What is a static method in Java?
A. A method that can only be accessed within an instance of a class
B. A method that belongs to the class rather than any object instance
C. A method that cannot access static variables
D. A method that can only be accessed through an object
What is a non-static (instance) method in Java?
A. A method that belongs to the class rather than any object
B. A method that belongs to a specific instance of a class
C. A method that cannot be overridden
D. A method that can only access other non-static methods
How can a static method be accessed in Java?

B. Using the this keyword
C. Using the class name
D. Using the super keyword
Can a static method access instance variables directly?
A. Yes, always
B. No, it can only access static variables
C. Yes, but only if the method is final
D. Yes, but only if the method is private
Can a non-static method access static variables directly?

B. When a method performs operations not dependent on instance variables
C. When a method is frequently overridden in subclasses
D. When a method must be synchronized across instances
Can static methods be overridden in Java?
A. Yes, they can be overridden like instance methods

B. They can access static and instance variables
C. They cannot be synchronized
D. They belong to the class rather than the object
How does the this keyword function within a non-static method?
A. Refers to the class itself
B. Refers to the current object instance
C. Refers to the parent class
D. Refers to a static variable
What is the purpose of the static keyword in method declaration?
A. To indicate the method belongs to the class, not instances
B. To make the method synchronized
C. To allow the method to be overridden in subclasses
D. To prevent the method from accessing instance variables
What is the default access modifier for a static method if none is specified?
A. public
B. private
C. protected
D. package-private (default)
Can a static method access this or super keywords?
A. Yes, this can be used in static methods
B. Yes, super can be used in static methods
C. No, neither this nor super can be used in static methods
D. Yes, both this and super can be used in static methods
Which of the following can a static method NOT do?
A. Access static variables
B. Call other static methods
C. Access instance variables
D. Access static methods in other classes
Can a non-static method be called from a static method?
A. Yes, directly
B. Yes, but only through an instance of the class
C. No, it causes a compile-time error
D. Yes, but only if the non-static method is public
Which of the following correctly distinguishes static and non-static methods?
A. Static methods can access instance variables, non-static methods cannot
B. Non-static methods can access both static and instance variables, static methods can only access static variables
C. Static methods belong to the object, non-static methods belong to the class
D. Non-static methods cannot be synchronized, while static methods can
When is a static method called?
A. When an instance of the class is created
B. When the class is loaded into memory
C. When an instance method of the class is called
D. When the class is unloaded from memory
Can static methods be inherited?
A. No, static methods are not inherited
B. Yes, and they can be overridden
C. Yes, and they are hidden, not overridden
D. Yes, but they cannot be hidden
What is the result of trying to override a static method in a subclass?
A. The subclass method will hide the superclass method
B. A compile-time error occurs
C. The subclass method overrides the superclass method
D. The subclass method is ignored
Which of the following is a valid declaration of a static method in Java?
A. public void myMethod() {}
B. static public void myMethod() {}
C. private static void myMethod() {}
D. static void myMethod() {}
