How do I make a JAVA Function without having to return a value?

Question

Could someone help me in making a JAVA Function without having to return a value?

Answer 1

We use void return type functions for this. These functions don't have a standard return type and are replaced with void. This means that void functions aren't called to return a value, they are called as statements. 

For instance, the following is an example of how a void function is defined:

public static void helloworld(int a){}

You can simply call this method via:

helloworld(3);

Instead of using a variable to store the return value of the function.
