Java comments are statements that are not executed by the compiler and are used to provide information about the code. They are used to explain the code to the reader or to disable a part of the code temporarily. Java comments are ignored by the compiler and do not affect the execution of the program.
There are three types of Java comments:
Single-line comments start with two forward slashes (//) and continue until the end of the line. They are used to provide short explanations or to disable a single line of code. For example:
// This is a single-line comment
int x = 5; // This line of code is disabled
Multi-line comments start with /* and end with */. They are used to provide longer explanations or to disable multiple lines of code. For example:
/* This is a multi-line comment
It can span multiple lines
This line of code is disabled */
int y = 10; // This line of code is enabled
Documentation comments start with /** and end with */. They are used to generate documentation for the code using tools like Javadoc. For example:
/**
* This method adds two numbers
* @param a the first number
* @param b the second number
* @return the sum of a and b
*/
public int add(int a, int b) {
return a b;
}
Here are some best practices for using Java comments:
Java comments are an important part of writing clear and understandable code. They provide information about the code to the reader and can be used to disable parts of the code temporarily. By following best practices for using Java comments, you can make your code more readable and maintainable.
