Explanation. Comments are used to explain the purpose of code, its functionality, or any complex logic. They provide insights into the code's intention, making it easier for other developers (or your future self) to understand the code.
// Calculate the sum of two numbers
int sum = num1 + num2;
int sum = num1 + num2;
Readability: Comments can improve code readability by breaking down complex algorithms or explaining tricky parts of the code.
// Check if the user is eligible for voting
if (age >= 18) {
// If age is 18 or above, the user is eligible
System.out.println("You are eligible to vote.");
}
// If age is 18 or above, the user is eligible
System.out.println("You are eligible to vote.");
}
Documentation: Comments serve as documentation for the codebase, helping developers understand how to use classes, methods, or functions
