Static Reference

[Alk]

Consider the following piece of code, and select the statements which are true.

class Test{
int x = 5;
static String s = "abcd";

public static void method(){
System.out.println(s + x);
}
}

1)The code compiles and displays "abcd5".
2)The code compiles, but throws an exception at runtime, because variable x isn't declared as static.
3)The code fails to compile because you can't make a static reference to a non-static variable.
4)The code will compile and display "abcd5" if x is declared to be static.
5)The code will compile by removing the static keyword from the declaration of method().
The code will compile by removing the static keyword from the declaration of method().
I thoguht the answers are 3) and 4), but 5) is also given as correct answer.

3, 4 and 5 are correct answers. How 5?
Once the amethod becomes instance (by removing static keyword), it can use instance variables. Only static methods can not use them directly, because there is no instance associated with those methods.

I come up with 3, 4 and 5.
If method() is not static, it will have valid access to both x and s.
