1. Single-Line Comments:

   • To add a single-line comment in Java, use double forward slashes (//).
   • Example:
     java

• • // This is a single-line comment int number = 42; // You can also comment after a line of code

• Multi-Line Comments:

  • To add multi-line comments, enclose the text within /* and */.
  • Example:
    java
• • /* This is a multi-line comment It can span across multiple lines */
