In Java programming, clarity and readability are paramount. As developers craft intricate algorithms and intricate logic, the need for comprehensive explanations becomes evident. Enter Java comments – a simple yet powerful tool for annotating code and enhancing its comprehensibility.

"Code tells you how; Comments tell you why." - J. P. Sousa

Single-line 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 comment
System.out.println("Hello World");

System.out.println("Hello World"); // This is a comment

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:

/* The code below will print the words Hello World
to the screen, and it is amazing */
System.out.println("Hello World");

Java comments serve as indispensable companions on the journey of software development. Whether elucidating individual lines of code or documenting entire systems, their role in fostering clarity and comprehension cannot be overstated. So, the next time you embark on a coding adventure, remember to let your comments shine – for they are the guiding lights in the realm of Java programming.
