How do you declare a method in Java that does not return any value?

To declare a method in Java that does not return any value, you use the void keyword. Here are the steps:

1. Start with the public keyword: This is an access modifier that means the method is accessible anywhere.
2. Follow it with the void keyword: This means the method will not return any value.
3. Then write the method name: This should be in camelCase and it's a good practice to use a verb-noun pair.
4. Open and close parentheses (): If the method takes parameters, they go in here.
5. Open a brace { to start the method body.
6. Write the code that you want the method to execute.
7. Close the method body with a brace }.

Here is an example:

public void printHello() {
    System.out.println("Hello, World!");
}

In this example, printHello is a method that does not return any value. When this method is called, it prints "Hello, World!" to the console.
