Static Method Restrictions
Advanced Practice Question
Format: Static Method Restrictions
Which statement would cause a compilation error inside a static method?
Which statement would cause a compilation error inside a static method?
public class Example {
private int x = 5;
private static int y = 10;
public static void method() {
// Which statement causes error?
}
}
Difficulty: Hard |
Topic: Static Method Restrictions |
Cycle: 2 (Advanced)
Why This Answer?
Static methods cannot access instance variables (x) directly because static methods are not tied to any specific object. y is static so it's accessible.
Common Mistake
Watch Out!
Forgetting that static methods can't see instance variables without an object.
AP Exam Strategy
Static = no 'this'. Can't access instance variables without creating an object first.
