The void keyword is a Java keyword. This keyword allows us to create methods which do not return a value. Which means void is a special type of keyword in Java as a void keyword does not return value unlike int, double, float etc at method declaration.

Above method is a void method as it  does not return any value to the main method.

Example void method within the class
public class Example _void{  // this is a class in java public static void main(String args[]){ } public void add(){  // this is a void method. It does not produce return value; } }
