Comments

Comments are text that is ignored by compilers and are very useful in programming. You can use comments to explain your code to others, debug, and even layout a blue print for building your code (psuedocode).

// This is a single line comment.

/*
This 
is 
a 
multi line
comment
*/

Comments can be used to describe sections of your code.

// This is the main method. It prints the string "Hello World" to the console. 
public static void main(String[] args) {

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

}

Comments are also useful when debugging your code.

public static int add(int num1, int num2){

    return num1 - num2;

}


public static void main(String[] args) {

    // I should be getting 8...but I'm getting 2?
    System.out.println(add(5,3));

}
