Java Comments

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:

              // This is  a java comment

Java multi-line comment: 

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

                Following is Multi line java comment:

                   /* The code below will print the words              Hello World to the screen, and it is               amazing */

                    System.out.println("Hello World");
