Error "Non-static variable"

Question

Hey I have been following along the java tutorial, and I ran into an error I cannot understand, or google my way to a solution.

[code]"MyClass.java:10: error: non-static variable this cannot be referenced from a static context
Animal dog = new Animal();
^
MyClass.java:13: error: non-static variable this cannot be referenced from a static context
vehicle v1 = new vehicle();
^
MyClass.java:14: error: non-static variable this cannot be referenced from a static context
vehicle v2 = new vehicle();"[/code]

I got this error after I added the new "class vehicle" the other classes, never complied with errors, what am I missing?

My code:

[code]public class MyClass{

public static void main(String[] args){

int x = sum(5,2);
System.out.println(x);

Animal dog = new Animal();
dog.bark();

vehicle v1 = new vehicle;
vehicle v2 = new vehicle;
v1.color = "red";
v2.horn();

} // end of main method.

static int sum(int val1, int val2){

return val1 + val2;

}// end of sum()

class Animal {

void bark(){
System.out.println("Woof,Woof!");

}

} // End of Animal

public class vehicle {

int maxSpeed;
int wheels;
String color;
double fuelCapacity;

void horn() {

System.out.println("Beeep!");

}
} // end of vehicle class.

} // end of Main class MyClass [/code]

By the way I used a notepad and cmd promp following along the java tutorial.

Answer 1

The issue here is that all of your separate classes are actually inner classes of your main class.
Try separating each class completely.

public class myClass{

// stuff in here

}// end main class

class Animal{

}// end animal

class vehicle{

} // end vehicle

*Notice that you ended the main class after the vehicle class, so the vehicle and Animal classes are inside the main class.*

You also forgot parenthesis after creating your vehicles.
Change:
"vehicle v1 = new vehicle;"
To:
"vehicle v1 = new vehicle();"

(Then do the same thing for v2)
