class definition
public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello World!");
}
}
public abstract final class nameOfClass extends Super implements Interfaces
{
ClassBody
}
A definition that specifies a class and includes the class body to define a class 1 or more constructors for the class source file with the same name as the class and extension .java class methods, class variables, instance methods, instance variables Classes
if a class definition does not contain the extends keyword
then the class is a subclass of Object class
class declaration, class body

interface definition
public interface Drawable
{
public abstract Image drawImage();
public abstract Image drawImage(int height, int width);
public abstract Image drawBlackAndWhiteImage(int height, int width);
}

{
InterfaceBody
}
to define an interface Interfaces interface declaration, interface body

method definition
int[] makeRange(int lower int upper) {
//body of this method
}
accessLevel static abstract final native synchronized returnType methodName (parameterList) throws exceptions
{
MethodBody
}
calls to that method to define a method Methods
