tricky initial value problem

public class Example
{
private int x; // LINE ALPHA

public void method1( int a)
{
int x; // LINE BETA

...
...
...
}
}

What is the intial value of x on LINE ALPHA

What is the initial value of x on LINE BETA

my guess is that they're both ZERO
but I feel like my teacher is tricking me!!!

Nope, the first x is initialized to 0 (zero) unless you initialize it to something else; the second x is a local variable and local variables aren't automatically initialized; you have to do it yourself (or assign a value to it before you use that value of that x).

kind regards,

?? there should be an answer to LINE BETA

is the answer: local variable not initialized?
