How do you call methods that don't return a value in Java?
-
I'm confused as to how you call methods that don't return values. I understand calling ones that do return values but not ones that don't. I'm still a beginner at Java. Thanks in advance!!

Answer:
Calling methods that don't return values is exactly the same process as calling ones that do return them. example: public void my_method() { // do something } then call it by doing: my_method(); ...and public void my_method() { // do something return true; } then call it by doing: my_method(); .. but if you want to make a variable equal to the return value then do: bool x = my_method(); // with whatever type of variable you want

When you call methods that returns something, you sometimes want to store that something into a variable: int averages = 0; // my variable averages = calculateAverages( ); //the method that returned something. sometimes I will have a method that returns something that I want to display right away: println("Here is the average for your calculation: " calculateAverage( )); Functions that do not return a value: In Java, a function that does not return a value would have the following header: void nameOfFunction( ) { } and you'd call the function as is: nameOfFunction( );

public static void main(String[] args) { Method(); } public static void Method() { System.out.println("This method was called from main."); }
