In the following class

public class MyClass {
    int mNumber;
    String mString;

    public void setNumber(int number) {
         mNumber = number;
    }

     public int getNumber() {
           return mNumber;
     ]

      public void setString(String string) {
             mString = string;
       }

       public String getString() {
              return mString;
       }
}

the functions setNumber, getNumber, setString, and getString are all methods belonging to the MyClass class. mNumber and mString are the member variable. So if I then do

private MyClass someVariable = new MyClass();
someVariable.setString("A string");

I am calling the setString method on the someVariable MyClass object. Hopefully this clears things up some more. If there's anything I can be clearer on, please let me know.

Hello,

A method is a function that is associated with a class/object. In other words, it defines what a class should be capable of doing.

A method definition is the part of a method where we define the name and the parameters that it takes. For example

public void setName(String name)

would be a method definition. Please let me know if this answers your question or if there is more that i can clarify.
