Question
Which of the following statements are incorrect?Select one:when object of class is declared, each object contains its own copy of static variablesstatic methods must only access static datastatic methods can not refer to this or super in any waystatic methods can call other static methods only
Solution
The incorrect statement is: "when object of class is declared, each object contains its own copy of static variables".
Explanation: In Java, static variables are class variables, not instance variables. When a static variable is declared in a class, only one copy of the static variable is created and shared among all objects of the class, rather than each object having its own copy of the static variable.
The other statements are correct. Static methods can only access static data, they cannot refer to 'this' or 'super' in any way, and they can call other static methods.
