. This makes the Java code easy to read. Whatever you add inside a comment never gets compiled. Comments in a Java program can be mentioned in the following two ways:

  • Single-line Comment
  • Multi-line Comments

Single-line comments

Use // i.e., two forward slashes for a single-line comment in Java. Whatever we mention after the slashes in a single line, will not get compiled.

Let us see an example displaying single-line comments in Java:

public class Studyopedia {

  public static void main(String[] args) {
    // Display a line
    System.out.println("This is demo text.");
  }
}

Output

This is demo text.

Multi-line comments

For multi-line comments in Java, use /*     */. Whatever we mention under /* and */, will not get compiled.

Let us see an example displaying multi-line comments in Java:

public class Studyopedia {

  public static void main(String[] args) {
    /* Display a single line
       with demo text */
    System.out.println("This is demo text.");
  }
}

Output

This is demo text.
