- Methods define actions that a class's objects (or instances) can do.
- A method has a declaration part and a body.
- The declaration part consists of a return value, the method name, and a list of arguments.
- The body contains code that perform the action.
- The return type of a method can be a primitive, an object, or void.
- The return type void means that the method returns nothing.
- The declaration part of a method is also called the signature of the method.

For example, here is the getSalary method that returns a double. |
|
public class MainClass {
double getSalary() {
return 0.0;
}
}
